Front wheel bearings screaming

I replaced the driver side bearings and rotor about 4-5 weeks ago and for the past 2 weeks they squeel on and off. It's getting worse.

I have taken the hub off four times in the last two weeks to check everything over.
I found this:
The inside of the outer bearing had burn marks on it and the spindle had a light discoloration where the bearing rides.

I tighten the nuts per the manual in the way it says.
50 foot pounds on the first nut, back off 90 degrees, put on the washer observing the hole and pin. Then the outer nut and tighten to 160-240 lbs.

Today I put a new outer bearing in.
The squeel is still there.
Does it squeel because it is to tight or to loose? Maybe another reason?

Don't know how you guys are but not having my truck really gets me down. I hate having something wrong with it.

Matt.

I set my bearings with the wheel on...I torque to 50 ft lbs to "set" the bearings. Then I back it off until the wheel spins well and there is no play. If there is play, tighten until there isn't, check to see how it spins. Having the wheel on makes it easier to check for play and to see how it spins.

I agree with rolsmojave3, make sure you properly seat your bearings, and are you sure you got the right bearings for your truck? i had trouble getting the proper parts for my truck when i rebuilt the front end.

As far as I know I have the right bearings. I took the bearings in and the guy behind the counter read the numbers on the bearings to get the right ones.
I also had problems getting the right ones at first.

I took back apart yesterday and found that the pin on the inner nut had sheared off. I bought a new one from Oriley's for $21.00. It's back together now but I still heard it squeek once.
Guess I'll keep an eye on it.

I have another question but I'll post it in a new thread.

Thanks.

I've been driving it for a couple of days now and it seems to be okay. I think I just had it to tight. I always seem to learn the hard way.

160-240 lbs on the outer nut? dang... I go 50 on the inner, and back it off 90* and torque the outer to 100. I've never had any problems with mine coming loose, they spin freely and dont squeak.

Lately I've had more problems with them squeaking. It happens more when I make left hand turns or hit a bump. It will go away then come back.

They are packed with grease.

I don't understand what would make the outer spin on the spindle. That's what the barrels in the bearing are for, right?
