I'm currently in the process of trying to figure out what is causing a thumping in my front drivetrain. It started last week and has gotten progressively worse.
Things that have been worked on in the front most recently:
Upper/Lower Ball Joint
Clevish Bushing
Swaybar Bushing
Pass/Driver CV Axle
Intermediate shaft
Differential Gears and ARB service
When they put everything back together there was a bad vibration. Did the 500mi gear break-in and explained the vibration, and they proceeded to go through all the various parts of the drivetrain and tracked it back to the front driveshaft. It had been put back on, but not fully torqued which caused a vibration that increased with speed. They fixed it and all was well.
Currently, the thumping vibration is very noticeable in the 30-45mph range then decreases but can still be felt. It is coming through the floor and gas pedal, and cannot be felt in the steering wheel. It's in the driveway, on jack stands with the front wheels off. I have today and tomorrow off and would like to get this fixed asap.
I believe it's the drive shaft, but honestly don't know. Differential spins freely forward and back, and the CV doesn't sound like it's binding.
