AXLE MAINTENANCE
The axle and its attached parts—bearings, hubs oil seals, brakes, cam shaft and slack adjusters—are all
assembled and are engaged in mechanical motion and require frequent maintenance. Preventative
maintenance on the axle can save on repair bills and prolong trailer life.

2.1.1
WHEEL BEARING/SPINDLE NUT ADJUSTMENT
To correctly check and adjust wheel bearings, the axle must be supported so wheels are clear of the
front and free to roll.
As standard equipment, LUFKIN employs the use of a one-piece spindle nut. Procedures for
installation and wheel bearing adjustment may be found by clicking on the links below.

INSPECTIONS
2.1.3.1.1
Inspect condition of sight glass on hubcap; it should be clear and not
discolored. Change in color could indicate excessive heat. If cap is hot to the
touch, lube level in sight glass at proper level if oil is used.
2.1.3.1.2
For grease with solid metal cap, remove access cap and inspect for
presence of grease.
IMPROPER BEARING MAINTENANCE AND ADJUSTMENT CAN
RESULT IN OVERHEATING, WHEEL LOCK-UP, AND LOSS OF
ENTIRE WHEEL ASSEMBLY CAUSING A CRASH AND POSSIBLE
LOSS OF LIFE.
