Control Arms
Hi all,
I thought I knew how to do a google search but I was mistaken! I have a 2009 LS 460 (Base) AWD and I can’t seem to find the control arms for my car. I have air suspension if that matters. All of my searches resulted in control arms for the RWD only... Lexus won’t give me the part # (obviously) and the prices are INSANE!
I am looking for:
1) a complete parts list for my car
2) best aftermarket replacement parts
3) both front lower rearward control arms
4) driver side upper rearward control arm
There is also a thumping sound in the rear... and was wondering if the airbag strut/shock has mounts or if the mounts are part of the unit... I know for a fact the airbag unit is good... not bouncy at all. And I can’t afford to replace the entire unit if the only thing is the Mount...
The best I can describe the thump is that it Sounds like the unit is loose and when I go over a bump the thump is the “play” from the unit being loose... that’s probably the worse/worst description ever!
Any info would be greatly appreciated and want to say thank you all in advance!

I've looked around a lot too. To my knowledge, nobody makes the AWD "strut rod" lower control arms or upper rearward control arms. I'm just wondering what the exact difference is between the RWD and AWD in terms of the incompatible upper control arm.
In these cars thumping is a classic sign of a failure with the air strut. The air strut is an integrated unit with no user serviceable parts.
In other cars, in my experience thumping has related to the strut mount and/or sway bar bushings.
If you end up needing to replace your rear air struts and are considering the ones on eBay, I have a pair that I never used since I decided to go to aftermarket coil suspension. Let me know if you may be interested.

I had the rear thump . just replaced all my struts with reconditioned struts. My ride has improved slightly but the thump is still present. That leads me to believe it's rear control arms , strut bushing or some other suspension component making the noise.
Surely my control arms are overdue so keep us posted on what you find.

Take a look at http://www.shopfigs.com/ they offer lots of upgraded suspension parts for all Model Lexus cars including the LS460.

You will only need the offset version arms if you want to increase you camber/caster, not needed for daily driven cars. No, they address the soft rubber bushings by installing poly bushings instead.

The front lowers are the ones I'd assume aren't interchangeable?
what front air struts or spring struts are available for the fronts?
And by the way guys stay away from PSB bushings mine failed in 2 months it was the biggest waste of $1000 in my life

Front spring struts are offered by FCS and Duralo that I've seen so far. The FCS quick struts are available on rockauto for somewhere around $100 for each. I bought the duralo struts but haven't installed them in the front yet.
Sorry about the PSB bushing experience. I heard they suck too!

The front lowers are incompatible but Beck/Arnley manufactures one AWD-specific front lower. The other front lower is a dealer-only part unfortunately.
