Chevy Silverado and GMC Sierra Steering



  • Just so you all know if the dealer installs a lift kit before you buy the new vehicle, it voids the warranty through GM. This is just something that the dealer forgets to tell you if you have trouble with it. The dealer is making approximately $6500.00 profit by putting it on and then they don't want to fix anything on it. They shouldn't be able to put them on vehicles without having them re-inspected for safety.
  • I have a 2000 Long Box 3500 GMC Sierra Diesel Dually with about 65000 miles and beefed up suspension. I carry a 11 ft. truck camper frequently and until recently hauled a 26 ft. boat. I have had the front end aligned and installed and balanced new tires The problem that occurs with and without a load is a shimmy (sometimes violent) in the front end at various speeds, on various services and at different temperatures. It can sometimes be worse when the brakes are applied or going around a curve and may disappear under identical conditions the next day. Because it is intermittant I have not been able to resolve.Any ideas?
  • Try having someone check the rotors. I've heard that some people have them turned or shaved and that takes care of the problem, but if you read other posts in the brake section you might find the answer there. You also need to make sure they cleaned inside the wheel when the tires were put on and balanced. Also make sure they do a high speed balance. I'm not a mechanic, I'm just letting you know that I've seen this on other posts and I've dealt with this on my other vehicles. Let me know if this helps.
  • 04 chev k1500/i know grease is apply, but where
  • Same exact problem on my '02 Silverado (same as post 50). Anyone respond yet to this?
  • I would also check your tie rod ends
  • i had this problem before @ 20,000 miles / the dealer grease something on the steering shaft / now @ 67,000 miles it's back

    Greasing the shaft is old news. They have a new shaft out. Costs like $50 and takes maybe 15 minutes to replace. Depending on your relationship with your dealer and previous documentation they should pick up the tab for this.
  • My 2003 Chevy Silverado Z71 is making a knocking noise that I can hear and I also slightly feel it through my steering wheel when any steering input is put into it left or right at slow speeds. Also when I get up to around 35 mph I hear a squeaking noise also coming from the front end. It is totally stock just newer tires same size as stock. Ideas? Disscuss.

    GM has a new intermediate steering shaft to replace the one causing your knocking noise. The part no. is 19153614. If you have a history of this problem with your dealership you can have it replaced free as it is a permanent fix for a problem that has started in the '99 Silverados.

    Here is the service bulletin:

    Document ID# 1893252

    Subject: Clunking Noise Under Hood and Can Be Felt in Steering Wheel and/or Steering Column (Replace Upper Intermediate Steering Shaft (I-Shaft) Assembly) #00-02-35-003M - (01/31/2007)

    Models: 2002-2006 Cadillac Escalade Models

    1999-2007 Chevrolet Silverado Models (Classic)

    2000-2006 Chevrolet Suburban, Tahoe Models

    2002-2006 Chevrolet Avalanche

    1999-2007 GMC Sierra Models (Classic)

    2000-2006 GMC Yukon, Yukon XL Models

    2003-2006 HUMMER H2

    Attention: This Service Bulletin DOES NOT include Mid-Size Utilities such as Buick Rainier, Chevrolet TrailBlazer Models, GMC Envoy Models or Oldsmobile Bravada. Refer to Service Bulletin 02-02-35-006A or newer for Mid-Size Utilities.

    This bulletin is being revised to update the repair procedure with a permanent fix.

    Some customers may comment on a clunk-type noise coming from under the hood that also can be felt in the steering wheel. These conditions may be more noticeable when turning at low speeds on rough road surfaces.

    Diagnostic Tips
    Use the information below to help diagnose the source of the noise.

    • Frame Snap and/or Popping Type Noise -- A frame snap or popping type noise can be duplicated on rough or smooth road surfaces with steering wheel input to the left or the right. This type of noise can be HEARD and is typically louder with the windows rolled down. For additional information, refer to Corporate Bulletin Number 03-08-61-002F or newer -- Snap/Popping Type Noise Coming from Front of Vehicle (Remove Front Crossmember, Change Fastener Orientation).

    • Intermediate Shaft Clunk -- Intermediate shaft clunk is heard and FELT in the steering wheel and/or steering column area, typically while driving on rough road surfaces with steering wheel input.


    Replace the I-Shaft with P/N 19153614.
    Do NOT lubricate or exercise the I-Shaft.


    • I-shaft P/N 19153614 has been designed to replace previous designed dampened and non-dampened I-shafts. The physical difference in the yoke size will accommodate all vehicles listed in this bulletin.

    • Due to the design of the new I-shaft, it is not possible to lubricate/grease the I-shaft.

    Replace the steering column upper intermediate shaft with an improved design shaft that will eliminate the clunk noise using the procedure listed below.

