Adj. CA's Need lock nut?

[mikecooper]

I had rustys adj uppers and lowers until i got my tnt kit, and those bastards clunked after about 3 months. I greased them at least once a month if not more. Since ive had my tnt kit on i havent a single clunk. When i was under the jeep and pressed up or down on the ca's i could see movement. When i called rustys he said to ship them back and they would fix or replace them but it wasnt worth my time so i gave them away and bought a tnt kit.
