Default Should I replace my FCABs while I'm replacing my control arms?

I replaced my FCABs at 125k km (~75k miles), my car now has 195k km (~120k miles). However, this was done just over 6 years ago.

Now the outer ball joint on one of the control arms seems to be gone.

If I'm replacing these, should I do the FCABs again while I'm down there? Tie rods, too?
Anything else?

I would do the FCABs and Tie Rods at that point, they're cheap compared to the FCAs.
Maybe do end links also.

Agreed. Might as well do it all while you're in there if you plan on keeping it for a while.

BMW TIS says that once an FCAB is removed from the LCA it cannot be reused. I would go ahead and replace them.

Thanks, that makes sense. Probably easier to get the FCAB on with the LCA's removed anyway.

Now, do I go OEM again or something like Powerflex?

What about end links and tie rods? I'm slightly dropped, will the OEM ones be fine again?

I just replaced mine with Lemforders, cheap and they are fine. They just grind off the BMW emblem.

I went with the Whiteline poly FCABs. They are a PITA to install. So far so good, they seem to tighten steering response a bit and no noticeable increase in NVH. I've got less than 300 kms on them so far so can't comment on durability, which I know has been an issue with other poly FCABs.

Looks like FCP has a kit for what I need.
https://www.fcpeuro.com/products/bmw...e46m3cakitfull

All Lemforder with Meyle HD end links. Does anyone know if any extra parts are needed? Some bolts are one time use only I think and maybe clamps on the boots for the tie rod ends?

Don't mean to threadjack, but I don't want to clutter the forum with a new thread of my own.

I have a question regarding my rear control arms/trailing arms. My rear camber is really bad on my left rear. The camber adjuster is maxed out and I have crazy inner tire wear.

My question is, do you guys think it's just the RTAB or possibly a bent upper arm? Just trying to find a place to start for now. Subframe is fine btw, no cracks and nothing looks bent.

I still need to put it on an alignment rack hopefully in the next couple weeks to get some specs on how far out of spec my rear wheels are.

Thanks guys
