Since this has no useful tech and has been covered previously I thought I'd post my rant in here.

This applies to the '93+ F-body.

I just took the front lca's off my car. I replaced the bushings in them with Energy Suspension bushings in the summer. Well after just a few autocross events the caster bushings on BOTH sides are ripped in half and one side had almost spit the bushing completely out. (The caster bushing are the rear bushing on the front LCA's).

I was mainly doing this to replace them as preventive maintenance. I had read where others had experienced a caster bushing failure and didn't want to take a risk of it happening mid summer.

I have a set of prothane poly bushings here. The caster bushing on these is completely different and looks much stouter-however I don't know what it will do.

Others have used the Moog replacement caster bushing sucessfully-use that if you're looking for a replacement.

Also from what I can tell the bushings have been shot for a while which might explain some ( not all) of my car's nasty behavior over bumps and dead feeling in slaloms. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rant2.gif) GRRRR.

My question is what did Sam's stock ones look like. His car is the same year as yours.....If GM added different parts on the same model and year of car, HTF are we to keep track?

In any event I'll be adding ProThane parts. While I'm sure that they will be MUCH more durable than the E/S part, I don't expect much more than 1.5-2rs.

It's quite possible that there were multiple suppliers for the bushings.

The original bushings have two holes passing all the way through to allow easier vertical movement of the control arms. At first I thought the Moogs just had shallower depressions, but that was just because there was still some paper-thin mold flash across the holes. The molded-in part numbers pretty much nail it anyway.

So, I wonder which will last longer - a fresh set of the stock/Moog bushings, or Prothane? Obviously neither is going to last forever.

I'm going to try Prothane for the camber bushing anyway since the Moogs are no better than stock. More importantly, the camber bushing isn't accessible on my press. After trying it, and repairing the damage, I gave up and removed the rubber core.

I already have the caster bushings pressed out, so I have until tomorrow to decide whether to install the Moog as-is or burn out a brand new bushing and install the Prothane.

My schedule keeps slipping ....
