Front knuckle and Birfield rebuild

DIFFICULTY 3 / 5TIME ≈ Two days the first timeCOST Knuckle kit about $160 (Cruiser Corps)

Symptoms

Grease and gear oil weeping past the knuckle wiper seals, sludge inside the knuckle, or play in the front wheel.

The fix, step by step

  1. Same job as an FJ40: pull the hub, spindle and Birfield, remove the steering-arm cones and knuckle caps, then replace the inner axle seal, knuckle bearings and wiper seals.
  2. Repack and reassemble, using top shims to set knuckle-bearing preload and bottom shims to center the knuckle.
  3. Use the spec from the factory service manual.
