    No I mean the hub nuts. You know after you take out the hub. there are the nuts that are in the axle houseing or something like that. You use a hub socket on them to get them out and to tighten them. They keep coming loose.

    Yes, and yes. The pin is in the inner nut and I have the lock ring with the little holes in it and the hole is lined up with the pin I made sure of that today. and nothing seems to be broken.

    Does the tab sit in the notch good? I have seen it sometimes where the corner of that tab will wear and allow the ring to spin.

    Another thought

    How are you setting up the bearings torque etc. Are the races pressed all the way in?

    The ring seems to be fine. there is a little play in it but not much. The inner nut I set at 50 lbs then turn the wrench 90 degrees and then tighten it back up to 35 lbs. then put the lock ring on and tighten up the outer nut to about 95 lbs. and yes all the races seem to be fine.

    How loose are they getting? I have taken mine apart before and they weren't tight, but they really hadn't backed off, and there was no play in the hub. Is there any indication that the lockiring has spun on the spindle? if not then the nuts aren't backing off. i would check the races and make sure they are both bottomed all the way.

    I can jack the front end of my truck up and the tire moves back and forth and side to side. and no it is not the ball joints it is the hub nuts becasue when I tighten them up the wheel stops moving.

    Well I just talked to a buddy on the phone and He said that the threads on the outer hub nut might be bad or on the spindle. So tomorrow I am going to go and get a new outer hub nut and see if that helps.

    I don't think this would cause the problem, but you're missing the last step. :eek1: You're supposed to back off on the inner nut about 3/8's of a turn after the last "torque" step. Factory spec calls for about .008's inch end play after the outer nut is tightened. By torqueing the inner nut to 35 lbs. and then also torqueing the outer nut, you're running the wheel bearings WAY too tight. :o
