Put me down for a set, but if your still on the fence about it, I would like to see 7075 used on the spacers instead of 6061
I know alot of you guys want to weld in the retainers, but if retaining compound works, wouldn't getting the retainers made from 6061 reduce the machining cost dramatically?

There still needs to be clearance between the sleeve and the upper control arm ears or else you might just run a solid bushing rather than a spherical. I'm just using loctite 620 since thats what the sleeve was sized for. If the loctite fails the uca keeps it from being a catastrophic failure (IE wheel coming part way off and you crashing), but it would still end your day of racing.

When the rear suspension is assembled, are you sure the knuckle wants to move along the sleeve? In my mind the upper arm isn't taking any force in that direction, it's just supposed to be a defined length.

Ok, so there's clearance between the sleeve and the ears. The spacers and spherical are clamped between the ears and the sleeve is constrained on the bearing by the snap ring.

How could the wheel come off if the knuckle moves along the sleeve?

That's what I just said... "the spacers and spherical are clamped between the ears and the sleeve is constrained on the bearing by the snap ring[s]". We're on the same page on the assembly. I'm saying, what is the loctite actually doing? You think if you omit the loctite that the knuckle is going to move fore and aft on the sleeve? If you were to completely unhook your UCA... you just have the knuckle in the lower control arm... can the knuckle move fore-aft?

i can do 7075, i just wanted to do an analysis like bob did to see if its really necessary.

i think you read leafys post wrong, he said it cant come off in a worst case scenario since everything is captured.
