That is odd. Could the gears in the rear diff be completely stripped? Although I agree, you'd probably hear something if that were the case.TehPriest said:Conclusion? Well I am not sure. If it were the diff I would hear it surely. If it was a Series Land Rover I would guess that it had snapped a half shaft but even then it should make some noise.
I've had several rangies with that problem.
It's simple: the visco is completely blocked so it is like driving with difflock on always. Something has to break and thet is normally the front or rear diff.
You can drive normally, there is no special sound but you have only 2-wheel drive. Repair is siple but expensive: change visco and one diff/axle.
That visco is rubish on older cars, better have a manual difflock like defenders and older rangies.
Good luck, Cai (Liège)
So it could be that it has stripped the splines or seized and stripped them or seized and taken out the diff (no noise so unlikely)I had this exact problem last month - turned out to be the r/n/s half-shaft which had stripped it's inner splines. Cost of repair - £12.50! (ebay) & 90 mins struggling in the cold. Are you sure your rear half-shafts are okay?. Also, you can check your viscous coupling very easily - put the transfer box in low neutral, hand-brake on & jack up a front wheel. You should just be able to turn that wheel if the v/c is okay. Also, if it's gone the front wheels will scrub like buggery going forwards on full lock (if you restore the 4wd first...). V/c's only ever seize solid, it seems - they never go to full slip. Cheers, Mark.
Try this before driving further!classicjack said:Remove front driveshaft and use big breaker with socket an flange nut, 32mm I think, turn clockwise and coupler will turn with much resistance. I cant remember the specifics but its something like at 40lb ft torque it will turn 1/4 turn in 30 sec. Test is done with wheels on ground. If coupler is seized it will not turn at all. If you want to drive you can leave driveshaft off. I'm sure if the ex drove for some time wilh bad coupler it damaged cv joints.
