07-17 LS460 Control Arms All Interchange: Videos Inside
I hope this is an "end all be all" control arm thread. I read the others and they are kind of all over the place with different bits of information. Typically my contributions here are very thorough and detail oriented. There was some talk in another thread about pictures from Russia using revised lower controls arms on pre-2012 RWD models. I'm happy to report this is true and completely works.
2007-2009 (and 2010-2011) Lexus LS460 RWD CAN upgrade to the revised 2012-2017 control arms. Lexus does NOT advertise this. Maybe they just want you to buy a newer car?
1) The steering knuckle is the same 07-17. This is good news if we are going to start swapping different part numbers control arms. That tells us the geometry is going to be the same.
2) The front lower arm was revised from silver to the black painted version, per the TSB related to knocking noise when braking.

3) The original part numbers for this front lower arm are 48620-59015 and 48640-59015. The revised part numbers are for the 2012+ fitment and are 48620-59035 with 59055 replacing that one and 48640-59035 with 59045 replacing that one. Based on the TSB, Lexus confirmed that 07-17 lower front arms interchange, but websites only show the new part numbers as fitting 2012+. Beware! If you have a 2007-2011 there is a great chance that Lexus will sell you the old, original silver arms referred in the TSB.
3) Lastly, while there is nothing official, the same conclusion can be said about the revised lower main arms that only show fitment for 12-17. Original 2007 part numbers are 48620-50070 and 48640-50070. The revised better bushing versions show on websites as "only" fitting 2012+ and are 48640-50131 and 48620-50131. Beware! If you have a 2007-2011 there is a great chance that Lexus will sell you the old, bad arms seen in this video.
These are the part numbers you need to order for any 2007-2017 LS460 RWD, especially 2007-2011 since they all have the original bad control arm design.

My videos don't specifically cover the upper arms, but there are old part numbers of the upper arms as well. I'm unsure if the rubber or design as a whole was changed to improve longevity, but the part numbers above are the "2012-2017" revised P/Ns.

The new washer is part of the entire shaft. It doesn't move, rotate or come loose. So the whole thing is torqued to 107ft/lbs to the subframe like the original, and the rubber bushing itself twists and rotates with suspension travel. I'm not sure how the physics or dynamics work allowing the "washer counterweight" to improve rubber bushing life.

Did you set the proper torque under the vehicle load? If not, you should otherwise your brand arms will not survive for long.

AWD is harder to do also it requires alignment after front lower control arm change due to presence of adjusters on control arm bolts. For me, it took 2 alignments for a local Lexus dealer to get it right.
I am jealous of your garage especially the lift. I do everything in the driveway on ramps and jack stands.

Ah, gotcha. There are no caster or camber eccentric bolts so everything is fixed on RWD. Does AWD suffer the same control arm failures despite having different control arms?
The torque sequence is relatively simple. Both lower arms are torqued to the subframe at 107ft/lbs with the vehicle at normal ride height.

It was expensive even though I got OEM replacement arms from overseas.

AWD needs more robust arms due to heavier front and additional torque due to axles. From what I have seen lower AWD and RWD arms are not interchangeable. Only upper forward arms the same in both drive trains.

I was able to get them all new for $1483 through a combination of https://www.discountpartsmonster.com/ and Ebay sellers liquidating OEM arms.

Get on ebay and save those part numbers as daily searches. You will get emailed daily on new auctions. Might take a few weeks or months to accumulate them all.

You could also take this a step further based on all the data and say all 07-17 air suspension interchanges as well, and potentially the air suspension computers so there is a chance you could install the 12-17 air struts and the computer that "controls" them. I'm not at that point though to guinea pig it. I have all new struts installed with the 07-10 interchange part numbers.
