Took my '05 in for alignment and the camber is out of spec on the right rear. Shop said it was not too bad but if I wanted to fix it I would need a lower control arm.

Is this correct? What do I need to adjust it?

Peacebay

Lexus makes three different length control arms to adjust camber. Since I’m assuming yours is out of spec in the negative direction you need a shorter right rear control arm with the length of 441.5 mm

Part # 48730-50080

runs about $200

I'm negative 2.2. Is this the one I need?

Peacebay

That’s the one

I just had my alignment done and the left rear is out by neg 2.0. I have air suspension.
They said it was probably the strut, but it rides fine and isn’t leaking. Do you think I need the LCA too?

Peacebay, what do you think?

I ordered mine from Lexus for $187. Will be in tomorrow.

Out by neg 2.0? That seems like a lot. So it’s at neg 4.x? Cause I think 2.0 is still in spec

Good deal. Very easy install. Keep us updated

Here is the report:

Air suspension is tough. If your strut is in good condition and not sagging then yes you need that rear arm. 48740-50050 is the part number for the rear left.

Thanks. That corner’s air strut has never been replaced as far as I know. It’s not leaking/sagging/rough on the road though. I’m at 185k mi now.

If I were to go ahead and replace that arm and then in the future need to replace the air strut, would I need to redo the arm again at that point with a different length? Or is it something that can be adjusted? I’m not sure what length arm I have now. Do they stock the middle one 446.5mm from the factory?

Peacebay

From what I understand the stock length is the middle.

You know what, that is a great question though about the replacement. Im not going to pretend I know about air struts, because the only experience I have with them is through literature. Only have hands on experience with coil sprung 400/430s.

I installed a set of the Megan adjustable rear control arms on my LS430. They worked well for me.

I had a similar experience on my 2004 UL.

I had it at a small local tire shop. I didn't realize that my left rear corner was leaking down and the tech didn't know it had air suspension. In their defense They don't usually verify the ride height as coil springs rarely have this problem. After I get the leak fixed I'll take it to the dealer and verify that the ride height in each corner is set correctly before they start playing with alignment adjustments. It's just something you need to be aware of with a suspension that adjusts each corner individually.

Also, if the corner is low and throws off the normal camber it eats a tire quickly. I lost a very nice Dunlop.

For the price I would buy a set of these https://www.shopfigs.com/v3/by-vehic...T/LS430CORMEGA then no worries down the line needing to replace again if you find your alignment out of spec. These are adjustable so can dial in to exact spec.

I was tempted but read that they used stiffer bushings. Do they affect ride softness? We love the ride as it is.
