not worn or cracked; joints, sockets and boot
seals are not worn or loose and that there are
no loose or missing cotter keys, nuts or bolts.

leaves that are in contact, or nearly contacting
a tire, rim, brake drum, frame or body
components.

axle mounting bolts and nuts for cracks,
breaks, wear, damage, tightness and correct
component quality.
Shock absorber:Check for cracks, leaks and missing or broken
bolts or bushings.

should follow trailer manufacturer recommendation and should include at
