Installation [09/2020 - 10/2023]: Procedure
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2024 Lexus IS 500, 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 500, and 2023 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
- INSTALL WHEEL ASSEMBLY NOTE:
- If incompatible axle hub bolts are used, the spherical axle hub bolt seat of the wheel assembly may become deformed or damaged. This may result in an incorrect fastening force (axial force) leading to looseness or loss of one or more axle hub bolts, even if they are tightened to the specified torque.
*a Compatible Axle Hub Bolt Examples *b Spherical Seat Type Axle Hub Bolt *c Tapered Seat Type Axle Hub Bolt *d Flat Seat Type Axle Hub Nut *e Spherical Seat Type Wheel Assembly *f Flat Seat Type Wheel Assembly *g Tapered Seat Type Wheel Assembly *h Wheel Assembly - Check that there is no foreign matter or rust on the axle hub bolt hole threads and the contact surfaces of the wheel, brake disc, axle hub, etc. Clean the contact surfaces and axle hub bolts if necessary. If a wheel assembly is installed with foreign matter or rust between the contact surfaces, the foreign matter or rust may work loose. This may result in a reduction of the fastening force (axial force) leading to looseness or loss of one or more axle hub bolts.
- When installing the axle hub bolts, check that the axle hub bolts rotate smoothly by hand. If the axle hub bolts do not rotate smoothly, check that there is no foreign matter or rust and clean if necessary. If the axle hub bolts still do not rotate smoothly, replace the axle hub and axle hub bolts with new ones.
HINT:
Using a 17 mm impact socket wrench with cover, the axle hub bolts can be easily removed and installed without damaging the wheel assembly.
- If installing a rear wheel assembly, release the electronic parking brake.
- Rotate the tire so that one of the axle hub bolt holes (axle hub threaded part) is at the 12 o'clock position.
- Confirm that the installation bolt of the brake disc is securely tightened.
for Front Side: Refer to PROCEDURE - Step 1 [09/2020 - 11/2021] , or refer to PROCEDURE - Step 1 [11/2021 - ]
for Rear Side: Refer to PROCEDURE - Step 1 [09/2020 - 11/2021] , or refer to PROCEDURE - Step 1 [11/2021 - ]
NOTE:The mounting bolt for the brake disc must not under any circumstances protrude onto the contact surface between the brake disc and the wheel assembly.
- Install SST to the uppermost axle hub bolt hole.
- SST: 09650-53010
NOTE:Make sure that SST is securely installed.
- Install the wheel assembly using SST as a guide, and while centering the wheel assembly, install 4 axle hub bolts by hand.NOTE:
- When placing the wheel assembly on SST, make sure to position the wheel assembly within the area shown in the illustration and do not apply excessive force.
Wheel Assembly Placement Area - Make sure the wheel assembly uniformly contacts the brake disc.
- Do not apply oil or grease to the spherical seat of the axle hub bolts or wheel assembly.
HINT:
Use SST to facilitate alignment of wheel assembly with the axle hub bolt hole and to prevent the wheel assembly from falling.
- When placing the wheel assembly on SST, make sure to position the wheel assembly within the area shown in the illustration and do not apply excessive force.
- Remove SST, and install and tighten the remaining axle hub bolt by hand.
- Temporarily tighten the axle hub bolts in the order shown in the illustration.
