Drivetrain problem


Recommended Posts

Well the 110 (1996 300Tdi) has let me down for the first time today after 42K miles of ownership (169K total).

Like most vehicles of this age there was some slack in the drivetrain but I'm a fairly gentle driver and usually manage to drive around the problem. Coming up to a few road junctions on the way home last night there would be a thud from somewhere, though it wasn't immediately after using the throttle or brake, infact I don't think I was touching either when it occurred. I made a mental note to have a look at it when it stopped raining, or the weekend, whichever was sooner..

It appeared fine this morning until I came to the first main road junction after about half a mile. Half way across turning right

(typically) I lost drive and thought something had locked up at the back. It initially tried to move but didn't get very far. I put the centre diff lock in and was able to drive it back home, then borrowed the wifes car to come to work.

I'm guessing it's more likely to be a problem at one of the axles than the transfer box, hopefully a rear driveshaft or drive member in terms of both cost and time.

Should I just pull the rear halfshafts and have a look - OR - take the difflock off and ask swmbo to look at the driveshafts (from a safe vantage point) to try and identify which one is turning and hopefully point to the offending axle? If this is likely to lead to more expensive damage then I would give it a miss.

do that very easy takes 10 sec and the end that is spinning freely is the end that is broken or if neither prop is spinning then it is in the transfer box but that is fairly unlikely

if it is the rear it may well be the splines between the halfshaft and drive member on rear axle as spline failure is a common problem on vehicles of that age, not expensive or difficult to fix, and you will notice a lot less backlash in the transmission than before once you have fixed it (if one has lost its splines, change both side as the other one won't be far behind). To confirm, if the rear prop is spinning, pop off the black plastic cap on each side while somebody is driving it, you will see the stripped shaft spinning in the middle of the flange. It could be halfshaft breakage which will require shafts pulled out to confirm but this is much less likely if it went on the road.

otherwise, diff centres are known to go in the front, and the next stop is probably the CV

Spot on. Rear prop turning - LH drive shaft was rotating in the drive member. When I took the plastic cap off to identify which side it was lots of metalic pieces and dust fell out :blush: .

I'll replace the shafts and drive members on both sides at the rear (land-rover-parts-shop.com looks to be the cheapest) and will try mmgemini's idea of putting some EP90 in the cap before refitting to try and lubricate the splines.

Is it likely to have contaminated the inside of the axle casing or will I get away with changing the oil just in case?

Thanks again for the advice.

The axle oil should be fine it is possible that the wheel bearings might have some muck in but TBH I think most of it stays inside the drive member. Have a look when you take the drive member off and make a judgement as to whether you need to clean out and re grease the wheel bearing then, would be my advice.

Right again - most of the mess was contained. A little bit fell into the hub when removing the drive member but that was easy enough to remove.

I've decided to change all of the drive members, and both rear halfshafts as the one from the stripped drive member was very worn. I called into my local LR dealer and they wanted £81.27 + vat for a single drive member!! When I pointed out how much I'd spent over the years they offered me 10% discount - I declined their offer and somehow managed not to laugh. A local specialist sold me 4 drive members plus the 2 rear halfshafts for £81.12 including vat.

The new halfshafts won't be in until tomorrow but I changed the stripped drive member so I was at least mobile again. What a transformation - all of the clunks and bangs have now gone :)