    Set the front wheels in the straight ahead position.
    Notice: On the 2002 and later model year vehicles, the steering column LOCK was removed from the steering column. It is critical that the J 42640 - Steering column Anti-Rotation Pin is used when servicing steering columns on 2002 and later model year vehicles. Failure to use the J 42640 may result in damage to the SIR coil.

    Set the steering wheel in the LOCK position on 2001 and prior model year vehicles.

    For 2002 and later vehicles, install the J 42640 in the steering column lower access hole.

    From under the hood, remove the lower bolt that connects the upper intermediate shaft to the steering gear coupling shaft.
    Slide the shaft towards the dash in order to disengage the shaft from the steering gear coupling shaft.
    For vehicles equipped with adjustable foot pedals, perform the following steps:
    6.1. Reposition the carpet away from the accelerator pedal position (APP) sensor.

    6.2. Remove the two nuts retaining the accelerator pedal to the bulkhead.

    6.3. Reposition the accelerator pedal out of the way so the intermediate shaft can be removed.

    From inside the vehicle, remove the upper bolt from the upper intermediate steering shaft (1) to the steering column connection.
    Remove the upper intermediate steering shaft assembly.
    8.1. From inside the vehicle, slide the shaft down and off the steering column.

    8.2. From inside the vehicle, slide the upper intermediate shaft through the dash boot seal and remove the shaft from the vehicle.

    Replace the upper intermediate shaft.
    Install the upper intermediate steering shaft through the dash boot seal and slide the lower end into the steering gear coupling shaft.
    Raise the upper end of the intermediate steering shaft and install into the steering column shaft.
    Install the upper bolt and nut.
    Tighten the bolt to 47 N·m (35 lb ft).

    Install the lower bolt and nut.
    Tighten the bolt to 50 N·m (37 lb ft).

    For vehicles equipped with adjustable foot pedals, perform the following steps:
    14.1. Reposition the accelerator pedals into position on the bulkhead.

    14.2. Install the two retaining nuts.

    Tighten the nuts to 20 N·m (15 lb ft).

    14.3. Reposition the carpet into place.

  • Wow!
    Ihad this shaft replaced in Nov. and it did absolutely nothing for the 'Chubaka Noise" coming from the left side of my '04 Silverado, but tghe mechanis did tell me that replacing the steering column would get it done and that greasing the shaft was not possible due to it being "closed".
    On the side I travelled to Colorado and on the return trip I noticed the speedometer was at 120mph! I pulled off to the side of the road and turned off the engine and to my astonishment was still doing 75-80mph!
    So, I had to "guestimate" the speed by way of other cars on the highway.
    To my surprise, when I arrived home there was a letter from GM telling me that they'd had complaints about the "jittery" instrument panel and I got it replaced for free at the dealer. All I had to do was give them my VIN, they ordered the part and replaced it in less than 45 minutes.
    I can't understand why the delay on the steering column.... :shades:

    I have an 04 Yukon XL and at about 18000 miles the steering wheel would lock up at slow parking lot type maneuvers. After having the steering pump replaced and a special larger type steering valve that is associated with the pump replaced it still had the same problem and the highly trained dealership mechanic and the GM rep. that he talked to had no clue so they gave that familiar answer that it is a characteristic of the hydroboost system. I didn't accept that for an answer because the first 18000 miles I had no problem. So I went to another dealer and at the same time contacted the higher ups at GM. The mech. at the new dealership said that my problem was not the hydroboost system (which will give a slight tug at the wheel when turning and braking, but that is it...just a slight feeling...NOT lock up for a split second) he said something is wrong with the steering box (which the factory rep. told the first mechanic not to replace) When the new steering box was replaced the problem went completely away! There is some type of written bulliten about replacing the steering box for this problem but it was not as available as other bullitens are. hope this helps.

    I have a 1997 2500 series chevy HD pick-up truck. It has variable assist steering .I change thr power steering pump and the steering box but it still doesn't get hydraulic pressure to steer the truck and there are no codes. How do I solve this problem? Rich
  • ty5ty5 Posts: 2
    I am a long time Suburban owner, but till now they where all 1500's with vacuum assist brakes. I just purchased a 98 K2500 Suburban w 7.4 and hydroboost. the brakes are great (compared to my 2 97 K1500's one LT, one is Police issue), but the has a high pitch whining sound that is RPM affected, especially when cold, and the steering is noisy at low speeds, especially at the end of the steering limits, and steering assist is almost non existent when backing in low speeds. Anyone can give me some pointers , before I start to replace the pump or steering components. I searched the Suburban forums but most of them do not have info on 2500 w. hydroboost, as this is more of a Silverado/Sierra feature, and on this forum most reference is for the 99 and newer.
  • I have the same problem, 1997 GMC Sierra 1500 4x4 ext cab, 5.7L. When I turn the wheel approx 80 deg left, there is a sudden sharp drop in steering effort ( feels like wheel came off in my hands). Problem began 3 yrs ago only 1-2 x/year, now almost every time. Also, maybe related, about 3 yrs ago after cold start, power steering remained at full boost for 5 minutes, then fixed itself. During that episode it also felt like the wheel was not connected. Any suggestions would be appreciated. Questions: does this vehicle have a steering angle sensor? Vehicle speed sensor? Anything else that may cause erratic power steering pressure?
  • I have a problem turning the truck only when its in 4wd sounds like the same problem as #55??But what its doing is almost like snow plowing when I try and turn.The truck will not take a 90 degree turn in 4wd.Like theres a spool instead of a limited slip!I bought the truck new ,never had this or really any other problem and the truck has 48,000.I took a quik look underneath and see nothing obvious!
  • My friends 2004 HD has squeaky steering that has been fixed twice now at about 100.00 a pop. Does anyone know about this or have a diagram were we can do it our selfs? From my understanding is they pull the steering shaft and use a needle grease gun to lube it. So what I am wondering if anyone else has had this problem or know of a better fix or a diagram on how to do it? Thank you for all the help in advance.

