Subject says it, really.

In 4wd (high ratio or low ratio) the rear wheels turn slightly faster than the front wheels.

This, obviously, is a problem.

Any ideas on particular things I could try lubricating or hitting with a hammer? :)

Everything's fine in 2wd high ratio, with the free-wheeling hubs locked or unlocked.

Have already checked the Red Lever and the Yellow Lever and they seem fine. Not sure where to start with the transfer box.

Thanks!

PS it's a 1978 Series III with land rover 3.5l v8 and land rover diffs.
 
jack one side of car up - mark wheel and diff-prop flange with chalk - rotate wheel one complete turn and count how many turns of flange - shd be summat like 4.1 to 1 or 3.9 to 1 ratio. be as accurate as yu can and then do same fur other axle.

hand brake needs to be off and red lever in neutral (between high and low ratio.)
 
Have you made sure all 4 tyres are the same sizes and that they all have a similar amount of thread on them.

You can jack the vehicle up mark a tyre at the lowest point and turn the propshaft while counting the number of turns required to rotate the wheel exactly 1 full turn. then repeat for opposite end of the car.

bar steward he beat me to it.
 
i have the same problem with my lightweight, the previous owner thinks he had put in the wrong diff at the rear! was lots of fun trying to drive in 4wd through a muddy field, its impossible to keep in a straight line! :D

.....i did only buy it for the engine like. i've since found that the front brakes were binding on and locking the front wheels but im not sure if this is the only problem or the diff is also the wrong un. if you drove in 4wd on a hard road the front wheels would lock then skip round really fast, looked scary! :eek: was ok in 2wd apart from the smell of rubbing brakes.......

furry boots are you located? i'd swap you a diff if you like!

If only ONE wheel is off the ground the diff flange will turn TWICE as much because the other wheel is locked so the diff will double the speed of the drive flange.
