Found these on amazon: http://www.amazon.com/1990-LEXUS-LS4.../dp/B004DZ4N6U

At that price, are they probably very poor quality? Anyone have experience using them?

I believe I'd read threads about how these Arnott UCAs start to go out relatively quickly compared to oem UCAs.

The car has 375k miles on it. So if they'd last until we find another car, I'd be happy vs. the $700+ OEM cost per arm. Just don't want aftermarket ones that might break if you hit a pot hole or something.

I've read where some only lasted a couple months til problems started. If you search this forum you will find all kinds of bad reviews. First thread that comes up; https://www.clublexus.com/forums/ls4...nott-ucas.html If you're just gonna sell the car then it would be up to you about using them. But if you do, then you put the next buyer in danger of them going bad. I'd hate to have that on my conscience if something happens.

what's about this? http://www.amazon.com/Dorman-520-459...1990&carId=001

Sounds like a lot of the comments center around bad ball joint seals/boots that tear and let dirt in. I'm thinking a set of urethane boots might do the trick if they are available.

there's also the fact that the ball joints are manufactured with the wrong angle in the pin...

That UCA is from Dorman sold on Amazon by Amazon.

We can see here on CL that Arnott is no good. I am not sure about APX. APX is just a reseller and they source the arm from DMA Goodpoint. I called DMA Goodpoint and they no longer sell the arms (as of two months ago).

My guess is Arnott, APX, DMA Goodpoint, are all resellers. They all sell the same crap from China with the bad ball joint. If you go on Alibaba.com you will find you can buy these arms by the 100s or 1000s for very very cheap. My guess is all those arms on ebay are from this source in China. All crap.

Dorman may be different and better, but I am not certain at this point.

I searched and have not seen feedback from CL members about Dorman UCA. This is strange because the OEM is so expensive ($600) and I thought by now we would have some feedbacks about Dorman.

I called Dorman tech support directly today 800-523-2492 www.dormanproducts.com (1/9/2012). The man on the phone told me they design and engineer this part and they are manufactured in Taiwan.

The fact I got a real tech support person to tell me this gives me some comfort.

I will probably buy one Dorman arm and try it out. At $195 I think I am will to give them a try. (And Amazon.com will take it back if I tell them it's crap.) This product is also sold on rockauto.com.

Dorman part no. 520-459 and 520-460 (L and R upper control arm for first gen LS)
