DIY: AWD Driveshaft Rebuild

If you decide you want to or need to rebuild your driveshaft hopefully this will help.
Parts needed:
3x SKF UJ10430 Universal Joint (8708.99.1510)
2x ANCHOR 6082 Drive Shaft Center Support / Bearing (8708.50.8900)
14mm wrench and socket
24mm socket
6mm hex
Cylinder carbide burr
Ball Joint or hydraulic press

Before removing anything mark the shaft, joints and flanges really well so you can reassemble it back exactly the same.
Pretty straight forward to get the shaft out. My flange bolts had some loctite on them so they were on pretty tight. Used my corded impact to zip them off.
Everything under the van is 14mm including the support bearing brackets.
Once the rear flange and centre supports are off the shaft should pull out of the transfer case.
Some fluid came out so you will want to have a catch pan ready.

My rear u-joint had already been replaced so I did not have to remove any stakes. Using the ball joint press was pretty easy. Only hard part has getting it to sit straight.
I ender up using a couple of washer to keep things lined up.

You can only push the joint so far. To get the cups out I had to use a chisel and tap them from the side and underneath. Then I grabbed them with some pliers.

Once everything is out clean it up real nice and get ready to press in the new u-joint.

Note the replacement u-joint has a snap ring. I found it best to push the first cap in a little extra so that the other side has more meat to get lined up on.
When pushing the second cap on the joint will bottom out on the snap ring. You should be able to snap in the second ring and then gently press the joint back so the both rings have equal pressure.

For centre and front u-joint I used a cylinder carbide burr to knock down the stakes. I didn't go to crazy with the burr and the ball joint press had no problem pushing the caps out.
This might not be even necessary as the caps on these joints can't be pushed out far enough. I ended up cutting both of these with a grinder.

I may have to do some of this work on my van; thanks for this writeup! I found a dab of grease on the garage floor directly underneath the driveshaft's CV joint, though I could not find any evidence on the driveshaft itself of a failure.

The "bearing" with the six balls is a CV joint, and it is used to accommodate rear axle upward/downward movement in a much smoother fashion than a U-joint provides. If perchance the boot has failed, unfortunately I may have to replace the entire driveshaft since those parts aren't individually available (unless I can somehow find a salvage vehicle with a low mileage driveshaft on it). Or maybe I'll remove the boot clamp and squirt some grease in there and see how things go.

For now I'll keep an eye (and an ear) on it.
