Wheel/Brake/Bearing Question

A small amount of bearing play is normal and required on a trailers axles. In fact bearing will last longer with a small bit of play. Bearings should never be tight.

This from Dexter on "bearing adjustment and play".

Bearing Adjustment and Hub Replacement
if the hub has been removed or bearing adjustment is required, the following adjustment procedure must be allowed:
1. After placing the hub, bearings, washers, and spindle nut back on the axle spindle in reverse order as detailed in the previous section on hub removal, rotate the hub assembly slowly while tightening the spindle nut to approximately 50 lbs.{t (12" wrench or pliers with full hand force).
2. Then loosen the spindle nut to remove the torque. Do not rotate the hub.
3. Finger tighten the spindle nut until just snug.
4. Back the spindle nut out slightly until the first castellation lines up with the cotter key hole and insert the cotter pin (or locking tang in the case
of E-Z Lube TM).
5. Bend over the cotter pin legs to secure the nut (or locking tang in the case ol E-Z Lube TM).
6. Nut should be free to move with only restraint being the cotter pin (or locking tang).

And proper bearing end play;

Nev-R-Lube Bearing End Play inspection.
The following lists the maximum axial end play for each of the sizes of, Nev-R-Lube bearings and the amount of tilt that can be expected, Since there are a large number of wheel and tire combinations in use on trailers, the tilt is expressed in inches per inch. The movement as measured at the tire tread can be found by the following method:
Example: if the tilt value is shown as .003" per inch and the tire measures 30" in diameter, simply multiply .003' X 30' = .090" which is the total expected movement at the tires' outer diameter.

Bearing size End play resultant tilt value
35 MM .005" axial .003'7 per inch
42 MM .006" axial .005"/ per inch
50 MM .O08" axial .004"/ per inch
