Perhaps the vendor that built the truck could come on and let us know exactly what is on there...

It's quite possible...I have that combination

It is not impossible, but someone adding a 1988- RRC axle to a 1997 Defender replacing the Salisbury would be a very, very strange thing to do, especially with the boost alloys.

Since its a 97 110 in Canada (of course), and assuming it was imported in this condition, I just want to assume its 24 spline. Its not that hard to figure out if you are willing to pull off the wheel and pull the shaft itself.

Here is a picture of the two side by side

He does not need to pull any shafts. The 24 spline, disc braked axles have integral flanges. Very obvious from the outside.

as does some of the 10 splines . They are different looking than the 24 spline having a more protruding flange but integral as well .

Ok, clear, Red. Now I just have to figure out the gear ratio and then decide if that is the ratio that I want to go with on the long run. I see there are some gear ratio calculators on the web. I'll have to see what it comes up with. I think my tires are 31". Any suggestions on the ratio to get or how to figure out the ratio?

I will take some pictures of the flange tomorrow and then hopefully you guys can see what spline number it is and then I have to figure out the ratio.

Unfortunately the vendor had no idea what kind of axel is under my vehicle....

They all came from the factory with 3.54, so there is a 99.9% chance that is what it has. With a 300TDI, there is little reason to change unless you were doing fairly extreme things to the truck.

Your registry entry says 285/75, which are 33" tires.

I would be more concerned with figuring out what strange things have been done to the brakes. Might want to see what brakes are on the front. If they swapped an axle there as well you could have smaller Discovery brakes.

Ok, that is good news. I don't often do anything that extreme with it. I do trailer boats and occasionally do expedition type of stuff where the truck is loaded up pretty good. So I am wondering what the pay-load of the Rover axel is compared to the Salisbury or P38.
I'll take some pics tomorrow morning and show you what the flanges look like and the front brakes. I definitely think the brakes have an issue.

So let me ask another question: if the axel is a Rover 24 spline, 3.54 axel. And I use it at times fairly heavy with the truck loaded up, with 33" tires, and I would put a locker in. And I plan to drive this truck for the rest of my life....

Would you:
A/ just replace the broken bearings and ad the locker to the Rover axel.
B/ replace broken bearings, ad locker and upgrade drive flanges and short shafts
C/ replace broken bearings, ad locker, upgrade drive flanges and short shafts and crown and pinion
D/ get a new P38 axel with a locker.

I am trying to figure what is best in the long term. I don't want to do a bunch of work on it and then still have problems down the road cause the axel is too light. On the other hand if it is really overkill to upgrade then good enough is good enough... As I don't have any experience with driving Defenders for that long and that hard I am not sure how things will hold up over time. ..

Cheers, and thanks!

A Salisbury is certainly a better place to start. It has a Dana 60 center. You would not want to do the P38 axle as it is not really any better than the rover.

For what you are talking about the Rover axle should be fine. With a locker, shaft and flanges they are fairly strong.

Thanks Red, I am going to do some shopping around for those parts. The full Salisbury axel is going to be too expensive... I'll post some more pics of the truck flanges later when it is light and warms up a bit here -22 C ! Cheers.

Ok, guys, here are some more pics of the drive flange and axel and brakes. It sounds that it is a Rover/Disco/D90 axel. Probably 24 spline? and then the ratio would probably be 3.5? If someone could confirm that for me then I would not have to pull the shaft/cover. Have to be sure though...
Cheers!

Looks 24 spline but your only 5 bolts and a bit of silicone away from seeing for yourself .

Yah that is the late model Disco/D90 axle.

So all late model Disco axels have a 3.5 ratio and 24 spline?

I also understand that if I want to replace the wheel flanges for heavier duty ones then the booster alloys won't fit?

It is all getting a bit clearer for me though. I'll make some calls on monday and talk to some of the suppliers. See what it is going to cost me.....

Ok to give a little bit more insight in this defender. This defender comes from Michael. Aka riverhouse. He rebuild this defender on a galvanized chassis. Its a sweet rig. I think your brake issue is you need to bleed the brake lines might be a little bit of air left after the chassis swap. Also for uiur axle i would not spend a lot on a new axle just rebuild this one with heavy duty flanges etc drive it for a view years.
Learn to get to know the defender first before you spend a lot of extra $$$$
Ps you don,t need a airlocker cause i have to pull you out when you get stuck.

Cheers your friend jeroen with that little bit nicer looking defender. Lol

Ha, ha! Hey Jeroen! I thought I better get that rear diff locker so I can keep up with you Or incase you are in Hawaii when I get stuck

Yeah, I will just repair what's needed and upgrade that half shafts. I still need to know for sure that it is a 3.5 ratio though. I will need that info to order the right parts.... It sounds like it has to be a 3.5 ratio....

I think upgraded flanges will not fit the booster alloys. Got to check that too.
