I have my control arms out of the car for the pfadt bushing and new ball joints. I thought while they were out, I might as well add zerks fittings to ease in regreasing them when needed. Anyone have any pics of where they put theirs? Or suggestions on where NOT to put them? My luck I'll put them in a spot that will make it a PITA to get to.

I would not bother, I use Pfadt poly and if you put it together correctly & grease correctly use their grease it's good for a couple of years. After that you "should" be taking them aprt to inspect & regrease anyway.

For some reaon, the rear lowers are the only ones that are prone to drying out. The fronts stay loose for a long time.

Here's the front lowers after 3 years.

That's my experience also. I leave the rear lower on the stock rubber bush (the LG method) to keep it a tiny bit softer for some bite.

I'm not as worried about dynamic camber change on the rear.

In the whole control arm or just the shock bushing?

This video shows how much the arms move even with the Pfadt poly bushing kit.



And don't get me started on the whole forward bite rubber shock bushing thing.

I checked mine the beginning of last season, and they seemed ok. Went all season and didn't do a thing to them. Just dropped the suspension and they sound like an old hinge. Top seems ok, bottoms are really bad. I just ordered sphericals from pfadt.

The amount of hub movement is impressive, I never noticed it when I previously watched that video.
Does anyone sell a solid rear axle conversion kit for road racing? That should fix it and help with forward bite.

Poly's do need to be checked for lube, it's just my experience that they are good for a couple of years. YMMV

I see the movement at the end, but for a street/track car I think it's just a compromise that has to be lived with. Good video.

That's an awesome video... quite amazing these machines work as well as they do with all the forces they deal with.
