Recently there has been a sort of groaning noise coming from the rear of the truck when driving slowly over terrain that twists the body. Finally figured out that the noise was coming from the rubber bushings on the Sulastics. When I sprayed some WD 40 on them, the noise went away for a while. Going to remove the Sulastics, lubricate the bushings and reinstall them. The question is; what sort of grease to use? As the bushings are behind the rear wheels, they will get sprayed with high velocity water when driving, so need something that is relatively water resistant. Also, if possible, would like to use a lubricant that will not attract too much dust and form grinding paste.
Any suggestions?

 

Summit Racing has some synthetic grease they use on poly suspension bushings. I think it is Super Lube. I've used it on my poly bushings. It is very tacky. It shouldn't wash out. It would probably attract dust and small boulders as sticky as it is but it may not migrate with the contaminates due to that tackiness. I may have to pull one of my sway bar bushings to see if that has happened.

 

How about graphite? I used that on the poly bushing in my Jeep. It was not a daily driver though but it worked great.

 

Thanks for the suggestions. Will see what I can find next week while I am up in the States.
