    GQ front hub grease leak

    afternoon everybody, new to the forum here. ✌��

    just chasing my tail over this grease dribble i’ve got on the driver side coming from between the stub axle and dust cover. i have replaced the seal twice and both times it has been dry for a day or two and then goes back to what’s pictured here. it’s got me stuffed, i did the entire front end about 20k ago, the leak doesn’t smell/feel at all like diff oil & is very sticky like grease once cooled off. i’ve had 0 issues with the passenger side since i did the front end rebuild and i did it exactly the same as drivers.

    the seal is seated all the way in the rotor and facing the correct direction, i think there’s a chance i’ve put too much grease in the bearing assembly but other than that i have no idea.

    i also believe it looks runny from sitting on the highway at 100km/h + today for around an hour. any know-how or advice would be greatly appreciated! cheers ��

    Hi mate, i saw your post on FB. You said there that you packed the swivel hub solid with grease? Is that correct? The main body of the swivel hub is an Air Void mate and does not need to be packed with grease
    It is possible that as the grease gets warm it is pressurising the hub ans blowing out the scraper seals.

    Initially I was going to say inner axle seal but the leak is from the wrong place for that.

    Drop out a bolt from the lower King pin bearing, if oil doesn't leak out then you are looking at Grease and not a diff oil leak. In which case too much grease is your problem imo.

    The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

    Get a bit of the seepage and give it a sniff. If it pongs like diff oil, as MR posted then go deeper. My Patrols hubs have always seeped a bit, even with new seals, just par-for-the -course, but packing in too much grease is a common mistake.

    Which grease did you use?

    Only because I was nuffy rooting around installing an air locker a few weeks ago first time on an old GQ I believe it could possibly be your seal between the stub/spindle axle?As others have kindly suggested they are a relatively dry CV joint and the most common leakage symptoms are from a simple failing axle seal down and out through worn scrapers on the axle housing. It is strange how your leakage (grease or oil either way) appears to be coming from the opposite than usual side and should honestly demand a further wheel/hub/disc complete removal to assess its integral stub/spindle axle connection is ok

    Scratching my nuffy head again a little bit SussGQ Mate! There’s no chance you are running the old girl at 100kmph with your manual hubs locked in too Brother?

    cheers for the reply mate, i didnít pack the air void in the cv no, just leading to believe iíve packed too much into the wheel bearing assembly.

    i was following the manual, which stated to pack the gap between both bearing races once theyíre in the hub, but apparently that doesnít need to be done.

    iím going to pull apart and redo with just the bearings packed & a smear over the grease seal lips tomorrow and see how that treats me!

    itís definitely grease, doesnít have that distinct rank smell of gear oil. it never did it before i replaced the seal which is why iím pretty sure i e put too much grease in the wheel bearing assembly

    i used Castrol HTB2

    will do mate! i did accidentally leave my hubs in a while ago for a few weeks of highway driving lol

    it was already leaking grease beforehand but i assumed that wouldíve ruined the seal, so i replaced it again about a week ago but still to no prevail.

    it was chockas with grease both times though so iím 90% sure thatís my issue

    update on this, apologies it took so long, wasnít really on my phone over christmas/new year! so iíve removed the kingpin bolts and every single one was bone dry. it doesnít smell/feel at all like diff oil on the dust cover, so next is to pull the hub and rotor off again to repackage with lots less grease. cheers boys
