Brasco Posted February 20, 2011 Share Posted February 20, 2011 Hi there.. so i got this 1989 range rover with 4 speed auto box. I removed the front prop shaft for a service and tried to drive the Range but there is no drive at all. I switched to low gear, but nothing happened. So i would like to know if it's normal or if there is something busted in the transfer case with regards to the rear drive. thanks Quote Link to comment Share on other sites More sharing options...
RoaryV8 Posted February 20, 2011 Share Posted February 20, 2011 It should drive with no problem, Gather you have a Borg Warner auto locking Transfer box in it? if you have then sounds like its not locking itself, which is what mine isn't doing, so replacing it soon. If you have a manual locking T/Box then make sure the centre diff is locked. Quote Link to comment Share on other sites More sharing options...
willfromsussex Posted February 20, 2011 Share Posted February 20, 2011 If it has a viscous centre diff, this could be worn out so is working like an open diff, and only turning the easiest side (one with no prop shaft) . Does the viscous one have an auto lock mechanism ? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 20, 2011 Share Posted February 20, 2011 It should lock up, I have driven my Borg Warner box breifly with no front prop on and had no problem getting drive -only for a couple of hundreds meters of course They normally failed locked, but can fail open, which may have happened here. The other option is that if the rear prop *IS* turning, you have a snapped halfshaft/blown diff in the rear axle -engage drive and get a mate to check underneath to see if the prop is spinning.

zim Posted February 20, 2011 Share Posted February 20, 2011 On the High - Low lever, can you push it across to engage difflock ? i.e. have you got an LT230 and not a viscous coupling. I'm not sure what models they came on ? G Quote Link to comment Share on other sites More sharing options...
Brasco Posted February 20, 2011 Author Share Posted February 20, 2011 update...the high/low is operated manually.. the only thing i did not try is activate the difflock. i just switch from high to low...does that make a difference?? this afternoon i removed the front prop on our other Disco 200. its a manual...but same thing...no drive...but i did not switch to low gear... so that means both landies have busted transfer boxes ??? thanks for the all the replies.

bishbosh Posted February 20, 2011 Share Posted February 20, 2011 With no front prop you will have no drive unless you either: a) Have a Borg Warner transfer case (unlikely on the Disco, or b) you lock the centre differential by pushing the hi-lo lever across to the left. My money is on both vehicles having an LT230 transfer case so just lock the centre diff and away you (should!) go! Quote Link to comment Share on other sites More sharing options...
RoaryV8 Posted February 20, 2011 Share Posted February 20, 2011 Yeah from what has just been said, you need to manually activate the diff-lock. LT230.. So push the Hi-low lever across to lock the centre diff and you will be able to drive in front wheel drive. Quote Link to comment Share on other sites More sharing options...
Range Rover Blues Posted February 26, 2011 Share Posted February 26, 2011 B-W came in roughly in line with the concealed hinges for the USA market, IIRC. Anyhoo, as said you need to establish if the fornt prop falnge is turning or the rear prop is turning then you can work out whether the rear drivetrain is bust or the centre diff, assuming of course you didn't merely forget to engage a LT230 diff lock.
