can anyone help

hi i came to an island last night in my defender and as i put the clutch in to change down a gear there was nothing there there was abit of clutch smoke and a little grinding noise then no drive its a 300 tdi someone said i know that the arm that shoves the thrush bearing sometimes jams or breaks as anyone experinced the same cheers

what clutch smoke?
can you select gears at all, or not?

if the release fork had failed, i would expect a solid pedal.

ive just been out and tried it i can get all gears just no drive i put it in diff lock high and low and i get drive but dont get drive in normal high low range

sounds like a half shaft or something. Jack up each wheel and turn it, until you find the one that doesn't make that axles prop shaft turn. Then, you've found the fault.

LOGIC!!

If you have DRIVE when the centre diff is LOCKED, then we can be SURE that both half shafts and the differential in at least ONE axle MUST be intact.

Because you have no drive when the centre diff is FREE, ONE of the two prop-shafts MUST be spinning when you try to drive off. This can happen if ONE (or both) of the wheels on that axle are not driving.

Apply the handbrake.
Place transfer box in HI and Diff NOT locked.
Start engine.
Get an assistant to watch the front propshaft from a safe position at the side - where he won't be run over if the car moves.
Engage first gear and ease up the clutch and ask him to shout if the front propshaft starts turning.

If it does, almost certainly one of the front halfshafts or a UJ is broken, or the front diff is jiggered, which is less than likely.

If the front propshaft doesn't turn, the REAR propshaft will be turning, and one of the REAR halfshafts is probably sheared - broken, or the rear diff is jiggered, which is less than likely.

Diagnosis is 90% logic and 10% luck.

I call the wobbly bit on the end of my propshaft "Landrover"

So, the front propshaft was spinning but the car was not driving?

If that is so, BIG problem at the front somewhere.
Basically something is broken. All you have to do is find oiut which bit and fix it!

Or are you saying you already know what's bust?
