„

After removing the dust cap, cotter pin, spindle nut and 

spindle washer, remove the hub to inspect the bearings 

for wear and damage.

 

„

Replace bearings that have flat spots on rollers, broken 

roller cages, rust or pitting. Always replace bearings 

and cups in sets. The inner and outer bearings are to 

be replaced at the same time.

 

„

Replace seals that have nicks, tears or wear.

 

„

Lubricate the bearings with a high quality EP-2 

automotive wheel bearing grease.

Every time the wheel hub is removed and the bearings are 

reassembled, follow the steps below to check the wheel 

bearings for free running and adjust. 

 

„

Turn the hub slowly, by hand, while tightening the spindle 

nut until you can no longer turn the hub by hand. 

 

„

Loosen the spindle nut just until you are able to turn it 

(the spindle nut) by hand. Do not turn the hub while the 

spindle nut is loose.

 

„

Install a new cotter pin through the spindle nut and axle.

 

„

Check the adjustments. Both the hub and the spindle nut 

should be able to move freely (the spindle nut motion 

will be limited by the cotter pin).

never crawl under the trailer unless it is on firm 

and level ground and resting on properly placed and 

secured jackstands.
The possibility exists of the trailer falling thus causing 

equipment damage and severe bodily harm even death!

When performing trailer inspection and maintenance 

activities, you must jack up the trailer using jacks and 

jackstands.
When jacking and using jackstands, place them so 

as to clear wiring, brake lines, and suspension parts 

(i.e., springs, torsion bars). Place jacks and jackstands 

inside of the perimeter strip on the supporting structure 

to which the axles are attached.

The leaf suspension springs and associated components 

(Figure 68) should be visually inspected every 6,000 miles 

for signs of excessive wear, elongation of bolt holes, and 

loosening of fasteners. Replace all damaged parts 

(suspension) immediately.

Improper weld repair will lead to early failure of the 

trailer structure and can cause serious injury or death.
dO NOT repair cracked or broken welds unless you 

have a certified welder perform the repair. If not, have 

the welds repaired by your dealer.

If the trailer is involved in an accident, have it inspected 

immediately by qualified personnel. In addition, the 

trailer should be inspected annually for signs of wear 

or deformations.
