Ball and trunnion boot replacement
You'll need a press,.. take the end plate off, then slide the big outside thingy back, being careful to catch the little caps on the ends of cross shaft, then carefully (without losing any of the needle bearings) slide the balls off the cross shaft.. The cross shaft is then pressed out of the driveshaft. Pull the trunion off the driveshaft, clean everything up, and assemble in reverse, being absolutely sure to centre the cross shaft, and be aware of any very small shims behind the balls, and the end pieces.. grant
