let wife use car to go shopping today and when she was in the parking lot on the phone, she hit the curb on the passenger front and broke wheel and bent the arm that goes to the frame towards the inner hub, and i can not find anyone that can get this part or know what it is im talking about, and it is not the lower control arm, that one goes straight in towards motor from hub. closest this is rear wishbone is my best guess or trailing arm.. but i'm wrong. I can admit it, but i have stock wheels in the front and the passenger side is pushed a good 1 to 1-1/2" back than the other side. and not able to turn the wheel all the way over, also found out upper ball joint is starting to go out, any better/cheaper places to get a new upper control arm other than a dealer, or junk yard? dealer want's over $600 bucks. for the upper with ball joint.

Its called a trailing or caster arm, I just checked with Lexus Edmonton today and they want $300CDN. Sewell sells a pair for $220USD. You could get non-OEM upper arms from Rock Auto for about $165USD.

thank you guys..

Were you able to identify the parts you need?

I hit the curb one time really hard once because I was cut off, and ever since my car rides like crap and cant get get caster aligned I'm planning on replacing the ball joints, caster arm and both lower and upper control arms to hopefully fix the problem...

We recently purchased this 99 GS300. previous owner hit a curb real hard a few months prior and spent $1400 getting the lower control arm or arms? replaced and a used wheel, new tire, alignment. They perhaps failed to disclose to us the long term effect.
As you have, the caster is off you cannot align car properly due to that and the car wanders to the right. The alignment guy's computer (Hunter) says to replace one or both upper control arms. He suggested an adjustable upper control arm or ball joint only, if thats even posible.

(One interesting note is the wander wasnt there til well after buying car).

Now if you saw my other posts we have a bigger issue with the loud clanking so we'll see what new lower ball joints and tie rods do.

which part are you looking for?
