1	Spacer Bolt M8 x 127 (Qty: 8) NOTE: Refer to Fastener Notice . Procedure Install the remaining spacers evenly at every other bolt hole. Remove the DT 47800-6 which is part of DT-47800 , guide pins and install spacer bolts in all bolt holes at spacer locations. See Special Tools . Tighten the bolts in sequence to: Tighten: 30 N.m (22 lb ft) Special Tools: DT-47800 Thrust Washer Selection Gage Kit. See Special Tools .
2	Front Differential Carrier Assembly NOTE: If the bearings are not properly seated into the bearing cups, the washer selection will be inaccurate and the bearing pre-load will be set too low. Low bearing pre-load will cause premature failure of the front differential drive pinion gear. Rotate the differential assembly 10 revolutions to allow the bearings to seat into the cups. Tip: Differential rotating tool DT-47793 can be used to rotate the differential from the case side. See Special Tools . Special Tools: DT-47793 Differential Rotating Tool. See Special Tools .
