Had those 88A red ECS poly bushings installed about 2 years ago (2 front, one rear). Lately, started to notice a clunk during shifts.

Went under and noticed I can physically move my diff up and down a bit by pressing it like under a bench press.

I don't remember these being loose. Rear diff was recently installed after a rebuild, and I did torque all bolts down.

Do these things wear in any fashion? I know the hole is oblong, but do remember it's orientation was horizontal to the ground (front-to-back).


EDIT: Well, further investigation shows the rear bushing is moving up and down within the cavity. Looks like the poly material degraded from possible heat? Time for a new bushing. Thought these things were forever haha
