Ive been experiencing a rubbing sound that comes from the front passenger wheel. I took my car into a shop to have it checked out. They did an alignment and everything was in spec besides the front right caster.It is way below the spec range( Showing 6.4 degrees when it should be within 7.3-8.8 degrees ) and the spec sheet said to replace the lca bushing to adjust back into spec range.

So I need to replace the LCA caster bushing with a new one. Problem is the OEM caster bushing comes in 3 different offsets ( zero , -20 and +20 ) and when I called my local lexus dealer to purchase the bushing ( mind you its a special order part $113.00 ) they couldn't tell me which specific offset the bushing i need should be...

Im currently on stock 18" wheels that have a 45 offset. Im really trying to avoid going to the dealer and have the work done there, which almost seems like might have to happen if i don't figure out which bushing i need to purchase from them.

Does anyone know which bushing offset I need? I've been to two different shops and they couldn't figure it out.

 

20 minutes is 0.33 degrees. Replacing the bushing will not get you into spec. Something is likely bent/damaged on your car. It may be the bushing, but it's likely something else.
