Default UCA problem

Hey guys I have a 2000 lexus gs400. I need to replace my upper control arms both the right and the left side. I was wondering if you guys can help me with some good websites to buy the UCAs, thanks

If you want to go with stock design you can get them on RockAuto.com.

SPC makes aftermarket adjustable arms
Figs Engineering is in the process of designing a new arm
Ikeya? has some baller arms

n then you have OEM and the rockauto parts.

Why do you need to replace them? Whats wrong with them? Ball joints?

Ok i'll try to explain.. I took my car to 4 different repair shops and 2 of them looked at my car and said i needed to replace my UCA after they checked it out. The other 2 places did not see anything wrong with it. The thing is everytime I go up my driveway it makes a pretty noticeable sound when the front wheels hit the steep driveway. It happens everytime i go up something steep but not speed bumps. I'm pretty sure it's because im driving straight when i drive over speed bumps but for driveway i have to turn the wheel and that's what also contribute to the sound. Weird? I know. Its not the balljoint because it used to make another sound but its gone since i replaced the balljoints about 6 months ago.

Is your car lowered? If it is then you need to cut a hole where the control arm hits the fenderwell

No it's not lowered, pretty much bone stock. But I have 20' crome rims, it came with the car when i brought it so im guessing it's taking a toll on the suspension. See I don't know whether it really is an UCAs problem or the other 2 repair shops are just trying to scare me into fixing it.

I would do more investigating before replacing upper arms. Take it to another shop for diagnoses. I could be lots of things.

This happens when your lower ball joints fail.

^ Isn't this from ball joint failure? I seen that pic before

No way can a strut or upper strut mount cause that drama...