  • 2004 Silverado. Vibration and sound like running mudders at 20 mph and up. Only when going straight and turning to the left. Noise stops with right hand curves.

    I live in western pa and i have a 2005 chevy duramax 3500 4x4 that does the same thing..The power steering system looses power assist when you are moving slow in parking type situations. The bakes get harder to push also.. The dealers have changed the control valve in the power steering pump and also changed the steering box assembly.. it still gets real stiff and looses power assist and has the pump whine.. They told me the tires were low and all the other bs. We should try to do something about the steering problems as these trucks are unsafe the way they are..
  • ty5ty5 Posts: 2
    I have been driving the truck (98 K2500 Burb. LT 7.4 w. Hydroboost) for 2 months now. The brakes are sensational compared to my other late 90's 1500's with vacuum assist, even at low speeds and engine rev. (idle@700rpm) but the steering is very stiff at low revs, a two hand job even for me (6.2" & 240lb), if I can give it some gas, it is OK, so in my opinion the portioning valve that distributes the pressure/power created by the hydro pump gives most of it to the brakes for safety at low rev's. I guess we can play with the portioning valve to give more for the steering, but I do not wan to lose any stopping power!!!! I am just getting a complete GM service manual for it, I will see what I can come up with.

    gm says that "its a common trait of the truck.. I think its a safety defect. I am also a big guy and it takes 2 strong arms and then some to steer the truck..
  • crisgocrisgo Posts: 1
    I am curious if the bleeding of the steering solved the problem. I have a similar problem with a seemingly tight front end and say starting to make a left turn and the steering wheel will just let go for just a bit. Or even going down the road straight and with pressure to the left it will do this.

    i have a 2005 chevrolet silverado 1500. there is a vibration at 45 mph and 55 mph. it feels like your running over the rumble strips on the highway. has anyone else had this problem or may know how to fix the problem
  • rodneyfrodneyf Posts: 2
    i have the same problem. i cannot tell if the whining noise is fromm the front end because the noise can only be heard with the windows up? the whining is constant and increases as i pick up speed, so it is not the transmission. when i turn to the right, it stops for a second, but picks up again when i straighten out the truck? i'm being told that it could be a rear axle bearing, but i'm not convinced. i don't want to replace a thousand parts before the problem is found. did you ever find a fix for your problem?
  • I just recently installed a leveling kit on my 04 HD and since then I have developed a vibration sound that only happens between these speeds . It stops if you let of the throttle but it sounds like i am running over the ruts on the side of the freeway. has anyone had this problem or know how to fix it??

    Was this out of your pocket or is there another GM "recall"....and how do we get this info to GM if there's not?

    First, I live in Louisiana and have not heard of state inspections being rejected for this reason. Maybe this is something I can bring to the attention of LA-DOT.

    I have a 2004 Z71 which I bought new and now it has only 28K miles. I noticed the clunking in the steering wheel at about 15k miles and was told it was not a major problem and that grease would help, but the clunking did not bother me enough to take it apart. Now, I have another problem with steering which is a safety hazard. At a stop and low speeds, with or without the breaks applied, I have no power steering assistance to the left. I jacked up the left side enough to get some pressure off the wheel and noticed I can steer in both directions just fine. I checked and greased both sides and did not find anything noticeably worn on the front end. I read a service bulletin that recommends changing the gear box from a 670 to a 680.

    At the end of the day, I'm still scratching my head and looking for answers...All the help is greatly appreciated!

    I have an 04 4WD and had to have the rear slip yoke replaced because of a whinning noise. It was not there all the time but sometimes.
  • I complained to the dealer my 03 felt as if the whole front end was going to fall out. They told me they knew what it was and fixed/lubed the Intermediate steering shaft, unfortunately in just a month it was the same thing. Who has the time to give up a vehicle for a few days every month to the dealer to keep repairing the same thing. Now I know why my friends by Tundras and GM is loosing money, they keep selling us junk.
