Trailer Wheel Bearing Issue

[Bobby DiDomenico]

Rick,
I'm not familiar with these, is there an inner and outer bearing?
If so, when you replaced the outer did you replace the inner bearing assembly as well? IIRC if the inner one is somewhat loose might it cause the outer one to move and have cage failure?
I hate roadside repairs!

It is a 8,000 Dexter axle with a larger inner bearing and a smaller outer bearing.
Both bearings and hub replaced each time.

One thing Dexter recommends is to torque the bearings to 125 ft lbs before backing them out and setting them with only finger tight and backed off to get the nut lock in place.
Basically zero slack in the bearings cold.
I have not seen this in black and white just the recommendation from one of the reps.
I have always set mine close to a flat on the nut loose once snugged up with a pair of channel locks for the last 40 to 50 years.
Yes I am old.
Thanks for the input.

I had a problem with a different trailer than what we have now a few years ago, the rear axle bearing on the same side would run really hot so hot it would burn you if you held your hand on it. I repacked the bearings and it would still run hot. I knew it would be just a matter of time until it would fail. I pulled the hub removed the bearings even the seal and back bearings completely washed all the grease out and repacked the bearings with a good high temp grease rated the highest I could find and from then on the hubs run cool I could hold my hand on it after several hundred miles.
