GS350 awd front lower control arm bushing confusion- offset0, offset+20,offset-20
 

2007 gs350 awd.Looking to replace lower control arm bushings. When browsing for the OEM part on lexuspartsnow, three options pop up:
OFFSET:0,REFER R/M
OFFSET:+20,REFER R/M
OFFSET:-20,REFER R/M

What does this mean and which one do i go for?

Never knew they came in different positions. But its great that you are replacing this bushing as these are common to go bad and usually do not look like there bad.

I would contact the dealer to look it up via your vin number

I'm not 100% sure about this, but I believe the different bushing offsets are used to balance the alignment side-to-side in terms of caster. If you don't have a caster mis-match and you haven't changed bushings, usually the standard (0 offset) would be the best bet. If you are unsure of what you have currently, you can try wiping off the bushings and looking for paint circles -- there is a color code to tell you which bushing you have and what the offset is based on the color(s) of the dot(s). I would also note that the stiffer (primarily harder rubber durometer value, I believe) bushings from the 2016+ GS-F and RC-F are bolt-on "upgrades" for the 3GS. Those bushings will increase steering feel somewhat at the expense of some NVH isolation, and possibly some increased steering effort. If you search for those part numbers, you should find several threads that talk about the pros/cons.

GSF / RCF LCA Upgrade (0 offset)
P/S 48075-24010
D/S 48076-24010

Two pro-tips: the torque values for some of the bolts are different depending on if you have RWD or AWD, and make sure that you tighten and torque the spindle nut when the wheels are at their normal ride height (i.e, lower the car back onto the ground if you are using a jack and jackstands), or you'll see increased bushing wear.

I just replaced my bushings with the GSF, both bushings seem identical. Is it possible that the left could fit on the right and vice versa on the other one?

Awesome thanks for the correction

That isn't correct, the OEM parts are different (and have different part numbers) for left and right sides. The Lexus parts website refers to them as "No. 1" and "No. 2", but they are left and right side specific. At the very least, the center metal cylinder is chamfered on one side and flat on the other. It is absolutely possible to install them backward, and folks have posted YouTube videos where they show installing the wrong bushing, and then later correcting their mistake.

Thanks for correcting me, like I said its been awhile
