thump sound drive shaft
standing still at idle, when acceletaiong there is a "thump sound",(driver's side, maybe under rear passengers's seat.) one explantion has been a sliding shaft in the front drive components. (Vehicle is 4 wheel drive.)
It could be either the transfer case, transmission, or a crank problem. Any failures with any of those systems could result in a banging or thumping system. There is also the possibility it could be the rear struts but that would be more of a banging when you go over bumps.
I have had the problem 3 times and fixed it 3 times over a 130,000 mile period. Cost to fix- Almost nothing. The front end of the driveshaft has a sliding spline into the transmission. This spline goes dry and needs to be greased manually. Raise the rear end and make enough room to get under the car. Using a 12mm open end wrench, remove the bolts in the rear universal joint(keeping track of where they go back in, using chalk) and remove the driveshaft. On the front end of the shaft, clean the hollow end of the spline, and put several fingers-full of grease down in it, and make sure it is good and greasy. Reassemble the shaft into the transmission and reconnect the rear u-joint and the job is done. Mine reoccurred in 25,000 miles, so I greased it again. Permanent fix is to spend a couple hundred on a nickel plated yoke for the front end of the shaft. I prefer greasing the original one.
Chevrolet/GMC trucks/tahoes have had a problem since early 90s with trans. yolks sliding. Only fix is to pack with grease. I have 08 silverado. after braking feels like a bump from rear. The yolk slides out during braking. When brake is released the yolk slides or jumps back causing bump or slack.
It,s a drive noise sounds almost like it going in out of four wheel drive.
I got to put on the scanner. I think it,s got a bad speed sensor tell the processor that it wheel spinning

I hear a thumping noise in the rear of my car when I get ready to turn or accelerate in a 2005 Tahoe
I have a 98 Silverado z71 ex cab and when I hit a hard bump in the rd or have about 1000lbs in the bed my drive shaft rubs on my cab, it’s not a split/2 piece shaft it is a solid 1 piece shaft. What could it be ?
I have the exact same truck with the exact same problem. Did you find out a solution?
I have a 2006 chevy tahoe when I was driving I Could hear like metal grinding and than it locked up on me what could it be
try re squaring your trucks measure from middle of front hub to middle of back hub the should.measure the same and if one side is off just a tenth youll notice exactly what your talking about. best. of luck guys
