polyurethane front control arm bushings. yay or nay
I want to start a post on this and get opinions on polyurethane bushings for the front upper and lower control arm.
It seems that a lot of users on here had squeaking issues and were not happy with the polyurethane bushings.
Its recommended to use a heavy-duty marine type grease to grease all around the edges of the bushings, anything that can squeak.
Is there anyone out here who is happy with the polyurethane bushings and doesnt have squeak issues?
Also, let me know if you used a heavy-duty marine type grease on the edges.
The bushings on my 93 c4 are cracked and in need of replacement soon.
I have an extra set of control arms with NOS rubber bushings in them and I am contemplating pressing these out to put in polyurethane bushings.

I put in Global West Del-a-Lum bushings in my '90. I no longer drive it one he street but they have a smooth quest operation. They do stiffen the ride a little, but I dont think that is a huge concern for you.

Are these meant for street use? I do still enjoy using my car for some long trips and such - though I avoid bad roads. Of course sometimes you can't avoid a bad construction zone or something.
I may still want some compliance. Id hate to hit a small pothole or something and bend suspension components or a rim.
Are my concerns valid? Of course I remember when I put in my banski rear suspension that eliminated all bushings back there, I expected a rougher ride. Instead, the ride got much better as road shock was transmitted directly thru spring/shock vs . Into the frane via my worn out rubber bushings
Do you feel like that's a risk?

I used the Energy Suspension Kit all around mine and I am happy I did. I still have all the stock upper and lower control arms. I also used the heavy duty marine grease and no issues with squeaking yet but I have been told by a few local guys here in my town that they will eventually sqeak overtime . With that set up you have which BTW is SUPER COOL, it may be in your best interest is well.

Delrin is an option I didn't think of.

Global West for me as well. Thousands of street miles on them without issue. Sure, if your drive into a 12" deep pothole you might break something....but you'll break something with the stock rubber bushings as well.
