Weaping oil left side rear differential.

[craka]

The left side of rear diff there is a slight weeping of oil.

Is this what is referred to a companion shaft ?
(note this is a Gen4 NS pajero not the Gen3 which I've read about having companion shaft issues)

I'm assuming there is a seal that mates between. How hard is it to replace and what do I need in way of parts etc?

Workshop manual just shows Axle seal mate.

When apart just check shaft where seal runs for groove or wear.

Look in Differential carrier assembly section of manual its number 33.

Hey bud change 1 on mine a year or so ago. Its a diff oil seal, part number for mine was MR350883.

Simplified details to change below.

Drain diff of oil, undo lower arm from hub, undo shock from hub, undo large hub nut, manipulate hub so driveshaft comes out of it. Pull drive shaft out of diff.

When putting new seal in it needs to put in straight as to avoid pinching it. The new seal is rubber coated in effect so as you try put it in, it can grab on the metal diff. I used a very large socket as a drift that was nearly the same diameter as the seal. You have to give the drift a few taps with hammer very careful to seat the seal properly.

When putting the shaft back in, again carefull putting the toothed end through the new seal to avoid damage as there is an inner rubber flange on the seal that goes around the shaft. Then in short reinstall everything, not forgetting diff oil.

There may be a few others little things I forgot to mention but that is the basic principle.

Thanks guys,

Do you know if that is the same seal used on the diff with factory diff lock?
What's required once the shaft is out to pull the old seal out?

Also through the manual it mentions a slide hammer and adapter is that required?

[aussieintas]

Best way to work out if its same seal with or without diff locker is have a look at Partsouq.com, put your VIN in to get correct parts for you Paj.......I doubt it would be a different part number but better to be safe than sorry.

To get the seal out i used a thin small crow bar to carefully, very carefully lever the old seal out, perhaps a large screwdriver may do the job. Just have to be careful not scratch the inner metal seat where the seal sits.

To get the driveshaft out I didn't use slide hammer and puller. Used the same crow bar and again carefully levered out the shaft using the same spot where the puller sits on it. Perhaps a tyre lever or similar item should work.

Yes sorry, I i discovered that last night. Appears to be the same part used.

Thanks the info. I'll order a seal and give it a go.

Well I've just started doing this now, I'm yet to pull the shaft out but, the one thing I didn't think about is the circlip number 9 on the diagram. Is that reusable or does it need replacing once I pull the shaft out?

[Two Emms]

It's marked as "non-reusable" in that diagram

If you haven't got too far, it may be best to reassemble and order one.

You could push on but if there's wearing on the sides of the circlip, you shouldn't use it.

Bit of a coin toss which option to choose

Funny enough I haven't got that far. Got as far as trying to remove wheel sensor and it seem not want to play politely as yet.

Hmm, seems the part, the circlip, is not available through Partsouq either.

[Two Emms]

Well that's not ideal

Maybe you can get one from a mitsy dealer

Depending on how soon the vehicle has to be back on the road, l'd be tempted to push on and hope the circlip is ok. If you get to it and it's worn, deal with it then.

Even if you can't get a "genuine" one, it may be a standard size. At least with it in your hand, you can measure it up.

I'm one of those fortunate people that have a work vehicle to get around if I get caught out.

Currently trying to get the lower control arm bolt out. The online service manual states to use a jack under the control arm to compress the spring, however it seems as I do that the bolt is still firmly in there. For my mind I cannot see how that helps with getting the lower control arm bolt out?

It does help with getting the lower strut bolt out though.

Edit: Sorted have both lower bolts out of the lower control arm now. Work on the rest tomorrow.

Have look at this vid. Might be helpful when you refit the lower arms. Watch for how he uses a strap to pull the arm forward.

If you have previously fitted rear springs, you're probably aware of this trick but I just thought it worth a mention

Thanks for that. I didn't do the shocks myself, so I haven't but I do remember reading something to that affect with the strap. The highlights it though. Thank you.

Hmm, this is probably a stupid question to ask now, considering where I'm up to, but for the cv shaft spline to come out of the hub and the the diff end spline come free from the diff, does the vehicle need to be in neutral with the handbrake off?

I've got everything loose on the hub knuckle apart from the toe in arm.

I can get the shaft to move inward from the hub however I can seem to get to move any further, than what's shown in the pictures.

[Jasonmc73]

I've never removed the axle mate but maybe remove your hub, if the axle don't wanna come out of the hub?

Presume you found this below

& that pesky inner snap ring circlip may also need to fight with him to remove from the inner according to workshop manual.
