2003 Toyota Tundra Parts Questions & Experts Answers

• Q: How to service and repair the wheel hub on 2003 Toyota Tundra?

  A: Start hub wheel service by first using screwdriver and hammer to remove the front wheel alongside its grease cap. The drive shaft disconnection process for 4WD models includes removing the cotter pin and lock cap prior to taking out the lock nut while holding the brakes engaged. Operators must disconnect both ABS speed sensor and wire harness clamp from the steering knuckle through the removal of two bolts. First disconnect the brake caliper along with disc by removing the steel bolt and brake tube clamp from the steering knuckle before removing the two brake caliper and disc bolts while ensuring to not damage the brake tubular and securely supporting the caliper. Start by taking off the shock absorber before proceeding to disconnect the lower ball joint through removal of the 4 essential bolts. Before extracting the steering knuckle engineers should remove its cotter pin and nut before disconnecting it using Special Service Tool: 09950-40011 (09951-04010, 09952-04010, 09553-04020, 09554-04010, 09955-04031, 09958-04011). Installation requires similar steps in reverse order. First secure the drive shaft within the axle hub while loosely tightening the nut to maintain the oil seal condition before linking the steering knuckle to the upper suspension arm then fasten the new cotter pin and further tighten it up to 60 degrees if the pin holes are not aligned, and apply torque of 105 Nm (1,100 kgf-cm, 77 ft. lbs.). Connect the steering knuckle to its lower ball joint with four bolts that need 80 Nm of torque (820 kgf-cm or 59 ft. lbs.). After that, install the shock absorber. To install the brake caliper, first place the disc and caliper before securing the two bolts with 123 Nm (1,250 kgf-cm, 90 ft. lbs.) torque. The brake line clamp should be attached to the steering knuckle through a 28 Nm (285 kgf-cm, 21 ft. lbs.) torqued bolt. The ABS speed sensor and wire harness clamp must be connected to the steering knuckle using 2 bolts that should be tightened to 8.0 Nm (82 kgf-cm, 71 ft. lbs.). The drive shaft lock nut installation requires braking of the vehicle while the torque reaches 235 Nm (2,400 kgf-cm, 173 ft. lbs.) followed by cap installation along with a new cotter pin that should be tightened up to 60° if possible. To complete the task, first install the grease cap before torquing the front wheel to 110 Nm (1,150 kgf-cm, 83 ft. lbs.) and depress the brake pedal multiple times and inspect the front wheel alignment and ensure the ABS speed sensor signal is intact.
