No drive

Defender 90 owner Whilst pulling away from a roundabout all of a sudden i heard a bang and there was no drive in any of the gears, does anyone know of any possible causes for this?Thanks in advance Ian.

any drive in difflock? If you have drive in difflock but not with the diff open most likely halfshaft or sheared cv joint

If no drie in difflock, another option is clutch disintegrated, mine went with one helluva bang, but stunk of clutch....

More serious options then become gearbox or transfer box prolems

Probably, I'm afraid. I'm with Merlin on the splined shaft theory.

On or around Sun, 04 Jul 2004 20:36:25 GMT, "Ian Hamilton" enlightened us thusly:

sounds a lot like the gearbox output shaft splines have given up the ghost.

your potions include hunting a second-hand box (but it's bit of a lottery if it's a good 'un, unless you know the donor vehicle)

you can instead rebuild your box or have it rebuilt, or get the pros to rebuild etc.

as someone else said, make sure you get the "cross-drilled transfer gear", since otherwise the wear starts again.

It could be summat else, of course, but this is far the most likely as it's the biggest known cause of death in these things.

I'd say you've broken a halfshaft. Engage the difflock and see if it will go. If so then you're going to have to get busy underneath.

Ashcrofts replaced my gearbox and clutch for about £900, including parts and labour. Make sure you get a new clutch fitted at the same time, because that will be about ready too and the gearbox has to come out to do it.
