Thread: D2 Diff into a RRC

Haha..will try to talk to the guy who did the rear custom stuff..also want to know what is the biggest axle cv you can fit in a d2 housing

Don't here a lot of issues with longfields in the toyota's. I'd contact them personally.

So if i can get the hub adapted to RRC, then i can run maybe a 35spline cv and axles to a 9centre

The single most major difference between D1 and D2 stud patterns is about the way the disc brake is mounted. On a D1 the disc is attached to the rear of the hub, on a D2 it slips over the front. To change the stud pattern would involve major engineering in making the brakes fit. Even changing over whole axle assemblies will involve relocating suspension mounts, costing valuable engineering $$$ which could be better spent on h/d components to suit the existing setup.

I'm guessing he has gone as heavy duty as he can with bolt in bits already. Time to go a bit further😈

I could be wrong in my recollection but, there should be more than enough material to drill the D2 disc for the larger PCD, then it will slip over the revised hub I mentioned in the same place and utilise the same caliper and mounts.
If worst case blank discs are not too hard to sort. I recall the D2 axle housing is wider so some fab work will be inevitable.

The rotor may have a large enough hub but the stock hub unit flange isnt big enough, you would have to get 4 used hubs to pull apart and machine up new outer flanges so you can re-assemble with new bearings and drill to RRC PCD with new studs.
An expensive exercise and really not worth the effort

I don't know that I'd get too hung up on getting a 35sp into the CV for a LandRover. You really don't want the outer axle to snap and I suspect that would become your fuse in that setup. The outer axle holds the D2 hub together with the bearing unit (unlike the Rover hubs) so if it breaks your wheel will come loose. I would expect 30sp into the CV to be doable if the star is compatible with the 30/30 Longfields. If you run the Rover setup, then you probably still want the outer axle to not snap due to the collateral damage it does when it breaks.

9" and 35 spline is what they run with 42's and 500hp flat chat on the rocks. To run that strength in the front I'm not sure that Rover is the gear you need short of one of those rare front Salisbury diffs.
