Poly bushings

[Foreman72]

where do u guys have them and what have you see for improvements...since (i think) it should be treated as another suspension component, i intended to mix and match w/ some poly and some rubber...but i'm wondering what u all run and what benefits/drawbacks you've had...thanks

Do a search.  Topic has been covered often.

Drawback is they give a much harsher ride...

Point of view on that one Bryan since what one considers harsh, someone else prefers for the better control it brings.  In other words I don't find them to be a drawback on my car at all.

should have done and will do

its problaby mentioned in one of the other topics about this but typically the poly bushings for the lower control arms have tended to break or crack the k-member where the lower control arm attaches to it.  For this reason, most people seem to run rubber in that spot since it absorbs impacts a lot better than poly bushings do.

I'm not sure if that has been mentioned or not Brian but you do bring up agood point and that is most certainly a drawback.  Another drawback to a poly bushing there is that they are more apt to squeak in those rotating spots.  A lot of people (myself included) use rubber in the control arm bushings and poly in the sway bar and strut rod bushings.

Like you guys mentioned, i have rubber and poly. I just installed new poly sway bar bushings that are greaseable.

I chose to stay all rubber on my car where I could have.  The only exception was the factory sway bar bushings which they only repro in poly (and boy were they a pain to get in there too).

I can attest that when I had my Jeep CJ 7 and I used the poly bushings.  Even with the supplied grease, they still squeaked like hell.  Luckily I sold it and it became someone elses problem.

I think there's a lot of over-poly-ing cars just because people think of their 40yo stuff when they think of rubber ones.  Brand new rubber ones are not the same thing at all. 


Don't use poly on the LCA stuff even if you do use poly on the UCAs and everywhere else.  That's my biggest opinion on the issue.

On the rear end, it's a good slick setup to use poly on the shackles in back and rubber in the front spring eyeholes.
