Finally got round to doing the offside rear output shaft seal today, everything came undone, had to undo top and bottom wishbone joints and pull hub and driveshaft out on the handbrake cable. Rest was pretty straight forward.



Can clean the oil off the driveway now.

Can’t catch a break spots of oil on the drive and thought it might be the cam cover again but on investigation it’s the front offside output shaft seal, same part as the rear and replacement seems similar to the rear diff. Job for when I’m off next.

Well done Steve. It never rains but it pours, eh?!

Have you checked your diff breather to make sure it's not blocked?

I'm not sure if you know this, but the original breathers fitted to these were a problem. There was a small foam filter in the end of the breather tube. Over time, the heat from the engine melts the foam and effectively seals the top! When the diff oil then warms up, the pressure builds and the oil is forced past the seals.

Mine was leaking because of this very issue. Not from the shaft seals, but between the two halves of the clamshell.

It's easy to test. Just try and blow through the filter. If you can't, chop the filter off and replace it with the LR replacement part.

Here is the old (left) vs new (right) part from when I did mine...

Sorry, I didn't read your post properly - notice it's the rear you have an issue with!  Kev

Thanks Kev, can’t believe I forgot about that! I’ll check it tomorrow. It is the front diff that started leaking, I’ve sorted the rear with a new seal.

No problem. If it is blocked, the part number for the new breather filter is LR019450. It costs about £15 from memory. When you fit the new one, cut the pipe at an angle. This will prevent the right angle of the new filter sealing the top of the pipe. Kev

Thanks for that Kev, I’ve just been to have a quick look and checked the photos on the internet and can’t find it, I’ll have a better look tomorrow.

It should be just by your coolant bottle. If you try and blow down it and you feel the air compressing, it's clear. If not, chop it off and replace

Cheers Kev, well it’s raining here this morning so I’ll try and have a look later if it stops? If it’s not been modified I’ll cut the filter off and see if the leak stops, I’ve got the new seal on order anyway. Steve

Well I found it hiding behind the AC pipes but couldn’t get any slack on it, all the AC and cooler pipes were fitted on top of it.
In the end I had to remove the grill the remove one of the plastic clips holding this baffle panel



Then managed get some slack to pull it out towards the front of the car.




The cap still twisted on it but when I removed it the filter inside was solid and you couldn’t blow through it

I’ve put some rubber tube on it for now to bring the outlet up higher till I get the new filter Steve

well done.

Fingers crossed that will stop the leak (and your headache!)

It's probably worth draining and refilling the diff.

When I did mine, I found that I had lost quite a bit of oil and what was left was bloody horrible. Kev

I had changed the oil in both diffs and transfer box recently but I’ll drain and refill the front again. Steve

So far so good, front diff not leaking anymore. Result I didn’t think just fixing the breather would stop the leak. Steve

It is Kev to be honest she’s running a dream and fairly fault free at the moment, long may it continue  Steve
