I have a growling noise coming from the front, passenger side of my 2006 Malibu Maxx SS (49K miles). I am pretty sure it is the wheel bearing. I would like to replace it. I am looking for two things:

1. According to websites, different years use either a 34 or 36mm socket to remove the Axle Nut. Does anyone know which one for sure?
2. I have also seen varying torque values for tightening this Axle Nut. Does anyone know what torque value to tighten it to?

Thanx in advance!

Front Wheel Bearing and Hub Replacement
Tools Required
J 42129 Wheel Hub Removal

Removal Procedure
Raise the vehicle. Refer to Lifting and Jacking the Vehicle .
Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .



Remove the wheel drive shaft nut.
Remove the brake rotor. Refer to Front Brake Rotor Replacement .
Disconnect the electrical connector from the wheel speed sensor, if equipped with ABS.
Remove the wheel speed sensor connector from the bracket by depressing the locking tabs, if equipped with ABS.



Notice: Avoid tool contact to the outer constant velocity boot seal when removing the wheel bearing mounting bolts. Failure to observe this notice may result in damage to the CV boot.

Remove the 3 hub and bearing assembly bolts.
Install the J 42129 to the hub and bearing assembly in order to remove the hub and bearing assembly from the wheel drive shaft.



Remove the hub and bearing assembly from the steering knuckle.
Installation Procedure




Install the hub and bearing assembly to the steering knuckle.



Notice: This is a self-retaining fastener joint that does not require thread locking compounds. Do not attempt to clean the threads with a standard tap. If a standard tap is used, damage to the joint threads will occur.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Install the 3 hub and bearing assembly bolts.
Tighten
Tighten the hub and bearing assembly bolts to 115 N·m (85 lb ft).

Install the wheel speed sensor connector into the bracket until the locking tabs click into place, if equipped with ABS.
Connect the electrical connector to the wheel speed sensor, if equipped with ABS.



Install the axle nut to the wheel drive shaft, hand tighten the wheel drive shaft nut.
Install the brake rotor. Refer to Front Brake Rotor Replacement .



Install the wheel drive shaft nut to the wheel drive shaft.
Use a screw driver or similar tool to stop the rotation of the brake rotor.
Tighten
Tighten the wheel drive shaft nut to 215 N·m (159 lb ft).

Install the tire and wheel assemblies. Refer to Tire and Wheel Removal and Installation .

36 mm nut, and then use a air hammer with a punch head bit to drive the axle out of the hub. dont hit the threads on the axle shaft.

and then you can sledge hammer the hub out of the knuckle, or you can air hammer it out.

disconnect your abs connector if equipped.

should take bout 20-30 minutes to do it.

Depending on what tools you have available to you, you will have a few different options. The J42129 is for removing the drive shaft from the hub, but heavilly siezed shafts can be tough. as a service technician myself, I would also definately recommend the airhammer method as the safest/easiest. as for the hub, if you're getting rid of the hub anyways, you can beat the backside of the flange with a hammer. you can attempt to thread the hub mounting bolts in a few turns and use them to beat on if you're carefull. If all else fails, you can use a chisel in between the hub and knuckle mounting surface, and try to wedge them apart. I have had luck with the last strategy on the most stubbornly siezed, but you must be careful not to mess up the mounting surface too much. if you score it, it is important that you sand the edges down flat again so that you don't create runout at the flange. good luck.

Thank you renseven for the reply. I successfully removed old hub, spend lots of time on it, and only chiseling method helped, then I used J42129 do depress axle from the hub. I've polished surface to make sure it even and smooth, also I straighten the dust shield I got bend a bit during chiseling process.... works ok so far!
