After another short over night trip last weekend I just had to check the wheel bearings. I worked with the mechanic next door to my workplace and he showed me how to repack the first one so that I could do the other. Upon inspection we found that the bearings were in great shape and that there was no immediate concern. I took a couple of shots while removing the first hub but was unable to do more in the shop because my hands were covered in grease. Here is a rundown of the process assuming you don't need to replace the bearings and races.
Gently pry off the dust cover.
Remove the cotter pin holding the hub nut.
Spin the nut off the spline.
Pull the hub off (the front bearing falls into your hand at that point).
Clean the grease off of the spline with a rag.
The rear bearing is inside the hub behind a grease seal that will likely be damaged on removal. I found similar (correct size) seals at NAPA (part number 16735) for $20 each.
I cleaned the inside of the hubs using the solvent wash in the mechanics shop but it can be done manually of course.
The mechanic told me not to clean the bearings but to repack them as they are instead. We used a bearing packer but one can do it by hand as well. Just force new grease into the bearing to push the old out. We used synthetic grease.
Place the rear bearing back in the hub and tap the new seal into place flush with the hub.
Slide the hub back onto the axle
Put the front bearing in place, replace the washer and nut and tighten until firm. Back off the nut until the cotter pin can be re-inserted and replace it. The hub should turn freely at this point and should not be too tight.
Replace the dust cap.
Mount the wheel.
