Ball Joint Checking

  1. Raise front of vehicle and support with stands. Check ball joint for grease leakage, and dust cover for cracks or damage. Check ball joint end play.
  2. Attach dial indicator to transverse link with indicator tip against lower edge of brake caliper. Ensure front wheels are in straight-ahead position. Place a pry bar between transverse link and wheel.
  3. With brake pedal depressed, raise and release pry bar. Observe dial indicator. There should be zero vertical end play. If reading exceeds specification, remove transverse link to recheck.
  4. Place transverse link and ball joint assembly in a vise. Rotate ball joint at least 10 revolutions prior to checking with pull scale. This will ensure ball joint is properly seated.
  5. Attach a pull scale at cotter pin hole of ball stud and check torque. See Fig 1 . Reading should be 1.8-17.4 lbs. (.8-7.9 kg). If reading is not within specification, replace transverse link. Ball joint cannot be replaced separately.
  6. Install ball joint stud nut. Using an INCH-lb. torque wrench, measure amount of torque required to turn ball joint stud. See Fig 1 . Reading should be 4.4-43.4 INCH lbs. (.49-4.88 N.m). If reading is not within specification, replace transverse link. Ball joint cannot be replaced separately.
