Thread: Life of Puma Rear Diff's

I tried getting a kingpin kit and he wouldn't believe me it was 2wd until I told him which axle and quoted the model and serial, then all the info came tumbling out
He also had the kingpin kit, part of the spares package imported to support them.

I later fitted a D44 I had underneath her.

The old T98a Warner 'box had a near 7:1 first gear, real crawler stuff

Ah, sorry I thought it was an original 4x4 J3000.

My bad.

Still a big ugly yankee truck, though

Also the F9 casing has clearance issues on a stock vehicle,

This new diff will take our stock rover air locker and be 3.54 ratio, ie a bolt in upgrade but will require the prop to be shortened a little,

Dave

Dave,

This sounds very promising, I'll certainly be following with interest.

So apart from the shortened prop shaft there is a new pinion housing and all new internals including your HD half shafts ? Will your limited slip ATB be able to be used ?

Yes, new housing, new ring and pinion, takes stock rover diff bearings, stock seal and flange, uses rover (non P38) diff centre, locker , ATB, whatever, but with larger crown wheel bolts so the 10 holes will need drilling out to suit,

HD shafts are optional,

Dave what is the design based on? eg D44 etc? Is it also a low or high pinion?

Hi, it's not really based on anything, just to our design,

It's a low pinion,

They are a good material, plenty of hypoid offset (1.5") means more teeth in contact , chunky teeth and bearing are further apart than the P38 like the rover,

Should be quite strong,

Dave

Thanks Dave, I really love the work you're doing with Land Rovers - such an innovator.
