While I agree with your thinking, AND I dont want to be the no no police, could there be insurance/rta/dot issues with the axle load rating going from a D1 to a 110/130???

I would like to know, on a well serviced diff, how many of these P38 types have "flogged out" the pinion bearings?

Yep, trying to get a sense of this too, hence the pegging question - i.e. if the bearings aren't a complete disaster, then maybe a bit of ring gear support in combo with a well set up diff would be sufficient?

Personally not very interested in a diff swap unless absolutely necessary.

Although maybe I should just get a plough and be done with it...

Rover,if your doing the type of off road driving that warrants an upgrade you get over the sals real quick,my Tdi had 255/85's on it,the TDCi has 235's and the 235's had 20mm more clearance under the diff even though the 255's are a much larger dia,like you said the sals is a plough. Pat

It doesnt take much to shave the bottom of the sals....

Yep, and it's dead easy to take 20mm off a Sals and add a HD cover without compromising anything.

If you lot don't play nice I'll be forced to post up another photo of my Brazilian :angel:

or bust out the checkbook and get a ruffstuff housing made to what ever diff center you want and all the rover fittings

like this you mean !!!

D1 and Puma 110 Axle housing same load rating, remember spring mounts are 1/2" closer together on D1 axle.

I posted up somewhere about the clearance and the P38 had something like 30mm more clearance over a sals even though it ran 235's and the sals had 255's.There's nothing you can do with a sals unless you run 35's and I'm over all that high lift/big tyres mucho BS. Pat
