its a weird one all right.

The cdl is disengaging when you deselect it? (windup when you are not expecting it?) Same tyres of similar wear all round?

Maybe just a couple of dud diffs?

Hope you get a solution!

Stanard rover diffs are crap . If you have big tyres and or a heavy right foot time to upgrade to either lockers or something as good

An excuse for lockers? Maybe this is a good thing. ...

Was it the planetary gear pinthat let go?

Looked under car. Both front and rear diffs turning but no drive. Got rear diff replaced. Went camping 700 km with rear wheel drive only. Came home went out Bush to scrape of mud. As I turned in mud on flat ground I heard the clunk again. Another diff . Please see pic. Need help urgent.

What is that wet looking thing at the bottom of the case ?

According to your description your Landy diffs arn't going to blow that easy. There has to be a logical reason.

Tyres?? Same size all round? Centre diff is is disengaging? Are you using the correct oil? Is there a bad oil leak at the axles?

The diff you initially put in, was it new? 2nd hand? What blew in the diffs??

I'm not up to speed on the TD5 traction control OK but is it possible that when you "turned in mud on the flat" the traction control bit in on 1 wheel and caused it to blow??

You have to think logically. Were they whining before they blew? Diffs don't just blow. In fact they don't blow 99.9% of the time.

A couple of things..

1) From your first description, i.e. engaging the cdl & letting the clutch out, the car should move in front wheel drive. You say the front shaft was turning. So a CV or diff has let go in the front as well.

2) You drove 700 kms on the rear diff, then loaded it up. I'm not surprised it let go, it's taking twice the load. Driving on one diff only with CDL engaged is really emergency -get-me-home stuff only.

3) The pic is interesting, there's a hole in the casing. Has it had a whack in that region? Is the casing touching the CW&P to wear that hole? Not unknown, that's why we fit diff guards.

Besides what we do know, have you checked your housing is true?

If its bent, you'll be loading diffs up all the time...
