I recently installed only 4 of my poly urathane bushings from the kit and I noticed they make noise. (whatever) I was wondering if i should just grease them or if theres something i can put around them to stop the crunching?

 

you need to grease urethane bushings when you install them. some manufacturers also recommend that you regrease them once a year. noise is usually the result of not enough lubrication

 

I got the same problem. What's a good lube...WD40?

 

No mate, WD40 will just dry off quickly, you need preferably a thick grapphite based grease that lasts a lot longer, and will remain in place.

 

a silicone-based grease would be a good idea. WD-40 is not a good idea. you'll need to at least loosen the joints where you have the bushings installed and shoot some grease in there with a grease gun and needle attachment (can pick those up cheap at Autozone). You really need to grease the bushings during assembly though.

 

ok kool thanks man

 

Dont they make the black ones which are self greasing now ?

 

yes they have the black ones that self grease them self

 

The black ones don't "self grease them self" or whatever, they are impregnated with graphite, so they make less noise.

WD-40 is a penetrating agent, not a lubricant. Use the grease that comes with your bushings or get some from Energy Suspension...
