I'm getting a clunk from the right front when going over bumps. I'm assuming it'* the strut bearing going south. Should I replace just the bearing, or both the bearing and the mount?

I'd double check the endlink bolts (just in case)

Personally.. I'd take it apart once. Do both.

endlink bolts?

swaybar links he is referring to, they could also be causing the knocking noise if one has broken

Ok thanks Toastie and Boosty.

While you're checking things...check the tie-rods ends also.

OK...

The endlink bolts and the tie-rod ends are in excellent shape. I'm just wondering if I don't have that sticky intermediate shaft issue since the clunk is on the right side. No clunk felt in the steering wheel though. :?

You'd feel/hear the intermediate shaft in the steering wheel while turning, so it'* not likely the problem. Does the car use strut cartridges for replacement, or the entire strut?

NAPA NS71685 is the strut for your SSEi and my Buick. So you tell me.
