Looking for any info on problems with the Chevy/GMC 2500HD 6.0L 4x4 front ends. I have a horrible vibration and noise comming from the drive side front end of my truck between 69 - 75mph. My mechanic thinks it's the torque converter???
Tires/wheel balance,and allinment are all good. Any other ideas from past experience here guys?

Ihad to have the steering shaft replaced on my 03.Call a dealer they may have a campaign out on it so no cost to you.

Both my 00 and 02 have had steering shafts at less than 30,000 mi. But was more noticeable at lower speeds.It made a clunking noise that you coul feel in the steering wheel.

I have that also.. You really notice it when truning at lower speeds. Every day when I turn into the parking lot at work I wonder what the clunking is?
now I know! It seems the shaft is loose? I wish this was my biggest problem though..

Hey Cap where you located? Never heard of Seneca? Up north? I'm 20min east of St. Louis

Take a jack and lift the fornt tires off the ground.Then shake the tire, if you have movement then its probably the wheel bearing. I've replaced 4 wheel bearings on the same truck within 30,000 miles, its just a bad design. Once you buy one, keep the receipt because they have a one year warranty on them. So if the other one goes bad than get it warrantied.
Its not that difficult to replace, a couple of tools and a couple of hours at max.
