procedure is erroneously referred to as "flipping the axles".
The axles are not inverted or flipped over, but are re-positioned from over to
under the springs. This will lift the trailer about 4 to 5 inches
The trailer is jacked up
and placed on jack stands. This allows the axles to hang freely
so that the work can proceed.
Proper equipment is an absolute
This is the original configuration
of the axles. The springs are mounted below the axle tubes. The
project is to raise the trailer by re-positioning the axles so
that the springs are located over the axle tubes thus raising
the trailer by 3 to 4 inches..
Wheels removed, ready to go!
Bolts removed, axle is ready to be
Axle is on the floor! The bushings
will be replaced as they are well worn. Also, all the suspension
bolts are worn and will be replaced at this time.
The new bushing is being driven
in, forcing the worn bushing out the left side.
The axle assembly is placed
on sawhorses for easier access. These nuts are rusted beyond
easy removal and the u-bolts will be cut using a cutting torch to
The stripped axle with the mounting
plate and spring removed. The axle is then flipped over to enable
the new saddles to be installed. This new saddle is ready to be welded
into place. An experienced and certified welder should be the only one to perform this operation, they know what they are doing!
This shows the spring installed
on the new saddle, the plate installed over the spring and new
u-bolts installed to hold everything in place. (Follow the manufacturers guidelines for torque specifications) Note the new bushing
being inserted in the ends of the spring.
The axle re-installed on the
trailer. The axle tube is now underneath the spring but it is
in the same relative position as it was originally.
The end result ! This trailer
has been lifted about 5 inches with this procedure and the suspension
system has had a much needed overhaul. A wheel alignment is recommended after this suspension modification.
