shudder during acceleration

Asked by Mar 06, 2010 at 07:40 PM about the GMC Sierra 1500

Question type: Maintenance & Repair

My truck begins to shudder between 40-50 mph but stops if I speed up or slow down.  It rides rough before 40 and after 50 but not as bad as the 40-50 mph shudder.  It seems to come from the rear of the truck but I just can't tell.  I've had it to two different garages.  The dealership gave me some excuse that I wasn't giving it enough gas and it was "laboring".  I took it to another shop that was recommended and they've looked at it twice.  They've said it could be 1. fuel filter and tune up. 2. universal joints. 3. wheel bearings......But they just can't tell.  They suggested that I wait til it gets worse.  Any thoughts?

In my experience as a mechanic that has always been bad U-Joints, or a bent drive shaft that has caused the drive shaft to vibrate between such speeds. Personally I'd try replacing both the U-Joints on the drive shaft as it is the cheapest fix to try, and it has a good chance of being a solution. Hope this has been helpful.

i would say u-joints

I had a car that did the same.. I had to replace the universal joints. After that it stopped.

Thanks. That's what the mechanic said but he didn't want to take it apart and that not be the problem. Trying to save me money. I think I'll just take it back and have them replace the u joints.
