Well, the failed ball joint has been replaced. Had to replace a the coil spring on that side as well. A piece, about 1/3 turn, of the coil had broken off at the bottom. Nervous job with only cheap MacPherson strut sping tools. Wound up using some 3/4 inch black iron pipe as a safety device. Slid 10" sections of it up thru the A-arm and the spring with couplers until it stuck out the top. made working around the spring less frightening. Supported the A-arm near the ball joint and just pounded the old one out with a socket and big hammer. Installed the new one by getting it started and then putting a socket under it and supporting it, then placing even larger socket on top of A-arm and pounding down to force the ball-joint up. Will have to wait to do other side. Need to work on my truck first-it is our spare car.
