bolts that connect the stock front differential drop bracket
to the stock front differential. Save the stock hardware for
later re-installation. Next, remove the stock front
differential drop bracket from the stock front cross
member and save the stock hardware for later re-

Locate (2) PB2408 poly bushings and (1) S10082 crush
sleeve from hardware bag 55905SL. Install the new poly
bushings into the new driver side differential drop
bracket. Next, install the new anti crush sleeve into the
newly installed poly bushings. Special note: Make sure
to use a lithium or moly base grease prior to
inserting the new bushings into the new driver side
differential drop bracket. This will increase the life of
the bushings as well as prevent squeaking.
36. Locate the (3) stock driver side front differential bolts
that were removed in step # 32. Also, locate (3) new
9/16” flat washers from hardware bag 55905NB. With the
