2000 Chevy Silverado Vibration - II

He said that he was advised by GM to replace the steering system with 2500 system. Apparently GM is telling dealers with buybacks to replace with 2500 steering system (what exactly...I don't know). He was told that the new 2500 steering system had worked on other vehicles.
They have the truck on the rack (been there for about 2 months) and waiting on parts. He is going to let me know if it works.
Anyway, to respond to your post...... I think GM will authorize the 2500 parts on your truck if you push them. By-the-way, if my service manager says the 2500 parts work, I'll let you know exactly what he did (I may have to buy him lunch) to fix the problem so you can use the information when you push GM. I'll try to get the VIN number of the truck to really impress the GM 800 operator.

My second upgrade is some sort of tonneau cover for my sportside. I like the look of over the rail bedliner that came with it, but, the local custom truck shop says they will have to cut it to put a cover on. GM's folding hard cover is $750 but I've never seen one on a truck. Those electric role up hard covers seem pretty slick but at $1400 I can buy a lot of other upgrades.
Otherwise the truck is perfect and the 5.3L V8 gets better every day. Unfortunately, the temp gauge on the mirror was working correctly this past weekend when it read 113 degrees. Thanks again for all of your advise.

Tells the service tech how to isolate the component(s) causing the problem, solution to problem (ie where to place balance wts, etc).
Apparently the service techs need to read the manuals to solve the problems that the factory created and has failed to correct, issue a recall or provide a service bulletin.
Has anyone experienced the same problem?
I'd like to have it and show it to them.
Thanks.
I've also noticed when I put in drive, it takes a split second to connect....
Re-flashing the computer may work for you. Now that it's all computer based or related, that might be your answer....not sure though. However, might be normal...

The bouncy ride on certain parts of the highway is virtually unsafe. Then you hit a bridge crossing and it is smooth as can be. Regardless, it definitely needs better shocks since the body role is kind of sloppy. The cornering is pretty good though but it all because of the Bridgestone 285 - 18" Duelers. New shocks should make it even better.
Thanks.
1 down 2 to go. Now to find the cause of vibration felt more in the right seat at 65-70, and the kickback in the steering wheel over bumpy roads.
Miles now...8,100 in six weeks. Trip mpg was 17.87 with a 71.5 mph average. Arizona and New Mexico are a kick cruising at 85 to 90 most of the way.
Tapd - Let us fellow "bouncers" know what was replaced. Do you have the 5.3L with 3.73? My 5.3L with 4.10 gears (4x4) had its first real tank (800 miles) at 14.8 mpg of around town with some highway. My 1999 S-10 ZR2 (22,000 miles) was getting 17.5 for the same trips so I'll take a 2 mpg hit for Z71 power.
Thanks.
I do know they had a list of parts, but it was a list about 6 or seven wrong. My dealer, Hallowell Chev, was able to tell immediately that the springs were wrong. They did think that my build date of 2/00 would have had the new springs. These guys at Hallowell in Clovis, CA. are very good and I understand that the foreman there, Rick, was one of the ones to come up with the fix for driveline shudder. New springs seem to have cured the bounce problems, I won't buy shocks except to stiffen the ride and get more control.
Built in Canada, 5.3 3.42 2wd.
Got my Helm's manual(s) today. Now I understand why the service departments always say "cannot duplicate" or "supposed to be that way" or "common on all trucks". Under the Vibration Diagnosis and Correction section, there are several places where the manual states: IMPORTANT: Do NOT attempt to repair a normal condition, or the customer will probably be convinced that the vehicle has a problem. Customer satisfaction becomes extremely difficult after this point."
Vibrations must be a problem as the manual dedicates 57 pages towards identifying the various types of vibrations and possible fixes.
The Big O Tire guys said there is a new Monroe shock that rivals the Edlebrock IAS. I think I'll stick with Edlebrock when the time comes; which is very soon.
Other things to do:
replace rear windows for the 4th time
repaint back half of truck due to defects
I have logged 1200 miles on rental '00 Silverado while truck is in the shop. One thing good is that this is keeping my mileage down and actually extending my warranty period as I figured I would hit the 36,000 mile mark before 3 years...
I argued that the vibration had re-appeared on previous fixes and I feared it would re-appear after the warranty expired.
They rejected and refused at first, but finally gave in and issued the ext. warranty (6 year/75,000).
For all the trouble you've been through (more than me) I think they'll do it....if you interested....
John
I shall put this at the top of my things to do list for Monday morning...thanks

