i have a 2002 f350 sd i had a bad wobble in front end, had rotors turned replace pads, now a bearing went out replaced spendal but i have the same problem the right side tighten up and i back it of a little the drivers side won't tighten up tight enough to stop the wheel the first time i just tighten it up as far as i could and now the bearing is shot and is doing the same
need to get it going for my work in 7 hr. lo0st big time today
is there any body out there that can help
You don't want to tighten the bearing to the point where the wheel won't turn. That will cause bearing failure. You have to preload the bearing. I don't have the specs here and it varies by appliication. Usually, you tighten the bearing using a torque wrench and rotating the rotor. Sometime that's all you do and other times you back off the nut slightly. Generally if you snug the bearing while rotating the rotor and back off the nut a tad, will put you in the ball park. When you get done, the rotor should rotate smoothly yet not have any in and out movement. Grab the rotor, top and bottom, and try to rock it. There should be almost no rocking movement. If you can't tighten the nut enough, either you were given the wrong parts or something is missing.
Look in a shop manual or Chiltons/Haynes. Most of the heavy trucks require you to torque it really tight, I think my 94 F250 requires 200 foot pounds. Then you loosen it up and then retorque to around 50 foot pounds. Be sure to check manual for torque, it may be way different for your model.
You know what else might be the problem? He might have installed new bearings without replacing the races in the hub. Since the bearings and races come as a matched set. If I remember correctly, you can't put the new bearing in an old race.
If it's a 2wd, you have to torque the Jesus nut but very little. You torque it to 21 ft/lbs while turning the rotor forward, then you stop, let the Jesus nut out 180* and then tighten to 18 ft/lbs again. That's a fairly light amount of torque. He's gonna have to take the rotors to work and use the old 30-ton press to get the old races out and press the new races in. (Remember which is the inner race/bearing set and which is the outer.)
