Hi Rangrig
You may have a problem, but I would think the chances are slim.
1 You will be controveneing the construction and use regulations which are the regulations that all vehicles are built to.
2 You will be invalidating the type approval certificate that Landrover had to obtain when they submitted that type of vehicle for the approval. Eg it was submitted with a non ABS front axle.
3 A cute MOT examiner might pick it up and query it or fail he vehicle.
All these things sum up to not being much, until it all goes tits up.
Normally a serious accident or definately a fatallity on the pubilic highway. The police will impound your vehicle and carry out an inspection of its roadworthyness and legallity. Upon finding anything suspisious they will follow it up. If it is found to be illegal then from an accident that was not your fault it can be reversed due to the fact that your vehicle should not have been there in the first place. Even if the authorities take no action the offended legal team may very well.
So I would first check and inform your insurance company of your intentions. I would also discuss it with VOSA Vehicle Operating Stanards Agency. Also your area Police force, you want the traffic division not the local bobby.
You will probably find that there is no problem at all. But when you start to play with the regulations then it's best to do your homework first. The alternative may not bear thinking about.
I hope I haven't depressed you. Sorry.

construction and use dont apply nor does type approval as land rover will only have put one car in for type approval,abs or non abs it wouldnt have mattered, as for m.o.t just because it has abs rings or sensors on we would still have to look for an ABS pump to confirm it had ABS as standard, as yours was never fitted with ABS it wouldnt matter it can NOT be failed, you will probably find the holes are there for the sensors any way but the proximity ring on the hubs will be missing i would guess that the other way round (fitting abs to a none abs car)would cause more of a problem to insurance or in case of an accident as they would not be able to confirm it worked as it should as said before if the ratios are the same then i would just fit the one you have got if at all worried take the gears and shafts out of the good one and fit to the none ABS casing
Food for though indeed, the trouble is the diff in mine (front) is leaking and want to exchange the whole thing. As I said, I swapped the rear from the donor car (same year, 200tdi, but with r380 box) after 3000miles the transfere chain rings like a bell. So i want to swap the front axle to pair with the rear and put the r380 in. My lt77 had viscous diff lock, the r380 is selectable. Will this be Ok?

Sounds like the 200 Tdi back axle has a different dif ratio than the RR front. You should have changed both axles at the same time. If you change everything as stated it should do the trick.

They are all 3,54/1 ratio.What a fuss ! Just change the top swivel pins for non ABS and nobody will ever know.

Standard diff for 200Tdi is 3.45/1. 3.54/1 is an alternative but not a standard fit. You must have the same ratio front and rear. From what he says about transfer chain obviously this guy does not.

Really ? I think even Land Rover would argue that.Borg warner transfer boxes dont need an excuse to pack up,his diff ratios are BOTH 3.54/1 and are not the cause of the TB failure.

He says he has fitted the rear axle from a 200 Tdi the diff ratio of a 200 Tdi is 3.45/1. If the diff ratio of the front axle is 3.54/1 that would cause the transfer box problem.

If you want to argue at least know your product - they are all 3.54/1, read a LR W/S manual or look at Ashcroft Transmissions if you need more info.

No need to read anything. Discovery 200 Tdi have two diff ratios 3.45/1 and an option of 3.54/1. It depends on your model, chassis number which one is fitted. If the 200 Tdi this guy has is fitted with 3.45/1 axles they they will not match the RR 3.54/1 axles. He has changed the rear axle only this could give the problems he has with the transfer box. I do know my product. I had a 200 fitted with 3.45/1 axles i also have a 300 fitted with 3.54/1 axles you cannot mix the two. OE: Differential P/N FTC 2750 3.45:1
ratio. Alternative fitment OE: P/N FTC 2750R 3.54:1 ratio.
This is useful stuff. I could add to it by confirming the numbers stamped on the new rear axle, however, I scrapped the old one so no comparison. Surely the transfere would have packed up sooner? I drove to cornwall from the lakes and back (and all over cornwall) with no probs at all. As I say, 30000 miles after the swap came the issue. If i haven't done the rear diff in, i hope swapping the lt77 with viscous 230 transf. for the r380 with selector 4wd should solve the issue. Does this spund ok?

Not really interesting - they are ALL 3.54/1.The only difference btween early and late is 10 or 24 spline halfshafts.

mike,
In the interest of sorting this diff ratio out. What year and model RR have you got?

I've never heard of different ratios on Discovery diffs, I suspect there is a miss print somewhere.
Until the independent suspension vehicles came out there were basically 2 diff ratios on Land Rovers (with the exception of very early 80" and the 101)
4.7:1 fitted to leaf sprung vehicles and 3.54:1 fitted to coil spring vehicles. The exception was the Stage 1 V8 that had leaf springs and a 3.54 diff.
There were some other ratios that were fitted to Rover saloons that will fit.
Wammers, what makes you think your 200 has 3.45 axles?
I would expect an NRC2750 to be a new diff, an NRC2750R to be a recon, that is usually the meaning of an R on the end of an LR part no.
