Here is a great set of instructions for the installation of a front wheel hub bearing assembly. One of our customers submitted this for us to show to the public. Hopefully anyone thinking about tackling this job will find these helpful. Also please rate our guide at the bottom of this page.

These instructions will work for numerous GM front wheel drive vehicles, these came specifically from a 2002 Buick Lesabre Limited:

2002 Buick Lesabre Limited

1. Remove hub dust cover by prying off with screwdriver.

2. Jack up vehicle and support properly .

3. Remove lug nuts using 19mm socket. Remove wheel and set aside.

4. Remove 2 caliper mounting bolts using a 15mm socket. Set caliper aside. Do not let it hang from rubber brake hose.

5. Remove 2 caliper mount bolts using 15mm socket Set caliper mount aside.

6. Remove brake rotor and set aside.

7. Remove 3 hub mounting bolts using 13mm socket.

8. Remove axle nut using 1 5/16" or 34mm socket.

9. Unhook sensor plug.

10. Remove hub assembly. It may require a hammer or very rarely a puller to get the hub loose. Hit the hub and pry with a screwdriver until hub comes out. (Most Auto Zone or Advance Auto Parts stores will allow you to borrow a puller if needed.)

11. Clean mounting area with a wire brush so new hub slides in easily. Apply anti seize compound if desired.

12. Install new hub assembly.

13. Use thread locker on the 3, 13mm mounting bolts and tighten.

14. Hook up the new sensor plug.

15. Install the axle nut using a 1 5/16" or 34mm socket. VERY IMPORTANT!!! Do not over torque or under torque this nut. Also it is strongly recommended to never use an impact wrench to tighten this nut. Please tighten with a torque wrench to 118 ft. Lbs.(Other year and model vehicle torques specs may differ, please email us if you would like to know yours. Over or under torqueing this nut is the number one cause of premature bearing failure!!!!!!( It is also recommended to replace this nut as the threads will usually be stretched from being installed and removed. Threads will definalty be stretched if installed with an impact wrench.

16. Install the brake rotor.

17. Use thread locker on the 2, 15mm caliper mount bolts and tighten.

18. Install the caliper mount bolts using a 15mm socket.

19. Install the wheel using a 19mm socket (Torque lug nuts with torque wrench to 100 Ft. Lbs.) and press hub dust cover into place.
