The vibration in the steering wheel and gas pedal are nearly 95% gone. I got the same run a round from the dealers, "not abnormal, they all do it, it's the step tubes causing it". I'm retired and have plenty of time to make myself a pain in the a** at the dealers. Finally they put a short piece of flex pipe on the exhaust.....no difference. Then they "just discovered" a fix for the vibration from GM. They installed two vibration dampeners on the exhaust system. (part no. 10199232)
Getting Chevrolet to honor the new vehicle warranty that I paid for in the price of the truck is like pulling teeth.

1998 Silverado with vibration..... by kyhiker65

Hey all
 I have a problem that I cannot get fixed. I have had the vehicle to the dealer 3 times and they cannot find the problem. Here are the symptoms.
  When I apply the brakes, the truck starts bouncing in the front end. I have replaced the rotors and brake pads and the ball joints are supposedly good. Had them checked out the last time in, and I was told they are ok. I have bought new upper and lower to replace the old ones, but was told it would be a waste of money.
 
 So I guess my question is, should I go ahead and have them replaced anyways, and also have the steering link replaced along with the front end bushings?? Anyone ever come across this problem??? The truck has 190K miles on it and the ball joints are the originals, but I do grease them, along with the rest of the lube points, with every oil change.

When was the last time you changed your shocks?

I forgot to add that I changed shocks last year when this problem started. That was one of the first things I thought of. I put on some good biltstein shocks, and my old shocks were really not in bad shape.

2004 GMC Sierra 8100 (496) w Allison problem by andoverct

HI--I purchased a lightly used 2004 Sierra off of a GMC dealer about 6 weeks ago. It has the big block 496 and the Allison 5 speed and is very fun to drive and I assume that come camping season it will pull my camper effortlessly. In the last couple of days though I have noticed that if I lightly apply the throttle from a dead stop I get this minor thump or thunk. I have asked people riding if they have felt or heard it and nobody notices it. It is there and I certainly notice it---so my question is whether anybody else has this combo and notices it or whether it is "normal" with these Allisons. It almost feels like what a bad u joint would do...... I have also read alot about the torque converter bolts loosening on these trucks. Hellllllllllllllllllllppppppp I love the truck but don't want any trouble on a 4 year old rig with 40,000 miles.

It seems we may have the same problem, with no solution in sight. I have a 2006 1500 Z-71 4x4. When I hit my breaks and/or railroad tracks at any speed, I feel a slight vibration underfoot and in the steering wheel and quickly moves through the whole vehicle growing in intensity until the front-end tires are bouncing off the road and you feel like at any minute you could fly off the road. While you're in this bouncing around, I slow down to 25 to 30 mph to get it to stop. I've replaced front rotors and breaks, rear drums and breaks. I have 20 inch rims: they're 275-55-20 Perrelli Scorpions with "road force balancing." It's got 60,000 miles on it. It is at a point now that I am afriad to have my wife drive my truck because of what could happen. Fortunately, I still have warranty left, just a little concerned they will think I am crazy. Feel free to share ANY information, good or bad, that I can use to correct the problem.
