I have a '08 Rubicon Unlimited and got the 4" ProComp lift with the ES 9000 shocks.
Every time I put it in the dirt it starts creaking something fierce.
Even parked, I can rock the Jeep from side to side and it creaks like crazy.
Took it back to the installer a couple times and was told it was because my lift has Heim Joints instead of bushings and it's the Heims that are creaking. They said it was normal for Heim Joints and to just be sure to hose them out after every trip.
This just sounds like crap to me.
Does anyone else have this lift or this problem?

 

i may not be an expert. But i had hiem joints on an old XJ and they never creaked, even when dirty. BUT you have to realize that when you lift a jeep and put bigger tires on it, it adds more stress to everything. most jeeps ive driven or wheeled with have had little quirks. whether it be creeking or popping.

 

Have you checked the shock bushings? PRo Comp along with a few other companies got defective bushings for their shocks and just before they completely fail they start creaking, when they fail you'll hear clanking. We had that problem on the MX-6 shocks, had to change almost every bushing over the last 2 months

 

check your front track bar. Grease it up real well.
Mine did the same thing. I have to grease 'er up once in a while.

 

I have the 4 in pro comp with the mx-6 shcoks. I had to take my JK back after i got home because the shock bushing had crumbled and fell out. They have alot of the kits with bad bushings and the only way they know they are bad is after the install and the customer drives off amd then returns. They replaced the bushings and everything is coool know.

The creaking noise i have not had a problem with. I have heard that when u replace springs on a veh and u dont place them correctly that they can creak ??? not sure if thats the problem.
Has anyone ever heard that ?????
