Why the center bolt may be out (from a lippert manual):
REMOVING CENTER BOLT ON 3,000-6,000LB EQUAFLEX UNITS TOFACILITATE USE WITH TWO-HOLE FRAME HANGERS</span>
The upper bolt prevents mounting the Equaflex suspension unit in the top hole of two-hole
To lower the trailer frame height, LCI has tested and concluded the upper bolt can be
removed without detriment to the function or durability of the unit. With the trailer supported on
jack stands, use a 13/16" socket and wrench to remove the upper bolt, nut, and washers. Once
removed, the Equaflex unit can be reinstalled into the upper hanger hole if desired to lower the
frame height of the unit.
To decrease the unit further, the shackle links can be changed out and longer ones installed.
The longer shackle will decrease frame height an additional 3/8". Order Kit PN 146294 for
a tandem axle application. Old shackle links measure 2.25" from hole center to hole center, new
ones measure 3.125".
I installed the wet bolt kit too - checked the equaflex when I serviced the bearings/brakes - no issues so far.
A person posted pictures of his equaflex failure - did yours fail in the same fashion?
