I have a 90 GS thats pretty much all stock. When I start my car in the morning and drive, its all good for then i start to feel this clunking come as I drive longer. It starts to get more harsh like the going up the wooden rollercoaster and only when its under load, pretty much at any RPM/speed but clunk rate is according to speed. If I park my car for like 20-30 mins, its gone and starts to come back again as I drive it more.
The axles look good, no rips in the boots, the mounts look good, didn’t find freeplay shifting the hub around… could this be tranny related?
