use 90 axle in back of 110

In a 200tdi 110 would it be a problem to use a military 90 rear axle in place of the Salisbury.

The 90 axle in question would have the HD 4 pin diff and half shafts and the wider wheel bearing spacing being from a 1980's vintage truck.

I'm considering doing this to improve the ground clearance under the diff and because I have the 90 axle.

Think you'll need to lengthen the driveshaft from the LT230 to the axle......

No issue really, just a different lower spring perch that attaches/bolts to the axle housing. Years ago there was a study done comparing HD Rover shafts to Sals shafts, and regardless of vendor (at the time), the HD Rover shafts exceeded the strength of the factory Sals. Said study was part of a discussion between GBR (Bill) and Rover Tracks (Keith).
Hope this helps.

I have one in the back of my 110. No problems. I did buy a 1.5 inch spacer for the rear of the drive shaft. I like the 24 spline and disc brakes. I just installed a true trac locker. I will ugrade the axles eventually. But I'm very happy with the change. Should mention my axle came out of a 99 Disco one. But they are the same as a 90

Because that would be a lot weaker. The axle he is putting in has a 4 pinion, 24 spline diff and much stonger halfshafts.

The only real concern with the Rover axle is its weight rating. If you plan to have a heavy 110, you might be concerned.

To be clear on the subject... he is talking about the 23S rear axle, referred to as "Heavy Duty" by Land Rover and used in 90s with V8s and in most ex-MOD 90s. It used a machined body, 4 pinion, 24 spline differential and "heavy duty" halfshafts that were bigger and stronger than the later model shafts.

For some reason they didn't use the 23S on the US 90's.

Why not just use the disco axle (with disc brakes) and pop in the 4 pin HD diff (straight fit) and the V8 HD shafts (as per camel disco 1's)

Best of both worlds then

The early halfshafts are the wrong length for the later model axles.

I did this in my RRC but as Red90 notes the HD military shafts don't fit so it has the Disco stock shafts with the HD diff.

^^^^ Hmmm maybe for really early axles, although I didn't think the track width was much different?

I /thought/ I'd put a 4 pin & 24 spline shafts into a drum axle... maybe it was later disc... old age getting the better of me now haha
