Help our TD4's just siezed up and won't move

[Gee-dub-ya]

Our 2003 td4 has just ground to a halt, there's been no noises rumblings or warning signs. This morning with the wife driving it started holding back like the handbrake was coming on, then it spluttered and kicked the rear end out sideways so she parked it up.She said it made a clunk like something fell into something else. It will tick over fine but is very very reluctant to move, i managed to get it to move a bit but there's a very strong smell of oil and rubbing noise, and when i dipped the clutch it virtually stopped on the spot, so i've parked it up.

The clutch seems to still be working.

Any ideas apart from it being expensive?

Ird sounds shot or the rear diff, or both, probably because of a faulty viscous coupling

Not liking the sound of all that, whats the likely wallet damage for that little lot?
Just been out for another nose the clutch is defo ok, gearbox feels ok, but it absolutely stinks of oil.

Are there any leaks underneath? Can you jack it up and turn the wheels, listen for noises around gear box and rear diff and any grinding etc. does it move out of gear? Ie can you push it?
Your talking about a grand for that lot, but lets not go there yet.

Can't see any obvious leaks,might be a small leak from the rear of the engine but the roads wet and it's hard to tell can't see anything dripping. it's not really in a position for me to be able to jack it up. Tried pushing it, will move slightly with a clicking noise that seems to be coming from the rear. It's like the handbrake is partially on

Have you had any new tyres put on recently?

 

[AKeeNShoT]

Rear diff.

 

[AKeeNShoT]

Take the prop off if you can, to prevent further, if any, damage to the ird, that's the expensive piece.

Only part worns on the front and they were lower tread than the rears

just spoke to a specialist and he reckons it sounds like the ird, but he's booked up till the 10th.

Good luck with that, keep us up to date .

Ok .....same make and model of tyre?
It does sound like the rear diff as it is common for it to get wound up with a failed vcu which would cause the oil to boil giving you the smell of oil.
As said remove the prop to prevent further damage.

 

[Gee-dub-ya]

If the ird's shot is it too late to swap it to 2wd?

or if can you 2wd with a dead rear diff?

Is the prop removal easy? wouldn't know where to start

Tyres were the same size, but different makes

 

[mjrimmer]

Tyres can be the same size but have a different rolling circumference between brands.

Prop removal is a 25 minute job if you're spanner savvy, 14 bolts.
Though it sounds as though the damage is done already I'm afraid.
Without knowing for sure, removing the prop, and jacking the back end up and trying to turn the wheel would seal the deal.

If the diff is shagged then you can remove the prop and remove the rear drive shafts...just leaving the wheel hub end of the drive shafts still in place.

Just watched a youtube clip, i reckon i could sort that but i have no way of all 4 wheels off the deck at once.

Anywhere recommended for parts?
