I'd try this but, won't WD-40 deteriorate rubber?
Yes . You should not use WD-40 on rubber or plastics. WD-40 is a water displacing petroleum product . It will dry out and damage rubber and plastic . Better to use silicone, hard grease or mineral oil when lubricating around rubber or plastic . Exactly how bad would it hurt our bushings ? Probably not enough to worry about . More critical to smaller parts like seals and o-rings .
Thank you for the info Ill be taking out the bolts that hold the rear of the leaf springs in and will use a grease gun to grease it all up and put it all back in. I just hope that will help its getting worse :fs1:
