Poly Lower Control Arm Bushings VS Rubber
I first put my car on the road in 1997 - I rebuilt the front end at that time and had all poly except for the LCA's
12 years later i rebuilt it again - guess what was the only bushings showing wear? the rubber LCA's!
I went this time with a just suspension pivot shaft, since it's od matches the poly ( no need for an inner sleeve, and just re-used my old outers.
No squeaks ever if you install them correctly.
Here is the poly vs rubber, they will never come out, ever.
