2007 Toyota Tundra Parts Questions & Experts Answers

• Q: How do you service and repair the front Wheel Hub on 2007 Toyota Tundra?

  A: The first steps for front axle hub service and repair require wheel removal and subsequent detachment of the front disc brake caliper assembly LH together with removal of the front disc and front axle hub grease cap LH (exclusive to 4WD models). A dial indicator should be used to inspect front axle hub bearing looseness while it maintains a right angle to the measurement surface with a maximum looseness of 0.05 mm (0.00197 inch). A new axle hub replacement is necessary if this limit is exceeded. The axle hub outside the hub bolt surface needs runout measurement up to 0.03 mm (0.00118 inch), replacing the hub if this standard is exceeded. The procedure ends with installation of the front wheel for which you must torque it to 131 Nm (1336 kgf-cm, 97 ft. lbs.) for aluminum wheels or 209 Nm (2131 kgf-cm, 154 ft. lbs.) for steel wheels. Whenever a front axle hub grease cap LH (for 4WD) is involved, follow this same torquing method. Proceed similarly for LH side removal by starting with front wheel detachment followed by disconnection of the front disc brake caliper assembly LH that preserves flexible hose connection then taking off the front disc LH. To begin LH 4WD front axle hub work you must carefully pull off both the front axle hub grease cap LH using a screwdriver and hammer combination along with the front axle hub nut LH by unfastening the cotter pin and adjusting lock cap and nut. When servicing the front axle hub sub-assembly LH on 2WD vehicles, eliminate the 4 bolts while 4WD vehicles require the bolt removal and cautious front drive shaft extraction from the hub with a plastic-faced hammer to safeguard the boot. When disassembling the system not allow contaminants to touch the ABS rotor bearing. Use Special Service Tool: 09930-00010 with a hammer to unstake the staked part of the front wheel adjusting nut (2WD). The Special Service Tool: 09318-12010 will allow you to remove the adjusting nut (2WD). Fix the front axle hub within a vise but protect its bolt threads before removing the bearing with Special Service Tool: 09710-30021 (09710-03051) and 09950-40011 (09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04061, 09957-04010, 09958-04011). Pry out the front axle hub oil seal with a screwdriver. To reassemble the assembly install the new oil seal by striking it with a brass bar and hammer but press in the new bearing using Special Service Tool: 09649-17010. Fasten the new 2WD front wheel adjusting nut with a torque setting of 382 Nm (3895 kgf-cm, 282 ft. lbs.). The installation process requires fresh application of MP grease to an O-ring before placing it into the axle hub while avoiding any harm to the component. Next, install the dust cover and axle hub onto the steering knuckle using 4 bolts which must be torqued to 99 Nm (1010 kgf-cm, 73 ft. lbs.). When installing front drive shafts to front axle hubs on the 4WD system take care to protect the boot and follow the same procedure. When installing the front axle hub nut LH for 4WD operation the torque should be set to 338 Nm (3446 kgf-cm, 249 ft. lbs.). The installation process requires inspecting the front axle hub followed by attaching the front axle hub grease cap LH for 4WD and inserting the front disc LH. Connect the front disc brake caliper assembly LH via two bolts while applying 99 Nm (1010 kgf-cm, 73 ft. lbs.) torque but avoid twisting the flexible hose and confirm the bolts have no damages or foreign substances. After installing the front wheel it is necessary to check the speed sensor signal while performing the following steps: connect the brake tube bracket to the steering knuckle using the bolt and torque it to 29 Nm (296 kgf-cm, 21 ft. lbs.).
