  1. Tank assembly (fuel system)

    NHTSA 95V234000 Reported 876 vehicles potentially affected FREIGHTLINER CORPORATION

    Two top mounting straps secure the fuel tank to the frame. Breakage has occurred where the strap bolts to the frame rail.

    Remedy: Dealers will install a stronger strap replacing the upper strap. A frame crossmember/channel, designed to bolt onto the frame lower flanges directly behind the fuel tank, will be installed when the chassis design did…

    Model years: 1990, 1991, 1992, 1993

  2. Rack and pinion (steering)

    NHTSA 95V021000 Reported 1,057 vehicles potentially affected OSHKOSH TRUCK CORPORATION

    Metric grade 8.8 bolts were mixed in inventory with metric grade 10.9 bolts. Incorrect grade bolts (8.8) were used in attaching the 710 saginaw steering gear to the frame.

    Remedy: Dealers will replace all metric grade 8.8 bolts with the correct metric grade 10.9 bolts, loctite will be installed into the bolt hole, and the bolts will be torqued to specification.

    Model years: 1994

  3. Mounting (fuel system)

    NHTSA 94V067000 Reported 842 vehicles potentially affected OSHKOSH TRUCK CORPORATION

    An "l" shaped bracket welded to the fuel tank suffers from fatigue failure of the strap weld to the fuel tank. When one strap fails, the tank will allow the tank to move will the vehicle is in motion, causing increased fatigue to other tank attachment welds.

    Remedy: Springs at the four lower strap mount connections to the lower frame have been positioned to compensate for frame movement. These springs will provide consistent strap force around the tank regardless of frame movement.

    Model years: 1990, 1991, 1992, 1993
