| GRinding at low speeds
Hey guys, thanks alot for getting me started again, now I've noticed a griding from the right front wheel when turning at low speeds, it doesnt sound like a click of a cv joint, does the swivel ball get lubed externally (either from a nipple or fitting of some sort) & will this lube the wheel bearings? I'm going to jack it up and check them as per a previous post, I dont think it's the locker, but I'm not sure. also, what do you do when the swivel ball leaks a muddy brown fluid? is the front rear end axle seal shot? What kind of oil does it take? normal 80w90? what kind of grease for the wheel bearings/swivel ball/cv? Thanks alot. |

Heh, I see how it's done on clubwagen, way too many special tools required... axle holder, seal & bushing drivers, I could fab them all up, but unless I'm going into business, I think the garage is going to get to repack the bearings... thats saying thats what it is..... |

Actually, the front axle is almost like my 1983 toyota pickup front axle..... pretty much the same except for the hydraulic locker.... |

The swivel balls are about half filled with multi-purpose grease through a port at the rear edge. Turn the wheel away from the side you want to inspect and remove the 19 mm plug. The axle itself gets 85W90 gear oil. See previous posts here for what other folks use.
A muddy brown fluid could be a lot of things, as could the grinding on turning. The grinding is probably a failed or failing wheel bearing, which is allowing the brake caliper to rub.
From all of the problems you're bringing to the table, it sounds like your G's previous owner(s) didn't maintain things very well. |

There's really only one tool involved; and don't even think of just repacking the bearings! Replace them along with all the seals. |

well... the previous owner I dont think they knew what they were doing... many stereo parts & harnesses left laying in the dash but no stereo to hook them too... lots of hole drilled in the firewall for cables & wires and crap.... I'm fairly competent with this stuff but I know to go see a pro when I can't figure it out..... some people shouldnt be allowed under a dashboard.... anyway enough of my complaining.... I really have to get this thing fixed.... so only one real tool huh... is that the inner seal driver? or the hub holder? or the cap remover/installer or the outter nut socket? |

The only specialized tool is the one needed to turn the nut on the end of the axle. You can make one yourself from a 1/2" drive socket. The exact size you need would need to be deterimed by taking off the hub cap (it's dry in there, no lube). A little turning and some grinding and you are good to go. Buying one is easier. |
