Hello guys,

We have the following:
2012 LS460 AWD (Base)

Could someone please direct me the correct parts number?
Right front upper control arm. (there's 2 upper ctrl arms per side - are they the same parts number?)

We were thinking of ordering it from Amayama

You will want to be certain to get the updated model arm. So be very certain about part numbers you use.

Do you know what the parts numbers are, so I can properly search?

You can search the forum. Lot's of discussion and suggestions. "new control arm" Look at the sticky threads for FAQ.

Right upper front forward - 48610-59145
Right upper front rearward - 48610-59125
Left upper front forward - 48630-59145
Left upper front rearward - 48630-59125

Please, verify the part numbers with your local dealer.

Thanks for the information and I will verify before ordering any parts.

By any chance, would you know the updated lower, front control arms part numbers for an 2009 LS460 AWD?

Thanks in advance.

As far as, I know only front lower rearward control arms are different on 2013+ AWD. However, they fit on 2009+ even though the Lexus catalog does not say so. I have such arms installed on my 2010 and they are identical to previous ones except, the busing is stiffer.

Front lower rearward 2013+ AWD arms:
Left - 48670-59025
Right - 48660-59025

Please, verify with your dealer before purchasing.

Thank You.

Do you notice any difference in ride harshness or quality with the stiffer bushings? Does it have better steering response since the stiffer bushing would not deflect as much?

The steering and suspension are a little firmer over bumps. Otherwise, I haven't felt any difference. I personally like 2013+ front lower rearward control arms better than 2009+.
