Thread: Fitting 300tdi into v8 disco1, and switching to 5 speed and toyota axles

Why would you go to the trouble of fitting Toyota axles (I presume you mean the whole axle (diff) housing), they are crap. Instead stick with the Land Rover and fit ARB diff centres and Maxi-Drive axles (shafts) and end drive plates, as strong as you will ever need, a straight edge across the oil filler cap on the top of the rocker (tappet) cover leaves about 1" of clearance on the guards opposite (fenders/wings, whatever you call them over there) good luck, Regards Frank.

thanks for the info Frank, ive been fooling with the height and that is where I landed as well.

perhaps i should have been more specific. Im using toyota fj80 front, LX450 full floater rear. hardly junk by anyones standards.

It is very strange to me that neither the LT230 to gear box, or gearbox to engine has any alignment pins. it appears the gearbox bellhousing is threaded to accept the pins, but theres no pins.

the dowels / pins must be missing,

You are fitting a 300TDi, not a real powerful motor the likelihood of breaking ARB diffs and Maxi-Drive axles (and you get Lockers to boot) are near impossible and LR diffs are full floaters.
I have no Idea what an FJ80 or LX450 are but the only Toyota I ever owned (BJ40) from new when only a month or 2 old lost a pinion drive nut on the rear diff and the pinion shaft slipped down under the crown wheel and totally destroyed the whole rear end. I also had the unpleasant trait that Toyota diffs have of that they don't like going backwards, broke both front and rear diffs (at different times) under warranty while reversing out of a bog, 3 Toyota diffs in the warranty period.
LR diffs have better suspension setup than Toyota and the front swivel housings can be changed out if damaged by undoing 6 (or so) bolts.
I have had no problems with my Land Rover ARB diffs and maxi axles for over 10 years now, I have had these same diffs and axles in a 3.5 V8 Disco, a warmed up 4.0 V8 Disco and now in my 300TDi Disco, so they get around and never a problem, Regards Frank.

D1/ RRC diffs arent full floaters, as far as i know only the salisbury diffs are. 80 series diffs are a good swap as they give you 4.11 gearing and the rear diff is the right off set for a rover, will also help with the tdi and big tyres.

All rover axles bar S1 are fully floating.

If you'll break rover diff's with the 300 then you'll do the same to Toyo stuff. Leave them there, fit lockers, ARB, Ashcroft. Lucky 8 in NY will have everything you need in stock incl the dowels for the bell housing to engine and the gearbox (,or at least can order them).

The toyo diff will be the wrong width, wrong centre offset, different stud pattern, need new suspension mountings and brakes will be worse and need adaption (metrc Togo stuff to imp rover fittings). Very few if any benefits with a large cost and outsourcing of stuff like shortening diffhousing, make/respline new axles to suit.

Yea, they are all full floating

If you can fab stuff and I'm guessing the tojo stuff is dirt cheap, fit it, don't worry about the naysayers, if its a bush mobile its all good, bigger brakes, better ratio and dollar saving

If on the other hand you were paying I'd stick with rover stuff and do the usual lockers and axles

I've seen very, very few damaged swivel housing and I'd suggest if you damage one, you have more things to worry about, the only real joy of bolt on swivels is the ability to slot the holes for castor correction, whereas the jojo stuff you have to cut the weld and rotate the ball

Isnt full floating meaning that the axles are not fixed to the hub mount like D1/RRC are ? Front stubs are floating as they are splined and have the circlip to hold them in position.

Dont mind me, i was thinking of floating V semi floating - carry on
