After some online research, I called Lexus and they confirmed that they only sell it with the knuckle. Price for the knuckle is 400-500 for each side. Has anyone found where I can purchase the ball joints separately? 09 and higher seem to sell seperately just nothing for 07-08. Would the 09 fit in my 08?
boughtnmine from amazon... good luck finding them....

Seems the easiest way is to replace the knuckle with ball joint all together.
Question is, if its easy to separate the knuckle and the wheel bearing & hub. If they are seized together then the wheel bearings may need to be replaced as well.

Post #1 has no pics. It would be nice if original poster can upload the pics again.
I bought the cheap chinese aftermarket no brand from amazon ($40 a set) and could not get them to press in. I gave up when I found out the diameter of the ball joint is 46.1xmm while the bore on the knuckle is 45.9xmm. No amount of heating of the knuckle and freezing of the ball joints would make fitment possible, right?
Dorman makes them. Part number is 539-846.
febest makes them. Part number is 0120-USF40F
moog makes then. Part number is K500472.
SUSPENSIA X30BJ0595?


Anyone has diameter measurement of them before I order them?

Here, if the ball joint diameter is not anything near 46.0xmm, don't bother installing.
Amazon has a lot of Chinese aftermarket ones for dirt cheap and fast delivery but chances are, they are a waste of time.
