110 Salisbury Diff HELP!!
Discussion
I was driving along at the weekend and the passenger side rear wheel locked unexpectedly and caused me to have to make an emergency stop (much to the car behind and my surprise).
On inspection the rear propshaft to diff seal was smoking and bubbling with what I assume was oil. The propshaft also had an excessive amount of play at the diff end. I've had the car for about 18 months now and have taken for granted that there was actually oil in the diffs.
Q: If the oil was low in the diff casing, would this have such an adverse effect on the wheels turning or am I looking at damaged parts in the diff itself. After a few miuntes of head scratching the wheel turned freely and got me home (some 90 miles although cautiously).
Has anyone else experienced this or simalar who might be able to assist. I'm comfortable stripping the diff down if need be, but interested in anyones views beforehand.

Hi,
If, as I suspect, you have run it with insufficient oil in the rear axle then I would expect the bearings to have failed in the differential pinion and probably elsewhere too. Not too familiar with Salisbury rear axle (aka Dana 60) but know that you will need a stretcher to expand that case in order to remove the differential itself and so obtain access to the pinion. There are quite a few websites with PDF versions of the LR workshop manuals - have a hunt and read first...

I don't know about the front one as it's only the rear that is concerning me at the moment.
I have a RR classic that I'm going to use for a Tomcat soon, but might need to use the axles from this as a temporary measure although unsure if the rear discs will cause a problem with any differences with the pipework.
The salisbury axle/diff hasn't seized completely yet and did a further 100 miles after the lock-up, so from what I know about it, it's as good as dry and needs a top up. I appreciate that the lack of fluids won't have done it any favours, but as I don't use the 110 daily so will top it up at the weekend and see how it fairs for now.
Do 24 Spline diffs have a different ratio? Other then in strength, how would this benifit the 110 over the 10 spline?

Hi,
24 spline half-shafts are inherently stronger than the 10-spline type. Similarly a 4-pinion differential has twice as many spider gears than a 2-pinion and a stronger carrier too. You might get away with using a disc-braked 10-spline rear axle for light duty but if towing you'd need to be very gentle with the clutch. Having said that I've run 10-spline drivetrain components in my Bowler 100 for ten years now and only broke one differential - and that was when snatching a heavy stuck Range Rover. Post-mortem of the differential revealed a flaw in the spider gear's cross shaft.
I'd suggest that you remove the rear cover from the Salisbury and have a look to see what is damaged - a cheap way to decide what path to take next...
