Pulled off the wheels to do a full checkover before going over the pits and found oil all over the LHR drum/axle tube. Brake master is full so Im thinking its not a wheel cyl leak. Is there a seal that stops oil running down the inside of the axle tube from the gearbox? Thanks in advance

Hi

the Oil has to flow down the axle tubes to lubricate the rear wheel bearings...

so, You need a new rear wheel seal kit: part no: 311 598 051
contains: oil seal- large & small o rings- gasket- washer and split pin..

and You also need to refill the gearbox with oil...
Hypoid 90 gear oil

cheers

Save yourself a hard task of trying to get the rear hub nut off 36 mm. Go buy or borrow the right socket in 3/4" drive no smaller!!! And at least 5 foot of firm ( not bendy) leverage. Once you have that the hubs will be off in under five minutes

Mine went BANG when I was jumping up & down on 2 metres of water pipe over a 3/4 breaker bar..

snapped off a new 1/2 inch sidchrome breaker bar...

to do the 36mm nut up to the required torque...

use the 2 metres of water pipe [or about 5-6 foot]
to tighten it...

if its not done up that tight , the brake drum will move on the axle splines which eventually will wear the splines on the brake drum away...

cheers

get 4 of the axle seal kits.....they can be a bit ricky to get the hang of, hence the spares.

may as well do the axle boots whilst the oil is out of it (get GERMAN ones!!!)

everything is on its way from CIP, I still cant believe how much cheaper it is to do up a bug compared to a Torana or Kingswood!!!

Now Torana etc parts are rare wheas VW parts are still being made..
VW parts were much more expensive 10+ years ago when most parts were NOS and rare...
Now they are being made again... lol

VW Seal kits are very cheap from the USA...

Get an Empi whack spanner. It's designed to be hit with a big hammer. Do not have the gearbox in gear. You don't want that energy in the gear box. Have the wheels on the ground and the hand brake on. Then hit it really hard with a really big hammer.

If your wheels have a big deep dish, fit a stock wheel there. You'll see why.

Also use lots of Aviation Goo all over the gaskets and other bits when you put the new seal in.

if You use the hammer and tool on the nut...

How do you get it back to specs...>??

when You replace the nut...

as they need to be done up very tight

something like 217ft lbs or more...

back to a 5ft piece of pipe on 3/4 drive bar...

I always use Pematex gasket cement or similar on all Gaskets..
both sides..

Very useful info (regarding retightening the axle nut.

I am halfway through the same process, I am having trouble removing the outer spacer. Not sure how to tackle this.

Any tips would be helpful. Thanks.

There's no need for a 5 foot length of bar to go to 217ftlb.

Most 1/2 drive torque wrenches go to 250ftlb and are about 2 feet long. With moderate pressure it's very easy to do them up to a small torque like 217ftlb.
