    Getting noise from rear. Had the oil changed today and had the noise diagnosed. Turns out ill need a right side rear hub bearing assembly. $700 dollars to get it done at Mavis. I just bought the part on line for $189. Am I in for a headache? Im a Jack of all trades master of none. Dose anyone know what tools I will need? Anyone with some tech help? Thanks

    Wheel Bearing and Wheel Hub
    Removal and Installation

    1. If equipped, turn the air suspension switch to the OFF position.

    2. Remove the wheel.

    3. NOTE: Have an assistant press the brake pedal to keep the axle from rotating.

    -Remove and discard the rear axle wheel hub retainer and the washer.

    4. Using a suitable hub puller, separate the outboard CV joint from the wheel hub.

    5. CAUTION: Do not allow the caliper to hang from the brake hose or damage to the hose can result.

    - Remove the bolts, and position the caliper, pads and anchor plate aside.

    6. Remove the brake disc.

    It looks like the rear hub. For the front hub, it depends on if you have 4x4 or not.

    Looks like this is what I'm going to have to do. Any thoughts on which one to buy? The prices seem to be all over the board. Anywhere from $129 to $345. Have you guys bought one? Who from and what do you think?

    Thanks in advance
    Ryan

    It doesn't look like the hubs are greasable, Is that correct?

    What you will need:
    18mm 1/2 drive socket and wrench.
    36mm 1/2 deep dish axle socket and breaker bar.
    Mechanics wire.
    Long thin blade screwdriver.
    Loctite thread locker.

    1. Loosen the 36mm axle nut before raising the rear tire.

    2. Remove the two 18mm caliper bracket bolts and tie the caliper assembly to the spring.

    3. Remove the four 18mm bearing hub retainer bolts.

    4. Try to pull the bearing hub assembly toward you in a side to side motion. When you get clearance, remove the 10mm bolt that retains the speed sensor. If your new assembly includes a new sensor you can simply cut the wire.

    If the hub assembly won't move you can tap the spline gently with a rubber mallet. If you need additional leverage try putting the wheel back on and use it for leverage.

    5. Clean and grease the spline and bore area.

    6. Seat the new assembly on the spline and carefully run the sensor wire through the backing plate. As the assembly comes close to position seat the wire grommet.

    7. Reinsert and hand tighten the four 18mm hub retainer bolts. Don't forget to use Loctite on the tips. Tighten them to 130 foot pounds (The manual calls out two different numbers so I used something in between.) I used an x pattern and three passes to get to 130.

    8. Thread and hand tighten (with socket wrench) the 36mm axle nut. Again, use Loctite.

    9. Reattach the two 18mm caliper bolts (Loctite on tips) Tighten to 140 foot pounds.

    10. Route sensor wire attach to all anchors, etc.
    11. Mount wheel and tighten nuts to 150 foot pounds.
    12. With car on the ground tighten 36mm axle nut to 221 foot pounds.
    13. Remember to test brakes before moving.

    Job is not much more difficult as replacing the fronts. Depending on your pace, it can take about 45min to two hours per side.

    Good luck!
