AXLE - FRONT DRIVE - DAMAGED LEFT HAND ARM - 4x4 VEHICLES
LIGHT TRUCKS 1980-82 BRONCO, F150-350
Severe applications of 4x4 vehicles (e.g., snow plowing) can result in damage to the left axle arm between the spring seat and the carrier housing.
Revising the two axle arm "Tab" to housing bolts from 3/8" to 1/2" will strengthen the arm and update the connection between the housing and the left
axle arm to latest level.
When resolving a concern involving a damaged left axle arm between the spring seat and the carrier housing, the following procedure should be
followed. In addition, if either the arm or the carrier is replaced, they should be reworked as described, to assure compatibility of the bolt holes.
-
Inspect the left hand axle arm tab bolt holes. Ream 7/16" diameter (slotted) holes (2) to 9/16" diameter round holes if necessary.
-
Inspect carrier housing. Ream the two axle arm to carrier housing attaching bolt holes, if the tapped holes are 3/8" diameter. Re-tap the holes (2) to
1/2" - 13 UNC-2B thread.
-
Attach axle arm to carrier housing using part number 621032 - 1/2" diameter bolts supplied with axle arms. Torque the 1/2" bolts to 82-115 ft.lbs.
