2007-2017 Lexus LS460 RWD Control Arm Overview, Replacement, Upgrade Part 1

Instagram @LILEVO90

Lexus LS460 control arm failure and knocking noises are a common issue and complaint on these vehicles. Watch my videos and you can fix that! Some AWD arms are different than RWD.

2007-2009 (and 2010-2011) Lexus LS460 RWD CAN upgrade to the revised 2012-2017 control arms. Lexus does NOT advertise this.

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.
