There is a bucket load of play in the transfer box and I'm contemplating fixing her with a new one but I wondered if it was a common problem that can be fixed with a part rather than a refurb'd box? Should I be looking at the mainshaft? I have heard they were a bit iffy in the early 300tdi's

I'm wondering if I should just do this.. My gearbox doesn't feel too great either tho. How much was the gear?
Well the first one i bought was from bearmach 45 pounds cant remember if that was plus vat though.
This was wrong as i ordered the wrong part! FRC5089
Went to fit it late at night as im also fitting a pto, so thought do the whole lot and ignore it until it clunks again.
So went to my local place island 4x4 and they had the correct early narrow gear under 30 pounds but was by britpart! but i needed it to get the job done so i bought it and fitted it runs quiet and as i said above the clunk has totally gone, obviously not for ever but i reckon 10k, and for 30 pounds who cares?
I have done this on two disco transfer boxes before , both did over 50k and the clunk never came back, these were fitted with the later cross drilled gears, mine isnt cross drilled as its an early range rover tfer box.
Early gear FRC5428 non cross drilled

Common for the main shaft splines on the gearbox to wear and the transfer gear that slides over the splined shaft to wear on LT77 and R380 boxes.
Changing just the gear will take 50% of the wear out but the worn splines on the output shaft will wear the new gear at a fast rate .
Also the worn shaft is still likely to shear ,leaving you with no drive.
Easy to check gear and shaft wear by removing the round cover on the transfer box ,which is also where you access the gear to replace it.
Ebay is where I bought my replacement gear box and transfer box for a snip of a price, before I parted with my money I checked the shaft and gear which were in excellent condition.

Yes the remainder of the worn splines would strip not the shaft snapping, thats what I ment.
Your right about just replacing the gear being a bodge.
For me I pull a trailer with a couple of tons on it and I dont want to chance it.
My last gearbox had less than a quarter of its splines remaining on output shaft.

Got the same problem with mine, I only do about 2000 miles per year in mine so might give this a go.
Anyone know of a photo guide on this?
