Rear Upper Knuckle Bushing Replacement - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

There are no service parts for the rear knuckle. GM service procedure is to swap out the entire knuckle assembly, which is NLA. I had some lateral slop in my rear knuckle bushing, so I began searching for a solution. Someone on Facebook suggested I try a bushing specified for a Jeep, which was a remarkably close match. I pressed it in to the knuckle without issue.

The bushing I used is MOOG K201552, cross-reference to MOPAR 5105272AA and others, used in Jeep Liberty.

The major dimensions of the Jeep bushing match the OE GM bushing exactly. The only difference of note is the lack of flange on the Jeep bushing, but the only appreciable difference that causes is more care is required when pressing in the bushing to not overdo it.

I used a tool rental ball joint press from my local Autozone to press in the new bushing. No issues.

I then sent the car sideways. Bushing is holding up fine.

The Jeep bushing isn't specified anywhere in the literature whether or not it's a spherical bushing or a conventional bushing, but some product images from Moog suggest that this is a spherical bushing.

I don't understand why the aftermarket hasn't jumped on making a replacement, this i going to be a sort after part I would think.

If it articulates with your fingers it is a spherical. Does it?

It looks like a spherical.
