Leaking diff oil ! ! ! Need help !

Post by **SWAMPRR** » Mon May 09, 2005 10:30 pm

hi i was just wondering if anyone has had this problem b4 ? i was leaking diff oil out behind where the spindle bolts onto the cv housing (For ages !) ...and i pulled it all apart and found it was a bad seal - almost nothing left !

so i got a replacement seal but noticed that the diff oil had leaked into my cv where i thought was usually packed full of grease but mine had very little and allot of diff oil...

my question is is there a seal inside around the axle that stops your diff oil flooding into your cv joints? or is there somthing wrong here...i noticed some brass washer type things that look like they do the job sorta?

NEED HELP ! ! !

i think from 86onwards there was a seal in the wheel bearing nut to keep oil out of the wheel bearings,which were packed with grease.the earlier ones had no seals and ran diff oil through to the bearings.

Yep
There are 2 seals.
A hub seal and an axle seal.

I'm not sure of the purpose of the axle seal.
It either stops diff oil getting into the swivels or swivel oil getting into the diff.

I recently replaced mine because the swivels were draining into the diff, and overfilling it.
(did the bearings, swivel [ball] seal, hub & axle seals while it was apart)

Most people remove the seal between the diff and the CVs. It allows the CVs housing to vent and reduces the chances of running the CVs dry. The normal level of oil in the CVs is higher than the axles. It does not seem to matter. The normal method is to overfill the diff slightly.

What happens when you are on a 30 degree (arbitary figure) sideways slope.
Wouldn't all the oil drain to the lower hub and the upper hub be dry?

Hilux (and many other) CV's are filled with grease. Rover are filled with oil (usually).

NO - To drain to the other side, the oil in the hub on the high side has to flow upwards to the drive flange, before it can then flow down through the stub axle into the swivel housing, then into the axle tube.

Any slight movement of oil would only be temporary, and enough would stay there to provide lubrication.
