For those who haven't worked on one, or doesn't know what a semi with a C-Clip
holding the axle on...here are a few pic's
Here is a typical C-Clip and the axle end with the grove for the C-Clip. The
C-Clip is inside the diff pumpkin housing

This pic is of a C-Clip that has failed and the axle is running out of the
axle tube. *ONE* bearing on these and it's outboard by the brake flange/backing
plate. Not towing, so if towing...it would have much higher loads and
stresses on the rear axle

Here is how it looks like when working on one. That is the ONLY bearing for
most semi-floaters

This is where the C-Clip and axle end resides inside the diff pumpkin housing

Taking out the C-Clip

This is the C-Clip and the axle end grove

This is a full floater

Full floater axle coming out and notice that the wheel lug studs
REMAIN attached to the axle flange/tube

This is common for us serious off roaders while in compound low...
A full floater and this axle is busted...but...it left the wheel still
bolted to the axle flange
