So I started the 5 Lug swap journey this morning . I have an issue . Axles in with NRC brackets the caliper bracket is not even close to centered . I loosens up one side to show how much it has to come over . What do you guys thing ? Axles not in all the way ? Maybe moser didn't machine the stubs enough to sit all the way in ?

First pic shows how far the axle is still out with the c clips and pin in the diff .

Next is with the bracket right showing how off it is . Last pic how much Id need to space it to center it .

What do we think is the issue here ?

If your issue isn't the axle, then it is common to need a few shims between the axle bracket and caliper bracket to center it over the rotor. I had to do it even with factory axle brackets. Just on one side.

I definitely don't mind shimming it . I just want to make sure that's the fix .

Anyone else think the axle is out of the housing too far ? Or does it look ok

Found another pic of one seems the axle looks the same as in how far it's out of the axle housing

I've read that the NRC brackets do need shimming, but usually a washer's width. That looks like almost 1/2" of spacing you need.

What's the overall length of the axle you are using? 29.25"?

I thought those brackets were supposed to be "bolt on" and go. But, as with all aftermarket products, when you mismatch brands, they don't always play well together. I too have shims using the stock disc brackets, but I did the bracket flip too. As long as the axles seat correctly with the clips and pins, I would shim it and not worry about it.

Now, I did have to file the ends of my axles to have enough room to slide my pin in. Some aftermarket axles have more meat on the "buttons" of the axle end (that's a Joe term).

Yeah I had read that with the Mosers that's sometimes there was an issue getting the pin in . But I was able to push it right in with my finger no issue .

I had to go to work but either tonight at 3am or tomorrow I'm gonna pull an axle quick to compare .

These are supposed to be fox length for the disc conversion though ....

my moser 31 splines work fine with the drums, so they should be the right length.

the nrc shimming thing, as mentioned, is common. they probably patterned the thing on a flipped stock sn setup. looks like it only needs 1 hardened or maybe 2 normal washers though if that (dont know the size/pitch of those bolts, but looks like 1.5-2 threads?). make sure those are grade 8 or better (rarely see a bright finished grade 8, and the o.e. stuff is stronger and silver zinc'ed instead of the normal grade 8 yellow zinc)

8.8 . I have 10.9s I got that are a little longer so I can shim if I need to and still have the same engagement thread wise .

I'm gonna pull the axle out again and just double check the length.

8.8 is metric equivalent to roughly grade 5 in the SAE system. I'd run the 10.9 (roughly grade 8) or even 12.9 ifvyou can find them.

Yeah I just grabbed 10.9s . The ones they supplied may be 10.9s and I'm just having a brain fart .

Measured axles . Length is good .

Shimmed brackets with 2 washers on each side and a longer bolt . All good

Glad I had to do this anyway. The NRC hardware was 8.8 metric . I replaced it with 10.9
