2.10 Pre-Season Maintenance
Before removing the trailer from the jack stands:
1. Remove all wheels and hubs (brake drums). Note which spindles the drums were
removed from so that they can be reinstalled in the same location.
2. Inspect the suspension for wear and corrosion and correct any discrepencies.
3. For leaf spring suspensions, check the tightness of all the hanger bolts, shackle
bolts, and U-bolt nuts per recommended torque values (see page 16).
4. Check all brake linings, brake drums and armature faces for excessive wear or
scoring.
5. Check brake magnets with an ohmmeter. The magnets should check at 3.2 ohms.
If shorted or excessively worn, replace the magnets.
6. Lubricate all brake moving parts.
BRAKE LINING CONTAMINATION!
Do not get grease or oil on brake linings or magnet face.
7. Remove any rust from braking surface and armature surface with fine emery
paper or crocus cloth. Protect the bearings from contamination while so doing.
8. Remove and re-pack the wheel bearings (see page 18). Install new grease seals
when the bearings are reinstalled.
9. Reinstall the hubs and adjust bearings as outlined on page 19.
10. Remount and torque the wheel lug nuts. Be sure to remember to re-torque the
lugs periodically (see page 21).
11. Check cold tire inflation pressures- ST235/80R16, 65 psi.
