    Easy Fix

    I replaced the right front yesterday and it took less than an hour. After doing it one time it will probably take less than 30 minutes.

    1. removed the 32mm hub nut while the car was still on the ground (note: purchased 32mm impact socket with life time warranty at harbor freight for $4.99).

    2. removed brake caliper & rotor.

    Initially I thought I wouldn't be able to access the two bolts on top with further disassembly. However, turning the the wheel all the way to the right and then left for the other side gives enough room to access all bolts with just an extenstion and socket-did not have to use a u-joint.

    3. Before placing the new hub in the correct position I found it easiest to put the two top bolts back in and screwed them in by hand as I guided the new hub in place.

    4. Put the hub nut back on and torqued to 134 ft/lbs. I see no issue in reusing the old nut as long as you take care in removing it.

    5. resassembled everything and torqued the hub bolt a second time after the car was on the ground.

    Drove the car and no more noise!

    Remove the drive axle from the hub and then you'll have plenty of access.

    Hopefully I can disconnect the drive shaft without taking too much else apart?

    You'll probably have to remove the steering tie rod from the knuckle if it won't pull out of the hub all the way. That's not a big deal. You'll also have to remove the strut from the knuckle and then the knuckle will be able to swing out of the way. Then, the only thing holding the knuckle anymore is the outer ball joint. Lots of freedom for movement now.

    Soak the tie rod nut with pb blaster for a while, blast the nut off with an impact, and use a big hammer to bang on the knuckle where the tie rod end passes through. This is what I did to mine when I needed to drop my front sub-frame.

    If you don't have an impact I am a fan of the "Polish impact." Put the closed end of a wrench over the nut/bolt you're working on and use a big hammer to bang on the other end of the wrench.

    A gear puller can help push the axle out of the hub if it's stuck. When reinserting, coat the splines (but not the axle nut threads) with anti-seize. Replace the axle nut and remember to stake it to the axle.
