1985 SOMERSET REGAL
Some early built 1985 Somerset Regals exhibit a sharp cracking noise from the rear of car when driving over moderate to severe bumps. This condition
may result from low torque on the retaining bolt and nut which attaches the rear axle to the underbody. To repair this condition, tighten to 80-95 N-m
(59-70 ft..lbs.).
AXLE RETAINING BOLT
The torque is to be applied to the washer side of the axle retaining bolt. See Figure. If the washer is on the nut side, use torque wrench on the nut. If the
washer is on the bolt head side, use the torque wrench on the bolt head. After VIN FM405885, the axle retaining bolt washer was moved from the bolt
head side to the nut side.
