Using a dial indicator check the end play on the rear wheel bearings. Set it to 0.0050 inches
That's a bit tighter than stock, stock spec is .008*.018"
Using a beam style torque wrench set the front wheel bearing pre-load to 125 inch pounds whilst spinning the rotor-after seating the bearings of course. INCH pounds.
That's half the procedure and the spec is off. Per the 72 Plymouth FSM, other years similar.
Adjustment:
(1) Tighten wheel bearing adjusting nut to 90
inch-pounds while rotating wheel.
(2) Position nut lock (Fig. 10) on nut with one
pair of slots in line with cotter pin hole.
(3) Back off adjusting nut lock assembly one slot
and install cotter pin. The resulting adjustment
should be zero (no preload) to .003 inch end
(4) Clean the grease cap, coat inside with wheel
( 5 ) Install wheel covers and lower vehicle to floor.
If you tighten to 125 in/lbs and leave it there, you'll be back doing new bearings.
