My truck is 2000 with 3.42 ? don't know if locking or not. 4.3 V6 Short WB Auto/Air only
nothing more. I now has 3400 miles on it, I started complaining the next day I bought it.
About 20 miles on it.
Built in the Indiana Plant 6/99
They want you to put a lot of miles on it so that when they have to buy it back they can charge you for miles used. Don't listen to them demand they take it and "Try" to fix it.
Get yourself about 4 to 6 work orders from the service department showing you have been in to have it fixed, these will have the dates and miles on them.
Go back every couple of days if you have to...
It is a pain because they will keep it for at least a day to balance the tires
several different times, they will change out your tires and even possibly the front hubs, but you will need this kind of paperwork to pursue the Lemon Laws or the BBB Autoline.
Sorry for the long winded spill...best of luck.
Quit freezing topics.

THEN I CALLED CHEVY CUSTOMER SERVICE TO FILE ANOTHER COMPLAINT, THEN WAS TRANSFERRED TO A SERVICE REP MANAGER. HE ADVISED THAT THE DEALER WAS WRONG WHEN THEY DID NOT EVEN DRIVE IT TO SEE THAT THE ALIGNMENT WAS OFF CENTER AND THE STEERING WHEEL WAS CROOKED. NOW THEY ARE CALLING DEALER NO. 2 ( THEY ARE CLOSER TO ME ), AND GET IT STRAIGHT THAT THE TRUCK HAS TO BE DRIVEN TO CONFIRM THE ALIGNMENT PROBLEM AND FIX IT.

check out the complaints for 99 Chev Truck Silverado and see how many of us complained there. Bunch of vibration problems.
This will be GM's last attempt at fixing the shudder launch and cab vibration. I opened a case with GM this week and made it very clear this will be the 4th time it has been in for service to fix these 2 vibrations and if this doesn't fix the problem I want the truck bought back.
They have tried the following to fix the vibration problems:
-Balanced tires on two seperate occasions
-Replaced the rear shackles and bushings per TSB
General Tires don't fall within the guidelines set forth by the same TSB. The truck was built Jan. '99 so it SHOULD have the B9 hubs. TSB indicates no need to check if built Jan. '99 or later.

1999 Ext. Cab, 4.8, 3.42, General Tires, locking rear.
Drove a 2000 2wd 1500 with 5300, auto, extended cab, 3.42 locking rear on Saturday and it did not have the launch shudder or the high speed vibration.
Neither did the 4x4 Z71 that we drove.
-Funk
After the dealer replaced the springs, the launch shudder is gone, well 98% gone.
The rear end seems to stay in line a lot better. Before is was prone to hopping out of line quite a bit when going over "decent" bumps at speed. Front end still seems to vibrate quiet a bit over same bumps.
The in cab vibration is still there at 68-72 mph. I am not being picky about this as we drive at that speed for 40 minutes each day, one way on our commute. I am going to push for new tires/rims from the dealerhip as a test to fix. So far they have been reluctant since they would have to purchase said tires/rims from GM.

