Inner axle seal replacement and front diff centre removal

[Bidja]

Time poor at the moment. Leaking inner axle seal (pass side), for on 3 yrs now but not a bad weep through knuckle scraper seal. Yeah best to do a both side full rebuild but prefer to just do inner seal for now _ no oil drip on rim dish or floor (looks messy), but live on a dirt road and she has not had a wash under for more than 12 months. GU 220k kms replaced bearing 100k km back tracks well/stable.
From those having such experience, what about doing inner axle seal only and see how swivel hub rear scrapper goes?

Pic of both sides as comparo.

Planning on fitting Harrop E- locker at same time and thinking of removing diff assy (25 + kg) by myself, is this too heavy on my own or should I give it to w/shop and they could pop the inner axle seal at same time_thoughts/safety appreciated??

Getting w/shop to install locker into diff center.

Diff guts are easy enough to hoik out single handed.

for the time you're going to spend doing the rest of the things, a swivel-hub rebuild will not add much in cost or time. And then you don't have to think about it for the next 30 years or so.
While you're in it chuck some chromoly CVs and half-shafts in

Bastard of a job. If you are not a body builder, I suggest you get help to refit the longer drive shaft and c.v. You do not want to drag the heavy bugger across the new seal as it slides in.

Axle seal is easy to do, but its a long process, as everything on that side needs to come apart. If you haven't get yourself a seal drift set. Cheap to buy and so bloody handy when doing those axle seals.
Use these seals when doing the job.

Apparently the ducks guts they are.

Thanks fellas for the replies.

I have all tools for the job, the only thing missing is a press but did wheel bearing a few yrs ago and can access one (local mechanic) if desperate.

Even bought a ball joint separator from Repco the other day _ always wanted one of these anyway.

Removed the axles some years ago, greased CVs and cannot remember why, maybe was convenience when I changed out the rotars/whl bearing. Interesting though , it is the longer axle with the failed inner axle seal.

Not too concerned getting amongst it, but the weight of the diff is my concern and no one around to call on to give a hand.

Have some genuine inner axle seal on the shelf (had them for a couple of yrs) and yes the trail-safe have good reputation _ will see.

DIY troll time _ Just other jobs taking priority at the moment _ weighing it all up.

Was mainly interested in the chance of the s/h wiper seals holding back the grease if no oil present.

Thanks again.

That ball section John where the wiper seals run. Many moons ago I spent a lot of time rubbing them back with some wet and dry and filling in the divots with metal filler, and more sanding. Worked really well but I think it’s time they need to be done again. It’s been a while….

I changed out the rear diff, years ago, by using a trolley jack to take all the weight. If I had to do it again, I would weld a special cradle to hold the diff on the jack.

This.
It helps even to break it apart from the housing, to jack a bit close to the pinion; easier than trying to use a pry bar.

The axle trunnions surface finish appears to be in good condition just need to clean up area and have a look. The black paint finish has worn off defective side as the dust / dirt mixing with the weeping lube now a honing paste. Most likely hub seal kit - might have to wait a bit..

Jack/Cradle of sorts will help support/manoeuvre.
