polyerathane Bushings

Had my new alcon leaf springs installed. They came with the red polyerathane Bushings installed. I can see that they greaced them very well when installed the bushings into the leafs . Now that they are in the truck at flex I can hear the bushings squeaking in where they Mont to the truck. So my question is will they work them self in and quiet down or am I going to have to grease them between the bushing and the spring satel ? Any one ever have this issue and what was your experience?

 

I have installed poly bushings on other cars and yes they do require a lot of lubrication. The poly bushings should outlast rubber by quite a bit but like I said will definitely need to be heavily greased.

 

Yeah that's what I am hearing . I was hoping that it would break in and quiet down . I really didn't what to have to take it all apart to get lub in there . Thanks for your reply !
