Thread: are D2a diffs the same as a defender and or P38?

All Disco2 diffs are regular Rover diffs. The P38 diff is associated with the 4.6V8 which was in the NAS market - we didn't get them.

I checked with Tusker re the TD5 Defender 110 diffs, and his was Rover front (not P38 ) and P38 rear.

1 If vehicle was manufactured during 1993, check spline count.
2 Air Locker not available for vehicles equipped with high load option.

P38A was not used on North American delivered Discoverys - use RD128.

To make things confusing.....

I'm 99% certain all Aus spec D2's are Rover front and rear and that there were none delivered with P38 rear diffs. The ARB catalogue has had that printed for years.

Well if this helps i put a Series 2 disco diff with locker in the front of my old Tdi Defender
And then my old defender diff went in to the front of the disco

I'm with you there Simon, I believe the only d2's that had those were the 4.6 ones supplied in the US

Pete i think ARB says that the NAS discos (even the 4.6)use the RD128 in the rear. the US had never heard of the RD138 that ARB rec for AU discos
