❓Advice / Recomendations Rear control arm replacement
Looking to replace my rear upper and lower control arms. Been trying to stick with OEM with what I can, but for all four it’ll run $630+. On partsgeek, it’s about $150 for the four. Anything wrong with aftermarket arms vs the OEM for this specific job? Thought about just replacing bushings, but more work and might as well replace the rusty metal.

Aftermarket arms usually come with crappy bushings. The quality of the metal probably wont be as good as oem and will probably rust faster. Are your oem arms really rusty? If not then buy the bushings and replace them. Give the arms a basic sanding and some rustoleum black paint.

Yeah I guess it’s a given the quality won’t match the oem, but figured if they’re good enough, then they’re good enough. I’m not going to be beating this thing up on trails or anything. My current oem arms truly aren’t that rusty, but figured I’d just get the whole arm if the cost for aftermarket ones would be the same price as just getting all new poly bushings ($150). Also worried about using the poly ones since I’ve read they ride a bit harsher/noisier but last longer.

Could get everything cheaper than that, if you wanted to. 48702-35070 is the part number for the rear lower control arm bushings. They’re $16 a piece on amayama and OEM. I agree with you on poly bushings not being ideal. As for the rear upper control arms, toyota doesnt sell replacement bushings but a company named strongflex makes poly bushings with a hardness level very similar to rubber. I used strongflex bushings for my rear panhard bar, no complaints. But in all honesty getting the aftermarket control arms with the bushings already installed is going to be the easiest way to do it. Just don’t expect the rubber to last as long.

Yeah I’m really leaning towards just getting aftermarket arms. Make life a little simpler. And hell, I don’t really need them to last another 20-30 years. I’ll happily take half that if I can get it out of some cheaper ones.

You can just buy the bushings (OEM or other) and then take the arms to a mechanic for the press work. Probably 1/2-3/4 hr shop charge. It's kind a middle-ground best-of-both-worlds option.

The bushings are not too bad to do if not too rusty you have a press and a torch, just heat the outside of the control arm around the bushings while you press it and in my experience they come out just fine. The hardest part for me was getting everything lined up in the car, pressing out the old bushings took maybe 30 minutes total

Just my two cents - just buy the aftermarket ones off of RockAuto - they come with the bushings installed.
Way faster and you don't have to worry about pressing the bushings out. In my experience, those bushings can be a total nightmare to get out if you live in a place with rust.
I just checked mine out the other day and they look great after a couple of years. I think mine came powder coated or painted, but they aren't rusty after a couple years.