My dealer replaced the springs with this part number:
15746407
Good luck and get it fixed!
-Funk
The new springs also seem to have made the ride a little bit softer. At least my wife says she can feel a difference.
NOW THE HOOD AND REAR SEAT RATTLES WHEN HITTING ANY BUMPS.....AFTER ALL THE HASSLES WITH THE SERVICE DEPARTMENTS ( 3 DEALERS )....WILL GIVE SERIOUS CONSIDERATION TO CURING THIS VIBRATION PROBLEM ONCE AND FOR ALL.....
GOT A CALL FROM A FORD DEALER YESTERDAY ON A F250
THAT DOES NOT VIBRATE.
VERY TEMPTING.
SEWELL CHEVROLET, NEW ORLEANS S U C K S !!!!
I really want a Chevy bad but refuse to have one that shakes.
Are the 4x4's really better about this? If so, maybe I need to try one. Could it be that a 4x4's ride is rough enough to mask the vibration?
One Dodge salesman told me the problem with Chevy's was due to shipping. Seems they pull them down too tight to the trailers and bend their suspension causing the vibration. If that's all it is, I'll go the factory and buy one from a local dealer.
Cheyy4me, did you ever find out about your rotor and is it normal?
I still have a clank when I put the truck in R, sounds like bad u-joints.
Z71 but my salesman says if they do, they will
reinburse me for the amount paid minus .25 a mile.
and for any add-ons left on the truck if I produce
receipts. Have heard that they will not do this too so don't take my word. Will be speaking with
Chevy again tomorrow, will try to find out then.
I think they stall everyone so the miles go up and
they spend less money or people just sell/trade them off as if they buy it back, it has to be
noted that it was if they resell it. To get the
ball rolling you have to call Chevy Cust service
and get a file started, they will give you a file
number to refer to everytime you talk with them.
Hope this helps and good luck.
I tested it over all the roads I normally got the noise and clunk on and the new shaft fixed it. It's like a new truck again....
There are many things that I really like about this
truck but, I have experienced a number of problems
with it. Vibrations, Steering Wheel Clunk, Sticky
Throttle Cable, Leaky Cab, Wind Noise, Bad Tires,
etc...I have perused all of the postings in the
topic list that relate to this particular vehicle
and there are a number of extremely common threads
that are very widespread. I think we all know what
they are by now. The Vibration one is a really
serious one that GM has started buying back trucks
that simply cannot be fixed to the owners
satisfaction. Has anyone entertained the idea of a
class-action suit? It appears that it would be
well warranted. The issue that concerns me is
resale or trade-in values. As all of these issues
leak to the forefront who do you think y'all are
going to get someone to pay fair market value for
what is likely to become a lemon model year??? I
think that as exposure widens it is likely that the
public may regard this entire '99' year of GMC
trucks as something to shy away from. Who do you
think is going to personally take the hit for
several thousand dollars when that happens???
Looks to me if these problems are as serious as
they appear to be we should all stick together
rather that fight our own personal wars with our
individual service departments and GM. Don't get
me wrong, I think this truck is a winner in most
respects but these issues are no laughing matter.
Do you really think this isn't going to make a
difference? Somewhere along the line it looks like
we are all in for a beating. Any class-action
takers?

Today I visited my dealer and he is initiating the buy back. He didn't provide many details but did say there was a deduction for mileage, but a reimbursement for any add on's. He is to call me tomorrow with further information. It is a shame that GM can't find a fix for this problem. It is a really fine truck otherwise. Just miserable to drive.
At least your dealer is initiating the buy back. I have also gone through five tires, leaf springs, shackles and bushings. Still shaking. I'm suppose to have another tire installed next week and I feel pretty confident that it won't be fixed. I will start the paper work for the Lemon Law (in Fla.). I agree, the truck is pretty sound but the annoying vibration is too much to deal with.

YES - It has the Launch Shudder in 1st and 2nd gear. Dealership replaced rear springs, bushings and shackles as per GM TSB. New springs solved the Launch Shudder when the truck is empty but not with a 650 lb. load. Launch Shudder was actually worse with the new springs and a small load.
Dealership sent the truck to a Spring Shop and had an extra leaf added. Again NO Launch Shudder when the truck is empty but the shudder still occurs with a load, but only for about the half the distance.
Although the new springs have decreased the Launch Shudder they have created two other vibrations that were not there with the original spring set. Now have an almost constant vibration/shuddering between 30 and 40 mph., very slight but its there. Also an inconsistent but very noticeable vibration/shudder between 50 and 60 mph. Feels like you're driving over 1" deep groves cut into the highway. The lower speed vibration occurs most of the time. The higher speed vibration only occurs occasionally and will stop when the throttle is backed off.
I bought this truck to tow a 22'- 4500 lb. 5th wheel. From what I've experienced so far, I hesitate to invest the money to install the hitch. This truck looks great, but for $38K (Canada) I doubt that it will tow a small tent trailer.
It looks like GM has dumped these trucks on the market without proper testing and is letting the Dealerships give the buyer the run around.
