Kevin,
In case you haven't found out yet, to answer your question: the bearing kit from Jim K is for one front wheel, it includes Timken USA bearings, races, and inside and outside double seals. It is expensive but you will get the best and correct parts. Jim also has the kits for the rear wheels, again Timken USA bearings. Front and rear bearings have different part numbers.
This past summer, I replaced all of the bearings and seals on the rear wheels, in addition to replacing the entire brake system to include stainless steel lines, booster, etc, etc.
This past fall I took my coach to Chuck Boyd's Garagemahall and let him do the bearing replacement on the front wheels. He has the tools and especially the expertise to do the job. I helped the best I could. I haven't driven my coach much because of not knowing the condition of all of the wheel bearings, plus I had to fight the steering to keep it out of the ditch. After removing the front wheels , Chuck found the cv axle nuts were actually only finger tight, a wrench was not needed to remove them. The seals had hardened and broken apart, the bearings had traces of metal filings in the grease (two colors of grease), one hub was out of specs and had to be replaced with a spare Chuck had. After a good cleaning, Chuck drilled and installed grease zerks on both knuckles. Everything was cleaned ,greased and put back together with the proper torque on the axle nuts. As always with Chuck, after finding those problems, he checked the alignment of the steering box, it was 90 degrees out. After we got that straight, he drilled and installed a grease zerk on the top steering u joint, then on to aligning the toe on the front wheels. Also somewhere in the past a PO had installed a large heavy duty steering damper on the coach. It had leaked and was shot, I removed that beast as I was actually fighting it to turn to the right. I'm glad I live close to Chuck.
The PO I had bought the coach from had taken it to two garages to have work done on the front suspension , one had been a GMC motorhome shop and the other was a heavy truck repair shop. One of them had neglected to torque the cv axle nuts and it could have been disastrous.
So, follow the advice of the fellow GMCers and I would also recommend getting expert help on the front end.
Cheers,
Jerry
