CVJ Installation

There's two ways that these can be installed: either remove the differential or remove the trailing arms. I removed the differential because I wanted to have the rear mounts boxed in and welded. Once you have the differential removed you need to take out the old hubs and axles and remove the springs. Follow the Bentley or Haynes manual for the proper procedure to remove them.  Once you have the springs out, hook the shocks back up. At this point I decided it was time to install KeenSerts in the trailing arms to give the hub/brake plate studs a nice firm un-strippable foundation.  This was a simple task with the jig that Rick Patton made up and is documented here.

Here are the repaired studs locked into the trailing arm.

I didn't even have to disconnect the brake lines to move the brake assembly to here

Now was the moment of truth........... a test of the new hub and axle. The first iteration of these CVJs from a couple of years ago had fit problems that required some grinding of the inside of the trailing arms. But these new ones are supposed to be a perfect fit unless you have some material left over from the casting process of the arms.

Make sure you do the test fit with the brake assembly in place

The CVJs come with three nuts: the non-locking one and two lock nuts

Use three 5/16-24 nuts to hold the hub assembly in place, slide the axle in and
 use the non-locking axle nut to hold the axle tightly in place.

Now that you have it in, turn off the radio so you can hear, then slide under the car, grab the inner hub and rotate the whole axle assembly and LISTEN and FEEL for any resistance, scraping, binding etc. If it feels good, repeat on the other side. I couldn't feel or hear anything but I did take one extra step.

I wanted to clean up the inside of the TA and try and grind these ridges down a little.
This is some wax that helps to keep things from clogging up
I used a flap wheel on a die grinder which did a decent job.

Now it was time to put the axles back in, re-install the differential and test the plunge reserve range
