New Ashcroft Rover Differential? can anyone confirm

Thanks Keith! Hope all is well over there?

I suspect that we would probably travel the Sals OR a beefed up D1 housing route and Locker/axles etc as the Force 9 whereas it is an awesome bit of kit is a bit outside the budget of a strong reliable tourer.

This particular application isn't about heavy loading either, so conceivably a D1 rear housing should suffice, but have to check permissable axle weights I guess first to remain 'legal'.

We may just have to settle for a Sals it is just getting hard to find a good used one, ABS compatible.

... and here is me thinking that I need to check the ARB locker applications guide to see what has a Dana44 and then to work out what has a drop in type diff..... hmmm, where is my old Frontera V6!

so what would be ideal, is to use the P38 type housing and supply a drop in 3rd. Keeping 3.54 gearing and 24 spline axles, with the option of upgrading. Of coarse a locker option to. So what 3rds will fit and are common?

In that case, if a Rover pattern 3rd drops into the P38 housing, the Jack Mc hypoid/Lolux centre as Bill suggested in the other thread.
IIRC he mentioned Jeff had 3.54 CWP's made and they were pretty nice.

Don't know about that but there ashcroft lockers are selling so well they sold out.:)

I don't think they do Rick, otherwise Ashcroft could just supply the Rover Diff with their upgraded ring and pinion.

Rover diff will drop in to a P38 housing, but a P38 diff wont drop into a Rover housing, so based on that the Toy should be a comparable conversion to a P38 housing as it is to a Rover housing - although I'm not sure how the P38 housing CW cut out affects things.

I think Rick is talking about the physical size. The Rover type R+P is different design to the P38type, so you cant just switch R+P.

When I say drop in, I mean fit. The only diff center to bolt straight in is going to be the original P38 type. This is about what removable 3rd centers will physicaly fit in the housing.

The Toyota 8 or so inch hypoid has been mentioned. Now I know most will say they are a huge improvement over the Rover, but I have read a bit over the last few years and the mubblings arnt quite agreeing with that anymore. For my way of thinking, if you are going to the trouble of doing a custom job in the P38 type housing, make it as good as can be within reason.

So if a larger Toyota or Nissan center fits, then thats a start. What ever I would choose would have to be common and have a 3.54 or very close ratio....

Im guessing a diffferent 3rd would require either the studs being removed and weled up, or a spacer ring inbetween. The rear cover may have to be cut off and replaced if the ring gear is going to fowel....not such a bad thing as the cover is probably only 3mm thick....

Serg, the problems have been with the reverse cut/high pinion TLC fronts, apparently the standard low pinion in the rear (or front) is plenty strong enough and much stronger than the Rover diff.
Bill for one reckoned they are a good thing and Jack Mc make a casting for it to be a bolt into a Rover housing.

With a 3.54:1 CWP the pinion head is 21mm larger than a Rover pinion. (and I'm trying to find the thread where this was discussed :()

[edit]
Found it !
Actually it was Bill and Matt (Rovercare) who both said they are a good thing http://www.aulro.com/afvb/90-110-130...r-diffs-3.html

Yes, in comparison to the rover stuff

This has got me thinking, when I build the p38 I'm thinking of diff conversions and what to do, I have a jacmac hypoid 3.54 centre hidden away, oh well it's a while away
