    Gq front diff issues

    Hey fellas got a gq ute have had it for 4 years and keep going through wheel bearings and swivel hubs from what i am presuming is a bent diff. Car has developed a mad wheel wobble now and after having the bearings and swivel hubs done in January passenger one is leaking oily grease badly. Tightened the bearings but still mad wobble (panhard bushes aren't that old either) is my best bet just to find a decent secondhand diff? And maybe transfer my good brakes etc over to it? Sick of getting the bearings and swivel hubs done but at the same time I don't want to risk buying a second hand diff and potentially have the same problems?

    When you had the swivel bearings done, did they check the force required to turn the hubs left and right? It should take 6-17 N of force to move them.
    My swivel bearings have had no shims since before I bought the vehicle, so I assume they were removed to help stop the common death wobbles. As for the leak from the seal, it can be caused by having too much grease in the assembly.

    Check that your steering damper isn't worn out as this will allow the wobbles to develop as well.

    Are the tyres wearing out the inner or outer edges?

    My advice is: not to follow my advice.

    Have you had the wheel alignment done?
    If the camber angle is off, that is an indication of a bent housing, if you ignore the other causes of camber angle issues.
    There are few DIY methods that you can use to check whether the housing is bent or not, but usually it needs you remove the axles on both sides.
    For a front axle, that is quite a job.
    If you buy a used one, make sure it's straight by using a straight bar or similar method.

    King pin bushes? have you checked them
    They will do exactly what is happening to you specially if one is shimmed and one isnt as It puts the knuckle out of square ( makes axle sit hard and top of bottom of axle seal) etc etc
