So after I installed my RS9000's I began noticing a "clunk-clunk" or "squeek" everytime the rear hit an expansion or pavement joint in a parking lot at slow speeds. I found that the bushing sleeves on the shocks were of a larger I.D. that the stock shocks. I had snugged the bolts down good but didn't want to over do it and crush the brackets against the shock bushings. This allowed the shocks to move up and down in the bracket as the bushing was larger diameter than the bolt passing through them. Tightened the rear shocks up TIGHT and noise went away and hasn't returned since.

Forward a couple weeks and I began hearing a noticable "clunk" in the front suspension when I hit bumps at slow speeds. This noise sounded a lot like the old steering shaft noise (mine has been replaced per TSB). Got to looking around and thought I'd check the front shocks. Tightened the top and bottom mounts pretty tight yesterday and drove the 140 mile trip to the area I grew up for Easter holiday. Noise is gone. Didn't hear it once the entire trip.

Something to think about if you have the Rancho RS9000 shocks and have suspension noises.

mine fit fine, maybe they changed as I have had mine for a couple of years ?:confused:

I've never heard a peep from them. I also torqued to recommended specs. I didn't worry about the rear brackets as I knew they would bend to conform to the shock bushing.

i had a clunking noise from my front drivers side shock after install but after i tightened it some more i didnt have a problem. the thing i noticed is the old shocks (stock) had a metal sleeve in the bushing so you could only tighten it so much and that sleeve would contact the shock mounts and you couldnt tighten it anymore. the ranchos dont have that and i was afraid to overtighten them and ruin the bushing.

I have the same noise. Going to tighten them today. I installed the air to the shocks yesterday, all the adapters on the shocks leak. Did all the checks , now 3 leak. Going to call Rancho on Monday to see what gives

When I installed Bilsteins on the front of mine, I thought the GM rubber cushions and sleeve looked better than Bilstein's, so I used the GM ones. Worked fine, and it took the guesswork out of tightening the mounting nut.

I threw my factory shocks away when I installed the Ranchos. Wish I would have kept them now so I could swap the rubbers out. :cool:

No problems with mine.
