Rear wheel bearings- Dodge Shadow

My son asked me to help replace the bearing in his Shadow, and I'm looking for any input before I head up there. Any Help? Thanks.

They are tapered roller bearings. You'll need grease, seals, new races that hopefully came with the bearings, and cotter pins. No big deal.

If the new bearings aren't installed properly, they can fail in short order. Once properly greased, it is critical to seat the bearings and to set the proper axial clearance. Below are instructions to install a new bearing.

When pressing a new outer race into the hub, be ever-so-careful not to apply force across the rolling elements, This'll damage the races and cause the bearing to fail in short order. Force can only be used on the side of the outer race.

When regreasing, pack the taper roller by placing a dollop of grease in the palm of one hand, and scraping it into the spaces between the rollers until full. Butter all the hub interior cavity surfaces with grease. Place both inner and outer raceway into the hub and add grease to the sides. Install grease seal.

Make sure you use a quality grease, typically a lithium-based NLGI 2 grease with EP additives for high temperature applications. Don't go too happy with the grease, since too much will reduce thermal transfer properties, thus reducing life of the grease and bearing.

Once everything is assembled back on the spindle, rotate the hub while wrenching down on the hub nut. This'll seat the components and squeeze the excess grease from the bearing running surfaces. Wrench down until it's difficult to turn the hub. Then back off the hub nut until slack.

Set the hub nut for proper axial play according to specifications. It's best to use a dial gauge for this. If you go by feel, as most of us do, tighten the hub nut finger-tight, then back off until slack, and install the cotter pin.
