Hello I need some help figuring out an issue on an 79 chevy 3/4 ton 4x4. Last winter I had the wheel bearings on one front hub go bad and didnt realize it until I about lost the wheel. The only thing holding the wheel on was the brake caliper. I replaced everything- Hub, rotor, bearings, seal, spindle nuts and lock-out. Now I have noticed that there is grease very slowly oozing out between the hub and the lock-out. Surely I couldnt have over greased the bearings right? I dont drive it very much, but it takes awhile for the grease to show after I wipe it clean. I would say that I have driven the truck 300 to 400 miles and wiped the hub twice. Any advice would be great! Thanks Oh one other thing. I have had problems in the past keeping the lock nuts tight on the front hubs. If I remember right, the book called for 175 to 265 ft lbs of torque. I dont have a wrench that goes that high so I used a 3/4 inch breaker bar with about a 3 foot cheater bar. Is there something I am missing as far as keeping them tight? Thanks Again

Sounds like a bad O-ring between the wheel hub and the locking hub cover letting the grease out.
Book spec I recall is 150 ft-lbs on the outer wheel bearing locknuts. I like to go a little tighter like around 225-250 or so. 150 is usually sufficient for it to stay tight on a D44 or 10-bolt front axle however, I'm thinking you aren't getting them tight enough if they keep loosening.

Alright thanks for the response. I will check on the O ring. I will keep my eye on the lock nut as well. i didnt know if I was doing something wrong maybe? The last time I tightened that nut, I used a 3 ft bar ontop of the breaker bar. Hopfully that does the trick. Thanks again!

Just have to tell you. If you are gonna do your own repairs invest in, and learn to use a torque wrench. Loosing a wheel could be dangerous to not only you or your passengers, but to anyone near you.

lol thanks chuck I understand what you are saying. I just dont have a torque wrench that will measure 250 ft lbs. I was able to torque the nut to 150 because my wrench will measure 150 which is the low side. I put the extension on just to get a little more torque. I will stop by at a buddies shop to get the big wrench if this happens again. Believe me, I dont want anyone hurt, and have been checking that wheel often.
