I've been noticing the ride comfort is starting to suck. It is very harsh over bumps, crashes and jarrs over expansion joints. Not like what it was when I first installed it a year ago. It seems like its only the rear shocks though, the front of the car seems to glide over bumps nicely. The rears constantly make noise and I can see the top of the shock (the rubber part below the 2 nuts) move up and down quite a bit.

Has anyone else noticed a degradation in ride quality? It's so bad now that I know exactly what lanes to be in on the freeway to avoid bumps. I have the rear rebound near full soft , bump is close to the middle of range.

 

Try more rebound, less compression.
Leaks? Mileage? Could be time for a rebuild.

 

Didn't notice any leakage last time I looked there. Probaby only 5 - 7k miles.

Is it normal for the rebound adjuster and top of the shock to move in and out a lot?

 

You might have a problem with that rubber bushing up there, I suppose.

 

Not sure if it will help, but you might try *resetting* the damper by closing the valves all the way and then setting them back where they were before.

The shaft shouldn't be noticeably moving up and down...that sounds like a top mount issue.

 

My left rear blew.... hopefully that doesnt happen to you

although being in california, id take them back to KW, have them look at them.
