mixing poly urethane and rubber

5 lugs don't get much love.

I'm rebuilding my front end and the upper and lower control arms are getting rubber bushings replacements, but i can't find anything for the radius arm. I did however find poly urethane replacements.

Am i gonna have issues moving the two?
I've searched but I can't find a definitive answer.

 

There is a 5 lug section here.

I don't foresee a problem. Never have used poly there but I imagine the same results as using them other places. More shock felt when hitting a sharp bump and possibly a squeak.

If you can't find rubber I guess it will have to do but I kind of swore off poly a long time ago. I like cushey on the street now. Race car......yea, poly is good.

 

I have pretty much the same opinion as cruxofthebisquit on this...

That rod doesn’t do much. Its just there to stop the LCA from sway back and forth. So it doesn’t matter what kind of bushings it has. It will act the same. Only thing is the poly ones will sqeak if not properly lubed.


Also OP you got the links for the parts?

I don't have personal experience with poly bushings in the taco but other rides I have/had would only stop squeaking when I lubed with a PTFE or Teflon based grease, like super lube, etc. for the poly bushings. Bearing grease or petroleum based grease didn't work for me for quieting the poly bushings down.
