Advice on install of moser axles

Good question, I need the same answer.

Thanks for the detailed post, more work involved in that than I would have hoped.

Is it worth test fitting the axles first, presumably if there is some clearance you can just leave the thrust block in place?

Next question, I have just ordered a Detroit TrueTrac centre, do I need to run a thrust block of some sort in that if I am using standard 2 piece axles?

I don't remember removing the thrust block on the two sets of Moser axle installs I did. I sent my original axles in and they made a set identical in length. Since the originals worked with the thrust block why wouldn't the replacements?

Stock axle shafts and bearings require the thrust block to transfer axial loads from one side to the other. They use a single tapered roller bearing on each side that only takes axial forces outwards, so needs the thrust block to transfer inward axial forces to opposite side. Don't know if the TrueTrac accommodates the stock thrust block?

On later Mosers, they use Timken Set9 unit bearings, which are slightly smaller OD than stock so not a press fit in the housing, with a pressed on locking ring to hold the bearing on the shaft. The bearings take axial forces in both directions, so they add a spacer between the bearing outer race and the inner seal to take inward axial forces, so need to have clearance to the stock thrust block or remove it.

IMO, the stock setup is superior to the Moser setup for hard cornering, but Mosers are better for drag.

Hope this helps,RD.
