Transfer/Gearbox leak
I apear to have a leak between the gearbox and transfer box. Vehicle is under extended warranty until September, I will try and get it done under that.

If not, is it an easy job? Checked the manual, a bit of work involved, propshafts, exhaust, hand brake etc. I have a ramp at my disposal.

I couldn't see a gasket or seal mentioned in the manual, could have missed it though.

All advice, ideas welcome.

Cheers

I would think it to be oil seal output shaft from gearbox or oil seal input shaft on transfer box. Neither is an easy job as they require transfer box removal. You should be able to tell which box it is by determining what oil it is and box oil levels may help, depending on size of leak. But check your breathers for the boxes are clear before you undertake an work.

I've just swapped my box over and replaced the drive shaft seals between the gearbox and the transfer box, it's a 5 minute job once everything is apart. Just pull the old one out with a screwdriver, tap the new one into place and bolt the box's back together. When I say 5 minutes, I mean after taking the prop shafts off, handbrake, speedo cables, transfer box off....

Flippin heavy job best done over a pit or on a lift, not something I'd like to do alone.

Thanks for the responses.

I'll check the breather hoses tomorrow.

Like most thinks the seal replacement is easy, it's just getting to them.

Cheers

Ok about to get on with changing the seals this weekend.

The transfer box looks straight forward.

But is the output shaft seal on the MT82 gearbox easy to change without the special tools listed in the manual?

Thanks.

I would check with a dealer before doing this myself, since taking the gearbox out is a routine job for them and *might* cost less than you think. With the right equipment (such as the special transmission jack and adaptor) you can probably do the job in about an hour.

Even if you pay for a couple of hours labour it might be worth it to avoid the hassle, or the aftermath of dropping the transfer box on your foot.

Checked with them, they'd need it for the day minimum, I didn't ask the cost as I din't have anywhere to sit down.

The transfer seals should be easy to change, it's just the gearbox output shaft seal that could prove interesting.

So decided to do the transfer seals in place. The worst one first. The front one.
Removed the prop-shaft and thought the o/p flange seemed loose, in fact it was. The retaining nut was loose and the flange was floating.
Changed the front diff seal whilst I was at it.
Checked the rear o/p seal all dry so it looks like it was only ever leaking from the front and throwing the oil everywhere.

The seals are easy to change though In place. Easier on the ramp for sure.