When I picked the truck up, the service writer said that the front two tires were rebalanced and the vibration was cured. It wasn't. I asked him if they indicated the tires and wheels (for out of round). he told me that they are not that high tech. Looks like the stone wall treatment is starting.
The extra 15hp (at the rear wheels per K&N) feels like it is really there and the engine has a nice throaty sound when accelerating. I ordered it direct from K & N at their website; knfilters.com for those of you who might be interested.
On another note, tomorrow makes two weeks that they have had my truck and also qualifies me for the lemon law as they have exceeded their thirty "working" days that they have had my truck. Not to mention four times for the rear windows and at least 6 for vibrations...but if they are still trying I'm all for it cause I just got too many mods on this truck.
On rental Silverado...now has over 2000 miles logged on odometer and truck rides like a dream. Just that damn 4.8 got no high end to it. Seems to just run out of oompf on the high side...smokes the 235's though.
What is with the tires on these trucks. I just had my 285/60r18 Bridgestones rebalanced for the 2nd time in 5 days at a different shop and it has done the trick. Smooth as silk on asphalt. They recommended something called a "velvet" shackle that they say really helps the back end aftershock on the freeway. Everyone has a different idea.
I have these on my 2K 2WD standard Silverado. The company advertises 20% reduction in vibration when driving with an empty box. I already had a smooth ride suspension, so I did not see a dramatic improvement - but it could be a 20% reduction. If you have a stiffer supsension, I think the improvement would be more dramatic.
I have the velvet-ride shackles with Edelbrock IAS shocks and the combination is noticeable, especially at higher speeds. Still not a luxury car ride - but better,and the handling is significantly improved, especially going around curves or making quick stops (less nosediving.)
One note, the shackles I got just barely fit in the shackle bracket - look like a universal fit type. The installer had to shave the center bolt head slightly to avoid interference with the bracket. Not a big deal.
Good luck.
still vibration between 60-70 mph. Also have noticed vibration at slower speeds. I was beginning to believe I was imagining this, but just today dealer has said there is a fix for this problem. Chevy just recently released a bulletin on this problem. This will make the 5th time I've had to take truck in for this problem. Also have a flutter noise coming from a/c vents, they say they know what is causing flutter but there is no fix. Also with V6 engine you may notice a noise coming from engine while idle and in gear like at a stop sign. It is a roar or drone type sound, Chevy knows about this they say and is working on a fix for this. Wonder what else is going to go wrong??? Just remembered my silverado has the chrome wheel appearance pkg. the plastic lug caps keep coming loose they've replaced these caps already once.
steveguitar
my loaner silverado has the a/c flutter also. I thought it was my imagination. As far as the plastic lugs on the plastic caps...I think it will always come loose...you can tighten the plastic lugs only so much before stripping them. And of course with your vibrations, they will come loose...
Thanks,
Ken
My 2000 LS 5.3 2wd ext cab is awesome. Just took a whole year to the day to get it. Had to go out of town to make the order, ( $200 bucks over invoice ), on 4/15/00 and got it on 6/1/00.
Sewell SUCKS
Did not see this bulletin on the NHTSA web site. Maybe it takes a few days to be posted on their site.
Rico
If you have a problem, at least call Chevy cust srv and get a problem tracking number. Make them keep it open.
I do know the bulletin was 12 pages long.
It will be based on your V.I.N. # so apparently they have got this worked out on the newer ones they are producing. I remember it talked about replacing the complete rack and pinion system. Replacing power steering and power steering pump.
Front coil springs and bushings. Welding in a extra support piece.
Thanks again,
Ken
I REALLY DON'T HAVE GOOD FEELINGS ABOUT THEM WELDING ON MY NEW TRUCK. WE REALLY SHOULDN'T HAVE TO BE GOING THROUGH ALL THIS SHOULD WE? MY SERVICE MANAGER SAID HE'S ROAD IN CUSTOMERS TRUCKS FOR OTHER PROBLEMS THAT HE NEW HAD THE VIBE PROBLEM AND THE CUSTOMER DIDN'T NOTICE IT. SO DOING THIS BY VIN # AND BY OUR REQUEST THEY WILL NOT BE FIXING EVERYONES ONLY THE ONES WHO HAVE COMPLAINED ABOUT THE VIBE. SEEMS LIKE THEY'RE JUST TRYING TO CUT CORNERS AND SAVE SOME MORE MONEY!!!HE ALSO SAID THE LAUNCH SHUDDER WAS ONLY ON 1999 MODELS AND NOT ON THE 2000. HE CLAIMS THIS WAS FIXED ON 2000 MODELS BUT I STILL SEEM TO HAVE IT WHEN PULLING OUR TRAVEL TRAILER. WHAT IS A PERSON TO DO? SHOULD WE JUST CALL BBB AND GO THROUGH ARBITRATION OR GET WELDED?? SOMEONE HELP...

Damn right you should let them do this. It sounds like you have a dealership trying to help. GM wants nothing more than to solve a problem, and probably will take any help, and the dealership makes money too, win win. It also sounds like GM has worked hard on a fix, this is probably it. I would not worry about the weld either. Give up immediately the notion that something is rotten because GM is not recalling them all. It's not a safety issue. Just get yours fixed, don't worry about the others, and you're liable to have a loving relationship with her thereafter.
An anecdote from me...In 1994 on my Z28, there was a drive line vibration. GM replaced the steel drive shaft with an aluminum one for anyone that asked, even after the warranty period. Mine had the steel drive shaft, but did not have the vibration so these issues don't necessarily affect all vehicles. (I kept the steel drive shaft)
Obyone,
>>#368 of 374: Welding in a extra support piece (obyone) wonder if that could be the torsion bar?<<
You surely mean "torque arm?" Only 2wd trucks have rack and pinion, and don't have torsion bars. Use coil springs instead. Did I miss something earlier about torsion bars?
Red,
Maybe there are more than one resident experts on Edmunds?
All,
My guess about the launch shudder...it's in the drive line, and worse if 2 piece drive shaft. I did feel this once, just off idle, towing a 4000 lb trailer, uphill, at barely above a standstill in bumper to bumper traffic. Mine is reg cab 4x4 with one piece drive shaft. It felt harmonic in nature, and I bet gets amplified along the longer length of a two piece drive shaft. Same principal as a piano tuning fork.
"Save all your Paper work!!!!!! my brother told me last week that they are installing stablizers on the front of the new 2001 2wd trucks. is this like fixing a non problem? news coming soon"
Prior to this email he asked me to check if there was a stabilizer bar located between my front tirewell and front door. I don't know where this is heading but sure got my curiosity...
launch shudder...
I have driven three different 2wd '00 Silverados over the past two months. The first two had different sized drive shafts. The newest manufactured 03/00 in Canada has identical sized drive shafts and no launch shudder. So what does this mean...I can only conclude that GM has a fix for the launch shudder on the newer models. But then another poster said that his had the launch shudder and was made 02/00 although at Ft Wayne. Maybe the Canadians know something....
