I took apart my complete rear end. I was looking at the rear control arm, the front of it that bolts to the subframe and the rear that bolts to the hub. Im making some bushings for my car out of delrin.

1)The bottom hub bolt has a rubber bushing in there that seems very free, either that or it s a sealed bearing or soemthing. Is it supposed to be like that, and do you think it would be a good idea to replace those 2 holes with delrin bushings? I already have dtss eliminators

2) The rear control arm front inner mount has that link. Those look like they need to move very freely. Is it ok to replace the rubber with delrin? I'm not going to get this part adj aftermarket because of the binding issues I'm hearing. Im just going ot get the single bar that gets you in the ballpark range for camber

 

No. It's not actually rubber, it's a rubber cover on a spherical bearing. Leave the "dog bones" in place or put on individual camber adjusters. If you are concerned about binding, rather than Delrin use spherical bearings in the outer control arm pickup points.

As far as question #1, I think those are bearings you are referring to, not bushings. I wouldn't replace a bearing with Delrin.

 

Cool, they seemed like a sealed bearing. The only thing is I dont have enough money for rear outter spherical bearings.

Should I just leave the stock outter rubber ones, or should I go with delrin? How about polyurethane?

Is there anything wrong with using the dogbone for camber adjustment? RIght now I have the equipment to make those bushings out of delrin right now. Im pretty low on cash right now. Im tyring to figure a good way to upgrade the rear camber adj, and stiffening without suspension bind, on a budget.

 

Delrin is fine, if you have it and can make them, do the outer control pickup points. The dog bones are fixed in length, so they can not adjust camber, your only choice is to keep them or get the individual adjusters which replace the dog bones. The single adjuster is fine, if you are looking for a bargain get one used and save a few dollars. If you really wanted, you could probably make your own with a threaded rod and some heim joints, but buying a proven design would be a better bet.

 

So these sealed bearings are not serviceable? Oh well, they seem fine, but I wouldnt mind changing them either

 

Replaceable - yes. Serviceable - clean them off and apply some good grease.
