The thumping occurs at highway speeds, 60-70mph as well as the lower speeds. Seems to go away a little bit when turning to the right. I wonder if it is somehow connected to the problem with the intermediate steering shaft "clunking". Perhaps some harmonic vibration? I just replaced my tires ($704.00) because i thought the tires were cupping and causing the thump, thump thump....sound. Like I said, it is intermittent, but can be extremely loud. Very annoying. I'll look for your response. Thanks.

mine is the same way, i greased the intermead shaft and it quietened it down some, but still there.

Hello i have an 04 gmc 4x4 sierra with 70000 miles on it at slow speeds like taking off or climbing a small hill at 10-20 mph i feel a rough spot in my pedals like a rough rub from something, does this going straight or in a curve, no load on it just creeping along and its not at the shift point, a couple of times it has even stopped for a split second,like it slipped then you feel it in the pedals then i hear some kind of noise like clunck from the rear end THANKS

I have a noise coming from the drive shaft area. Thought it was a disc brake squealer, turned out I was able to eliminate those. Sounds like it may be coming from the drive shaft center support bearing. Does this seem to you, that this may be where the problem is? If so what are my repair options?
