Disc RUNOUT

WARNING: This page is about a different car, the 2004 Toyota 4Runner and 2003 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove front wheel.
  2. Remove caliper support assembly and suspend aside.
  3. Install and tighten 3 hub nuts to specification. See TORQUE SPECIFICATIONS .
  4. Using a dial indicator, measure disc runout. See Fig 1.
  5. Make a note of runout and compare to specification. See DISC BRAKE SPECIFICATIONS .
  6. If disc runout is maximum value or greater, check the bearing play in the axial direction and check the axle hub runout. Maximum runout should not exceed .002 in. (.05 mm). If the bearing play and axle hub runout are normal, go to next step.
  7. If minimum runout recorded is greater than specification, replace disc. It is possible to adjust disc runout by grinding it with an "on-car" brake lathe.
  8. After repairs, install torque plate and tighten 2 bolts to specification. See TORQUE SPECIFICATIONS .
