Leaky rear axle shaft, 80 series

Post by mada1234 »

I replaced my oil seal on the rear of my 80 series a few weekends ago and the bugger is leaking oil again through my bearings and onto my handbrake shoes :?
I also had issues with the same thing with my old 60 series,, i ended up replacing the 60's axle shaft as it was too far worn to seal properly.
I couldnt see/feel any wear where the seal seats around the shaft so i didnt replace the shaft,, but its leaking again....
Is there an oversize seal that can be used here?(i obtained o/s seals to put in my 60 series diff where the tailshaft/yoke goes into the diff), or has anyone got any tips tricks ideas suggestions when replacing this part..
Any advice appreciated ,,,,, Mada1234.

you can speedisleeve the shaft. is the wheel bearing adjusted properly? any slop will allow the seal to leak.

the bearing was a tad loose,, pullled it apart today.
I guess that when i put it all back together the other day, the new brake pads made me think there was enough tension on the bearing adjusting nut.
ive got a new axle oil seal (and a inner dust seal as well to replace today as it has been fouled heaps,, so its probably suspect too!!)
ill see how i go over the next few days as im heading to ballarat tomorrow, so if it leaks again ill know by the time i get near melb/barrarat tomorrow morn and i suppose ill deal with it there if need be.
thanks again... P.S. any other suggestions are welcomed from anyone as this is really pissing me off!! :bad-words:

THANKS ALL MADA1234

its best to remove the caliper and disk/drum when adjusting the wheel bearing so you know you've got the preload correct. the little seal is difficult to get correctly aligned and is easily damaged, too. it's a good idea to get genuine or Japanese genuine-equivalent seals, the taiwanese jobs are more difficult to install and will not last.

good luck.

All seems good, 500 odd kms later mostly highway and it seems ok.... :D
when i did it yesterday i had the caliper off, but not on purpose,,, ill remember that for when i have to do the job next time. those small oil seals ARE fiddly, they seem to move by themselves if they aren't seated true.. i found i can press them in by hand with a large socket(fits perfect!!),,then i can see if the socket lines up straight..
Thanks for the suggestion about the bearing tension,,it seems you were right!!
Cheers,, MADA1234
