So I replaced my 79k upper control arms this weekend.



I followed this DIY and it was really easy.

The new control arms got rid of the clunking I had. I had replaced tie rods with OEM parts and still clunked, replaced sway bar enlinds and bushings and still clunked and last was lower ball joints with OEM parts and still clunked -_-

I used these because the OEM are soo pricey. Everything matched perfectly and even the nub on the arm is there.

So hopefully they last for a while.

Where did you end up sourcing those control arms?

From RockAuto.

By chance did the box or the arm itself show where it was made?

Yes, they were made in Taiwan.

is replacing the whole arm necessary? or can I just replace the bushings? also, my car is lowered on the OEM air suspension, should I go with a brand that's suited for a lowered car? and do you know of any?

I've never seen anybody just replace the bushings. Lexus doesn't sell the bushings alone I don't think.

Those look pretty crazy, I don’t need a drift missile. Also I’ve never heard of only swapping the bushings either, but the arm it self looks like it’s in great condition. My bushing are disintegrating though… 😬

The air suspension uses the same control arms? Why don't you look at Moog or Beck/Arnely arms like I used? There's also Mevotech.

Removed -posted in the wrong thread.

Is that LS 460 suspension?

It's been exactly a year since I replaced my stock FUCAs. I developed a slight clunk on the front driver side so I'm thinking the stock OEM fucas were fine to begin with -_-
The noise got louder during the Phoenix "winters" and now that were in the 95+ weather there's hardly any noise which leads me to believe I have bad front struts/top mounts. Good thing Bell Lexus is having a sale right now! lol
