Need to change a rear u joint on a 1996 jaguar xj6
Undo the large hub nut with the car on the ground, loosen the wheel bolts. Jack and support the car and remove road wheel and the hub nut. Remove the large pressed lower tie bar that goes from the hub to the rocker panel. if you tap the drive shaft (dont damage the threads) you should be able to swing the alloy hub down and towards you. Using a decent wrench (the heads can round off) undo the 4 bolts holding the driveshaft to the differential, you might have to rotate and lock with the handbrake to get them all off, I allways mark the flanges to get them back to where they were aligned but this is not a Jaguar reccomendation!. you should be able to wiggle the shaft out. In a vice remove the circlips, with a centre punch or dremel mark the joint so it goes back the way it was made (verry important to keep the shaft in ballance) with the shaft held in the vice near the joint using a copper mallet tap the flange too and fro to move the caps out, when they are as out as far as the will go tao them all the way with a small punch, unhook the flange and then tap the spiderside to side and take the other caps out. The spider can now be wriggled out (if it has a grease nipple note what way it is facing) carefully take the caps off the new joint and place them face up somewhere safe. Slide the spider into the flange and push it to one side,slide the cap on to the end of the spider that is sticking out of the flange (this stops the needle rollers falling out) either push with the vice or carefully tap the cap all the way in and at far as you can so that the spider sticks out and put the cap on and squeeze it in with the vice. On the side that is still in too far fit the circlip then from the other side push the caps and spider across until the cap touches the circlip, this should enable the other circlip to be fitted. You are now nearly there! put the shaft in the vice, close to the joint, noting the correct alignment slide the spider in as far as it will go, place the cap over it and push it in as far as it will go, place the last cap over the end of the spider and push in. Fit the circlips as before, if a clip will not locate in its groove you will most likely have a needle roller out of place, no worry you have to take the caps off as with the old ones and replace the needle rollers with grease and go again. Assuming all clips are in the joint will be a little stiff, tap it about to seat the caps out to the clips and it will be right. Wiggle the shaft back in and replace the bolts, lift up the hub and start the hub nut, replace the lower arm but dont tighten. Tighten the 4 driveshaft bolts at tight as you can then jack up the hub so the weight of the car is on it (leave the stands in place) now tighten all suspension bolts, fit wheel and lower car, tighten hub nut very tight and wheel nuts.
