Bought mooseracing ball joints from Pratville powersports . Part #0430-0664 because they said they would fit. Guess what, negative. I installed all 4 without putting the spindles back on over the B J studs. (archery season here in Pa.) The ball joints fit perfect in the a-arms, but the next day when I tried finishing the job is when I noticed the diameter of the stud on these parts are bigger than factory. Ordered factory joints from Joyner USA. Guess I"ll be dragging a bid ol buck this year. Not happy, but I should have done a better job comparing the new against the old.
