Thread: Ashcroft HD CV shafts and front diff seals - leaking?

You cant blame Ashcroft for leaking hub seals

Seeing the D2 has driveshaft seals not hub seals and the OP has Ashcroft HD driveshafts I'd say it it's a fair question to ask.

d2 ball joint issues will create leaks too...

I'm waiting on the new parts from the UK (hub nuts, seals and top and bottom ball joints), but, I just found this thread, < Front axle seal - Page 2 - DiscoWeb Message Boards > which made for interesting reading (particularly p. 2).

Note the comment by seventyfive (emphasis added):

post a picture of the half shaft so we can see where that metal dust shield is on the axle. If your dust shield flange isn't almost all the way against the seal that could be your problem.

WHICH Is the giant issue I have with Ashcroft front D2 axles.....if that flange isn't a tolerance fit on the axle it moves out towards the CV and leaks like a sieve.

The pictures posted up near the bottom of the page by listerdiesel are great for showing how the seal works, including the secondary seal on the flange.

The Ashcroft shafts don't include the flange part, this has to be transferred from the old shafts. I suspect this may be where the issue occurs.

The lip touching the flange is to assist keeping dust out and away from the inner lip...

There are 3 sealing points on the oil seal, 1 internal (keeps oil in), 1 external (keeps dust and water out) and the 3rd external is to keep dust away from the main external face.

It (the outer soft face) isnt there to stop any grease or oil.

Are hub bearings 100% I know the amigos should tell you a bearing
is on its way out but bearing wear may have an effect on the seals.

I don't know. When I removed them 6 months ago when I fitted the new diff centres and shafts, they seemed fine, I couldn't feel any play in them. JC also had a look at one and didn't see any issue.

I have been getting the three amigos caused by the rear left wheel a few times.

Maybe I should just change them while I'm back in there...

In 6 months my seals on both sides have started leaking (spraying oil on the inside of the wheel and tyre) and now the passenger side is dumping oil out if the vehicle is parked with it on the lower side.



I used a genuine Land Rover front drive shaft oil seal on one side and a cheapo pattern on the other, but both are leaking.



Going to pull it apart and redo, but was wondering if anyone else has experienced this - i.e. is it a side effect from the Ashcroft product?

I have them fitted but no issues so far
