2003 Toyota MR2 Spyder Parts Questions & Experts Answers

• Q: How to service and repair the wheel hub on 2003 Toyota MR2 Spyder?

  A: Service and repair operations on the wheel hub start by unwheeling and torqueing at 103 Nm (1,050 kgf-cm, 76 ft. lbs.). The next step is to remove the brake caliper and disc by detaching its 2 bolts which require a torque of 109 Nm (1,112 kgf-cm, 80 ft. lbs.) while securely supporting the brake caliper. A dial indicator shows the axle hub replacement is necessary when either measurement meets these specifications: the maximum backlash should not exceed 0.05 mm (0.0020 inch), and the maximum deviation at the surface of the axle hub outside the hub bolt should not exceed 0.07 mm (0.0028 inch). Begin the procedure by first removing the ABS speed sensor connector and afterward detach the front axle hub by unfastening the 4 bolts which require a torque of 56 Nm (571 kgf-cm, 41 ft. lbs.). Loosen the 2 shock absorber lower-side nuts to 140 Nm (1,430 kgf-cm) torque while keeping the bolts and nuts installed. The process to detach the lower suspension arm involves first removing its nut while stabilizing the suspension afterward using torques of 98 Nm (1,000 kgf-cm, 72 ft. lbs.) and secondly tightening the nut extra if new cotter pin holes do not align beyond 60°. Use Special Service Tool: 09620-62011 to perform suspension arm lower disconnect operations. The procedure to detach the tie rod end starts by removing its cotter pin and nut with a torque of 49 Nm (500 kgf-cm) and 36 ft. lbs. and extends to additional tightening of the nut beyond 60 degrees if the holes are misaligned during installation while utilizing Special Service Tool: 09610-20012. To complete the task remove the steering knuckle by first applying engine oil to the nuts' threads during installation and then take out the 2 bolts and 2 nuts from the shock absorber's lower side. The correct procedure for installation includes performing steps in the opposite order of disassembly; eventually, verify that the ABS speed sensor signals function properly along with proper front wheel alignment.
