camber kit issue

i just got the ingalls camber kit installed in the front and the back and got it aligned and everythings fine in that department. i got the polyurethane bushings and they squeak hardcore. i talked to a couple of mechanics and some didnt know why they did that cuz they said they were lubed fine. another said that polyurethane bushings are known to squeak....some squeak and some dont and theres nothing i can do about it. it dosent squeak in the back....only in the front. i was wondering if any of you guys would maybe have a solution to this and help me stop my squeak and if not...word to the wise (go with the rubber bushings instead of the polyurethane ones)
thanx

try spraying them with WD-40

You have to use lithium grease or some kind of water proof grease. I use Amsoil synthetic grease. WD-40 will last about 2 days.

It's something you have to live with.

i apreciate the help with the grease suggestion but theres no point now....my car was stolen last night. major bust
