Thread: D2 Diff into a RRC

I had this discussion a while ago with Daniel Bongard who is the engineer for Airlocker and compressors.

My discussion was in relation to running a Nissan Patrol HP into a Toyota LC60 axle housing (RD136 with Toy30sp side gears 728H111) and again in relation to running Toyota 8" HP into Rover (RD132 with Rover 24sp 728H141). In both cases the parts interchanged, so you just replace the sun gear (side gear) in the locker rather than broaching it. I would expect this will still work with a Rover RD128 and Toy30sp 728H111 side gears due to the unified gear sizes but best confirm with Daniel dbongard@arb.com.au who really knows his stuff and is super helpful.

Thanks..might come in handy

35spline 9" with long fields in rover housing??? Full custom I know, but

It works very well, LRA build the rear housing, its a Rover9 (they have actually installed a fair few into defenders aswell), its normally 31/24 spline, i wanted the comp locker http://store.arbusa.com/ARB-Air-Lock...-P22781C7.aspx and 35/35spline so had to get custom bits to let that axle through etc..its also a Pegged TruHi9 diff so epic strong and driveshaft is nice and high.
They are Hi Tough axles/Flanges as he was willing to make them and apparently they are the best due to thier elasticity.

Another option, depending on, availability of skilled help and how often /easy you would envisage bearing changes. Pull the unit hubs and machine up new hub with D1 / RRC/Defer PCD, broach and refit.
Unit hubs can be pulled apart carefully.

You may as well make the front match the rear😊
