Brand New Shocks Squeaking

[Lewa1200]

Hi all, I bought a full set of Rancho RS5000's for my 2000 Mountaineer and have had em on for about 3 weeks now (I also replaced the 5th shock with a Monroe Magnum Axle Shaft Damper). I got a really pricey alignment immediately after replacing them myself. They are incredible shocks--and although they ride very firm, the ride quality is very much improved and cabin vibrations at high speeds have significantly decreased. The Shocktober rebate deal was an added bonus.


Only problem is that I hear a high-pitched squeak from the driver's side front shock whenever I hit a bump. I've read online that spraying silicon lube on the shock is a temporary fix, but I was looking for more permanent fixes to this annoying sound issue.


The Rancho RS5000's also come with a fancy red boot to cover the shock and protect it from dirt. The high-pitched noise doesn't really sound like it could be caused by rubber, though I could be wrong.


Thanks for your time. We all can appreciate a quiet ride haha.

It sounds like you need to contact Rancho, and see what they know, I am sure you are not the first person that this has happened to. I have NEVER had a shock squeak before.

Spray the shock bushings first and see if the squeaking stops.
Lube all rubber, especially the front sway bar frame bushings.

Thanks for the reply guys. Is silicon spray lubricant the best to go with to lube the rubber bushings/parts of the shock?
