What is the purpose of the reinforcement plate under the x-member? Is it a safety thing? I have been checking the diff and found that one of the yokes has some play in it. would new bearings take care of that or could it be something more complicated? How tough are the bearings to put in once the rear cover is off and the diff is on the work bench?
The hardest part was get the 250 foot lbs or whatever it was to set the pinion drag on the crush washer and about an hour of gear paint/shim tests. Getting the HD Carbon clutch pack springs back in was a mother too. The aren't called HD for nothing.
When you open it up you may find other issues. I found I needed a drain plug installed, cover gasket, the 2 posi clutch pack retainer clips were almost worn in half, new yoke circlips, and seals.
Then I decided I might as well toss new posi clutch, bearings, and gear ratio too while its open.
