Polyurethane bushing squeak
What post #4 said & more......
Factory engineers are not stupid. Some cars have a full chassis with the body mounted on rubber biscuits to absorb vibration & road shock. These Mopar models do not have this extra layer of protection. Rubber bushes are used for good reason, to help protect the body from shock going over potholes etc.
Factory engineers are not stupid, I agree.
But, they also do not get the final say. Factory production choices are frequently dictated by cost. Rubber bushings are used by the factory because they’re cheap, and they’re soft enough to allow for looser production tolerances.
Replacing the rubber bushings with poly is not a bad thing, it can absolutely provide for higher suspension performance than what these cars had from the factory. But it does also require checking and correcting some of the factory tolerances, as well as using improved components elsewhere (like better shocks, etc).
Just saying that the “factory knows best” is a seriously flawed argument. No, those engineers weren’t stupid. But they weren’t building these cars for handling performance, they were building them to make a profit. And technology has changed dramatically in the 50+ years since these cars were designed.
No I would not. I would never use these scrap bushings, I suggested that for you all to do so you can promote the sale of your junk. Carefully read the post. Keep it going, If you read my first post on this thread . I new you would be on here in a flash. I just beat you to it. Write us a book, Better make it a Novel since I woke you up. God of all suspension issues. LMFAO.
I have nothing better to do at this time then to reply to a squeaky post. Maybe he has a mouse in his frame rail. A friend here just ask me, "If I smoke after SEX" ? I never looked.
Did anyone ever tell you the difference between a Buddy and a Good Buddy? Are you my Buddy or are you my Good Buddy?
I read your post. As usual, your suggestions are ignorant, uninformed, and mostly incorrect.
Your suggestion of adding a zerk to the eccentric wouldn’t grease the sliding surface in that assembly, so it’s useless whether you personally use it or not.
What it does show is that you don’t have the foggiest idea how that control arm bushing assembly even works, since you can’t identify the area that would even need to be greased.
