NOTE
Some fraying of a new ultra bushing may occur
as a new bushing wears in. Minor fraying of
the urethane part of the bushing protruding
beyond the axle housing over the trunnion cap
is common and should be removed when found.
On all 10 suspension assemblies, check ultra bushing
(8) for signs of deterioration and fraying of urethane
part of bushing. If urethane portions of ultra
bushing (8) are frayed, straighten two corners of each
lock plate (9). Remove four capscrews (10), two lock
plates (9), and trunnion cap (11). Using a knife,
trim all frayed strands off of ultra bushing (8). If
a gap of 1/8 inch or more exists between urethane and
either metal shell at top of ultra bushing (8), notify
DS maintenance. After trimming is complete, install
trunnion cap (11) and secure with two lock plates (9)
and four capscrews (10). Using a torque wrench (item
17, appx. B), torque capscrews (10) to 100-110 lb-ft
(136-149 Nm). Bend one corner at each end of lock
plate (9) against a flat side of capscrew (10) to
secure each capscrew.
