Polyurethane bushings

Newbie rebuilding front suspension.
This maybe a dumb question, when replacing wishbone rubber bushings with polyurethane, must I use the metal sleeves that are in the the rubber bushings? I just don't think they will fit.
Also, is there a grease fitting I can use on the wishbone rather than the blanking plug?
Thanks,
Ken
 
If I remember correctly when I did mine i didn't use a sleeve on the front bushings but I did on the rear bushings. The front bolt's fit the hole without a sleeve but the hole in the rear bushings was larger than the bolt so I had to buy a sleeve to fit. Just as a side bar. I really hated the car with the poly bushings. The ride was very harsh, you feel every bump in the road. I ended up removing mine and put the rubber one's bsck in. Just my opinion, others may have had better luck using them.
 
Thanks bcbug.
I'm beginning to have second thoughts about the polyurethane bushings.
I've read more cons than pros. Well I already did one side so I'll do the other.
I did'nt plan on doing the rear, hope the car does not get squirrely on me
Thx.
 
Ployurethane good for raceing, rubber nice for road work.
 
I like the tight feel myself. I don't race but do enjoyed spirited driving on a twisting road. Not a daily driver,
but I could live with the compromise for performance if
need be.
Either way new bushings will make a world of difference
if the old ones are worn out.
:driving: :thumbsup:
 
and, poly bushings don't use inserts
 
I found the poly bushing to be fine on the street (for about 5 years...then it became a racer).

But what I really like about the poly bushes is the fact that they don't seize like the steel inserts on the rubber bushes do.

Note: If using poly bushes, use lube provided or buy silicone grease (you can get a small can of it in the plumbing section of Home Depot). Do not use regular auto grease.
 
Prothane bushings, World Wide rebuilt shocks and a front sway bar transformed my Sprite. Put me in the yes column.
 
Actually, nylatron or delrin bushings for racing, not polyurethane, which deflects too much. You don't want the front end hunting about and twitchy under hard braking -
 
Are Nylatron bushings noisey? I'd like to tighten things up a bit more than urethane for the street but not if things get noisey.
Kurt.
