Rear gearbox oil seal was created by Danparry
I’ve got a 2006 vvt m13a jimny and I’ve noticed abit of oil that has been sprayed around in the same area as the rear gearbox oil seal,
there’s no oil leaking on the ground just kinda moist with oil around the area,
ive had my gearbox rebuilt 1year ago there’s no oil anywhere else.

my question is,
is it a big deal at this point like does it need fixing ASAP?
and if so is it’s best for a mechanic to do it or is it a easy job to do at home?

also if so is there a workshop manual to show me how to change it?

Hi it's not a hard job to do if you've changed oil seal before
If you're not changing the oil at the same time.You will need to put car ramps under rear wheels
this stops any oil escaping when you pull the propshaft out.
You only need to remove prop from gearbox to the transferbox.
There is not a lot of room to work in,I used a good fit socket with 6" extension bar and a lump hammer to tap new one into place 
Genuine seal from bigjimny shop at a reasonable price

It's quite likely it could be the propshaft that you need to look at. You can seal the hole in the propshaft or buy a new corrected one but they're expensive. Have a look back through the site and you will get plenty more information.

I wasn't planning on changing gear oil as well but is it easier to do so to complete the job??
I've never changed the oil seal before.
I've just ordered a new seal for it.

Ohh OK
Has there been issues with the propshafts.
How would I tell if it's the propshaft that's the issue??
And if so what sort of glue or sealant is best to seal the props haft hole with?

Ahh I see
I'll check that as well,
What's the best epoxy to use any recommendations?
I've got some loctite si 5920 in the shed would that be of use at all??

Also the epoxy where exactly does it need to go?
Does it go around the yolk that fits into the seal?

I'm good with pictures if thats easier to describe it haha

Hi, there is no "glue"

There is a metal cap that is a "push" fit inside the yoke. This leaks oil.

People simple coat it in oil resistant epoxy. You can just about do this without removing the prop but its easy to pop it out and properly coat it.

Here are some pictures of a poorly done (but effective) repair - not done by me!

Yep thats what mine looks like,
Definitely the issue then,

What other tools would I need to fix it?
Just the bearing oil seal and some epoxy putty to seal it up as well?

Do I need a bearing puller ? Or not worth it
Also should I purchase some more gear oil ?
I have enough to top up but do I need to drain the gearbox to do the seal etc?

Sorry for all the questions I just don't want to start the job then. Not have all the stuff to finish lol.

As someone said. Make sure the rear of the car is higher than the front so the oil stays in the gearbox when you pull out the prop.

All you need is some spanners to undo the prop bolts. I would undo the rear as well so you can move the transfer box back a little bit to help
