Suggestion = put your year and model in your signature, it helps to (after a few pages on the forum) to remember these details.

Did you swap wheels (side to side) to eliminate wheel or tire damage?
Did you remove the CV shaft - a bit more work but you eliminate this as well?
You could swap shocks (side to side) before buying a pair. I have yellow B6 on my E53, firmer but no regrets.

Having needed the replace my four rear axle carrier bushings, you'll get a clunk over speed bumps, imperfections, sometimes feel a slam sensation. Less intense with 17", more so with 18" (my two wheel sets).

It might appear to be "too soon" but the pothole might have done this. In my case, visual inspection didn't reveal or indicate damage BUT upon assembly - EACH of the four bushings came out in two pieces. My case was simply the march of time - it's a necessary item on the E53. The E70 design appears to be quite similar.
