Thread: D1 24 spline diff into RRC help

Okay so I did a bit of searching around thanks to Google and have found this list on discoweb.org
I hope this is correct if someone can please confirm that would be great

Rear:

DI Hubs
Spindles
1/8in washer (butts up against the outer bearing)

Rear also does not utilize the outer grease seal like the RRC hubs do. Rear can also maintain utilization of all stock brake components.

Front:

DI Hubs
DI Spindles
1/8in washer (butts up against the outer bearing)
Axle Circlip
Outer Axle Spacers/ shims
Axle Flange
Dust Caps
Front also does not utilize the outer grease seal like the RRC hubs do. Front can also maintain utilization of all stock brake components.

Also I was looking at changing the front diff to 24 spline as well as I have a whole diff there from a D1 but I'm can't remember what year it was so I don't know what seal kit to get so I was thinking of using the RRC housing and swivel hubs then using the D1 centre, axles, CV's, and stub axle but not to sure what way to go wit this so some help on this would also be great.

There is a serial number on the top of the axle tubes, this might help with what seal kit to use.
For my RRC I am just going to swap over the whole axle assembly, less mucking around.

But will the RRC calipers bolt up to the disco diff?

I recently did this swap on the front and wanted to use the RRC calipers. My Disco donor was a 95, the RRC is a 91. The calipers will bolt up fine, but you have to drill the mount holes to 12mm to use the Disco bolts, not much of a difference but enough. The RRC use an SAE bolt which is a bit smaller. On a drill press they will centre well enough. All worked out OK for me, no snags.

For those interested in this I have also found that you need to swap 4 of the studs for the diff centre (2 each side) for both front and rear as the RRC ones are shorter.
I have the rear all finished and am hoping to complete the front tomorrow as I'm just waiting for 2 seals.

3 months ago we put a front late Disco1 24spline diff into the front axle housing of our 1990 defender/ perentie. We got rid of the smaller 2 pinion original diff, thinner axles, smaller CVs.

Again, like you, the 4 diff bolts parallel to the axles, 2 leftside, 2 right side were too short because the disco diff lip is cast an even thickness all around while the defender diff is scooped out thinner on each side parallel to the axles.
