This SupraForums thread caught my attention since someone claims to have found a ball joint BOOT replacement for the SC/MKIV LCAs. Knowing that the LCA ball joints are non-replaceable I'm throwing it here for general interest... and scrutiny.

Edited for accuracy in light of further investigation-- At first I thought this might have been an actual ball joint replacement-- which it is not.

*To be clear to anyone new to the specific topic of front LCAs on 1992-2000 SC's, we generally recommend getting new replacements (usually spec'd for a 93-96 MKIV Supra) if not installing aftermarket bushings all around or if the ball joints are extremely worn.

That link is just for replacing the upper boot. Wrong link?

yeah that is just for the boot. unfortunately replacing the boot does not double the life of the ball joint.
It was replaceable on the mk3 but they did away with that for some reason not really sure.

Thanks, guys. My bad, then. I got my hopes up and it isn't what I thought it was. Changing the thread title to reflect this, or we can just delete the thread since it's not of much value... unless, Ali, you think an OEM replacement boot option can in any way help owners? You already mentioned replacing it doesn't extend the life of the ball joint that's in there. Perhaps it can help for the rare occurrence of a ripped boot?

I think its ok to leave it, the new boot does extend the life of the ball joint some by keeping it lubed well longer, but it wont double it is what I meant. its still helpfull if you have a ripped boot on a lower mileage arm, it can happen sometimes but usually the boot holds up as long as the LCA bushings last.

Someone should change the title of this thread to reflect the fact they're discussing the front and rear upper control arm in the SF thread.

Ok Ali. That's what I thought too (that they seldom ripped until the bushings themselves started to go).

blkexcoupe, thanks for pointing that out and thanks Ali for changing that.
