Diff Oil Leak

[Seasider]

Could this be the cause ??






Not dripping/oil marked, its a leak when running!!!! mostly over the back plate & offside of the diff

Re-sealed the back plate & new drive shaft seal...

I have a horrible feeling thats not the problem & its a crack in the casing or back plate but i cant see any...

Bump for the morning crew

How about fitting the seal a tiny bit(1mm/2mm) out from where it should be, so the groove does not line up with the lip of the seal but still seals properly externally?

I have done it in the past on a different application, worked a treat for me.

Just a thought and a free bump

[Seasider]

Not a lot of margin on seal seat & I’d rather sort it properly if I can…

More trying to find out if this would cause a big leak or if i've got a crack

Appreciate the bump & your thoughts

Never seen a crack on a diff that wasn't obvious after a wash(the diff ) - if you know it is coming from that seal could there be too much movement laterally on the shaft - bearing wear etc forcing a good seal to leak?

ETA which flange are we talking about here?

Off-side drive shaft...

As there is a real shortage on input so far.......

.......if you have established a good seal fitted correctly won't cure it and that is defo where the leak is - anything wrong with shaft, vibration due to CV(?) causing lateral movement in bearing - leak.

and another bump in the interests of a better suggestion

[Seasider]

New C/V's fitted as the others were worn, not massively but slight rotational movement. not that much movement on the shaft so don't think the roller bearing are shagged enough to cause it...

That must be some lunch

Any thoughts on this one?

Have you tried dropping the diff on your finger?

Hope this helps

It trapped my finger & fell on my arm & no not really

A decent local engineering shop could crack test it with dye or ultrasonics.... It can also be welded up and reground if it's made from unobtanium

I'm just really hoping it isn't as i dont want to pull it out again !! Actually its more the put it back up

Can you dim where the lip sits? If it sits in that groove I'll bet you at least five pounds that'll be your leak If it is that's certainly repairable.

Can this be done sensibly working off the ground with some decent stands etc, as in no lift?

Talking Chim here(but probably similar), are we talking skid pan off, exhaust off, anti roll bar off, prop end off, shaft ends off, sensor off?

Does the diff(BTR on mine) pass through the chassis rails with both speed sensor wheels on(looks wider)?

Any surprises?

[Seasider]

On the train at the moment so a basic reply.. Yes, but !!.... I've done it twice now (would be easier with 2 people) ETA It would help if you have a degree in wimins bits/delivering large packages through small openings

Tried a new seal slightly further outboard still leaking

I'll settle for a beer Rob


Looks like its out again and the spare back in


Ribol give me as shout when you need to get yours out

I'll talk you through it, because i doubt by then i'll ever want to see another one again

Never mind give you a shout, having looked under there I am seriously considering giving you the keys - before I go on holiday

Is your diff like mine(BTR)? The distance between the chassis rails seems tight for it to come out with the sensor wheels on, is it an optical illusion?

BTR...

Lift, push forward, Twist, Rotate & straight out through the rails


The reverse ain't as easy

I'm away the same time as you
