I noticed a vibration while driving the car a couple days ago, since then, it seems to have gotten worse. Im still new to AWD (recently swapped) so im not exactly sure where to look or how to diagnose this issue...
It almost feels like its coming from the area under the shifter area or possibly further back but im not sure. I feel it while accelerating and on decel, most noticable on decel from a higher rpm (5k). I dont feel or hear it as much or at all when acclerating under alot of load. It doesnt seem to be RPM or gear specific and I dont hear any odd noises when engaging a gear (R or 1st) from a stop. I did notice that if I release the clutch quickly at lower speeds, I occasionally hear a metallic clunk and feel a shake/rocking from the drivetrain.
I jacked the car up to make sure the carrier bearing brackets and rear were'nt coming loose and they're pretty tight. I checked the play in the drivshaft and it feels soft on the carrier bearing closest to the rear which may be the issue. I cant find any markings in the exhaust to point the finger at for rubbing either.
What are the most common vibration problems on the 2g AWD setups?
What should I check?
How should I check the U-Joints, and carrier bearings?
Possible t-case, drive-shaft, or rear issue?
