If you're going to pull the axles out to do that might as well replace the bearings and seals and see what happens. They are inexpensive. I got a recommendation from someone here to get the premium NAPA brand. NAPA had their economy bearings in stock but I asked them to order the premium ones and they were at the store in a couple days. Car parts stores loan the bearing puller and slide hammer needed to do the job. When trying to remove the axles you may run into the problem of broken differential pinion shaft lock bolt. Don't let it alarm you too much, if I can replace that I bet anybody could, it does take patience.
