Hi Guys
Have a seaping front diff main seal where drive shaft mounts
I note it has a split pin retained flange
Has anyone successfully changed the oil seal with the diff in the car?
Or does the whole diff have to come out?
Any tricks?
Cheers

I didn't do it myself but had a garage do it for me. Diff stays in the car....... got a seal from local bearing company (info on this group somewhere)

BUT...... its still leaking !

Leaky pinion seal....
Welcome to normal Bellett life

Hi J.

The number for the seal is. 17446 in Flaseal. P4768 Repco/PBR.
Now. This the tricky bit. From what I've found the 2 Companys either don't exist and/or
are no longer being manufactured. The bearing company may be able to crossover the numbers to
a seal of another brand.
I sent my GT diff to a specialist in Brisbane and they sourced all 3 seals from their local
bearing comany. They had a sample seal and supplied the dimensions of the housing and the pinion
drive flange to them. Procuring them was not a problem. Getting the side carrier bearings was.
If you have a slight groove on the pinion drive flange. Enquire about a speedysleeve and purchase
some 2 pack araldite to glue it onto tne flange. If they haven't got the parts they may be able to
buy them in from another branch and you pay for the freight. Sometimes they can add to an order
and you may have to wait a while and not pay the freight.
If the seal is either 1 mm under or 2mm over in thickness. Don't dispair. As long as the seal runs on
the flange, which it should do, as the seal sits in the housing and has no bearing on the tension or
freeplay.
Keep us informed. No doubt you will. Happy hunting.

Hi Dave
thanks for this info - solid gold
I went into my local driveline shop today and showed them a picture of the diff
'No problems mate, piece of piss'......' do em all the time'
Ha, we all know where that is heading hey


I am planning on getting the brakes serviced later so will add this to the list. Luckily the brake shop and driveline shop are neighbours

Cheers

Thx for sharing J.

No probs. J. We see this at work quiet often.
We had a young fellow advised by his "backyard mechanic" that he would put a new seal
onto the rear main crankshaft of his diesel engine but will need an extra thick gasket to have
the seal run on a good surface. This particular seal is mounted in a large bracket and
doesn't have a gasket, only sealant. There were some swear words said that I've got in my black book.
I agree. Good invention.

When you start on your brakes keep us posted.
I know a couple of 'tips & traps'. Especially on the rears. A 6 foot chain wire fence is a good
hand brake.
