•
Check condition of wheels and rims.
Especially look for cracks, missing
lockrings, bent or broken spacers,
studs, clamps or lugs.
•
Check condition of tires: properly in-
flated, no serious cuts, bulges, tread
wear or any signs of misalignment;
valve stems not touching wheels, rims
or brake drums; valve caps in place
and no objects stuck between the
wheels.
•
Check that both tires are of same type,
for example, not mixed radial and bias
type and that their circumferences are
matched.
•
Check wheel bearing and hub: no obvi-
ous leaking on outside or inside wheel.
Suspension
•
Condition of springs (leaf or air),
spring hangers, shackles and U-bolts.
•
Axle alignment.

Condition of torque rod arms.
•
If equipped with sliding axles, check
position and alignment. Look for dam-
aged, worn or missing parts, all locks
present, fully in place and locked.
•
Flexible air tubing not cracked, cut,
crimped or otherwise damaged. Se-
cured against tangling, dragging and
chafing.
Brakes

Condition of brake drums. With brakes
released, look for a noticeable gap be-
tween lining and drum (This check
cannot be made if dust covers are in
place).

Condition of brake hoses: check for
any chafing.

Check brake chamber mounting bolts
and brackets.
