Does anyone know how difficult it is to change the output seal on a VVT gearbox? I am being told that the tcase needs to be removed or the engine and box pulled forward. Once you get access to it is it easy to hookout?

cant see it being much different to the one i did on the rear of my gearbox. mine is the g13bb engine though. still remains that the prop has to be removed betwen the gbox and tbox at the gearbox end. no drama there though. the seal if it is the same is a bugger to "pick" out. quite easy to get to though. got my seal from bigjimny shop

standard jimny - for now

It's simple, all you need to do is remove the prop shaft then pry the old seal out, is it definitely the seal leaking and not the prop uj, Jenny's had a technical bulletin about the prop leaking the gearbox oil out. Their solution was for the customer to buy a new prop. I just slapped a load of silicone instant gasket stuff on to the prop to stop the oil leaking out and it's been fine ever since as after if done the gearbox oil seal it was still leaking and cost me a new gearbox

Ditto to the last post. It's a fiddly job as the gearchange linkage/mounts are different to earlier cars and the seal is a bit tucked up inside the mounting brackets.
The exhaust also has to be dropped from the joint with the springs to get the prop out.
There was a faulty batch of props and the oil leaks down the splines through the sealing adhesive inside the yoke of the UJ.
As said Suzukis answer is a replacement prop(different part number) and a seal .
I had my seal replaced and it didn't cure it but mine was out of warranty so I had to pay for a prop although the garage didn't charge labour.
It's the same seal as earlier boxes so there is no reason to suspect the seal as it has proved itself on earlier cars but worth trying anyway as it's only about £10.
Just keep an eye on the oil as it only holds 1.3ltrs so even a small leak can cause gearbox problems.
Overfilling is also a problem so let it all drip out until it stops dripping out of the level plug(car level of course)

I started off high and worked my way down ever since :-)

Just to revive an old topic rather than start a new one...

Anyone have any tips for getting the rear output seal out?

I've tried levering it, tried getting a self-tapping screw in the pulling with pliers, all to no avail. Am worried I've nicked the inner shaft, but that's a problem for another day, just want to get the damn thing out!

I bought this or a similar kit. was easy when the box was out anyways, but it should be doable with the box in the car. Remove axle and exhaust and possibly gearbox rear bracket.

You can get oil seal removal tools. Machine Mart do them.

An old trick is to screw a self rapper into the side of it and use that to pull it out.
