Need help on setting up a D30

I got a set of 4.10 gears from a late 80's XJ D30. They don't just drop in my 98' housing. I need to add shims to the ring gear side of the carrier to bring the ring gear closer to the pinion. I do not the tools to properly press the bearings on and off.

I have heard the shims from a D35 are the same as a D30. The difference is where they are installed. Between the bearing and the carrier on the D30, and between the bearing and the housing on the D35.

The carrier fits snugg in the housing but not tight, it takes no effort to put it in. Can I just add shims between the bearing and the housing to correct this?

I'm going to suggest that you take this somewhere to get it set up correctly....just based on what you wrote in your post and the questions you are asking.

I've set up gears before. I'm just wondering if the shims can be added on the outside of the bearing instead of pulling the bearing and adding them there.

IIRC, we did that when I helped my buddy set up his 8.8....but dont quote me on that...I might be mistaken. At the time, it was my first gear install...

Thank you for the replys. I will try it. I don't see why it wouldn't work.

Here's the D30 shop manual from the Dana site.

Correct me if i'm wrong.. i dont see how you'll get the shims positioned right. (i'm about to attempt my first setup)

The ID of the shims would be larger than the ends of the carrier obviously, now when trying to put them on the outside of the bearing the axleshaft OD will be much smaller than the shim ID.. i see the shims spitting out and probably deforming when installing the carrier.

Or is there a flaw in my thinking?
