I have new replacement upper ball joints, they came in three pieces, the ball joint itself, a sleeve, and the dust cover. no instructions!! i have never installed these and would like to know how they are suppose to go together. i know the ball joint slips through the top of the control arm, the item i would like to know, does the mental sleve get placed under the arm then bolted together, and the dust cover go on last, or does the dust cover somehow slip inside the sleve and then it gets bolted on. i know this is long but i want to make sure before i tear this thing apart, that i will be doing it right, thanks steve
