I took a look at the front passenger wheel on my 2004 W22 chassis Newmar Kountry Star and noticed that the gear oil from the front hub had leaked out.

I am going to replace the axle seals and bearings.

Does anyone have the parts needed for this job listed. My local Truck parts store can supply the bearings and seals, but I will need to get them part numbers.

UltraRV.com has all the parts.

You could also pull a hub, then pull the seals and bearing and take them to the parts house.

I'm curious why you are changing the wheel bearings. Presuming your wet bearing cups have never been dry the bearings should last a LONG time.

What is leaking? Is it a bearing seal or the gasket for the wet bearing cap? Either way changing the seals should be enough.

I had a leak and it was the Wet Bearing Hub cap Gasket. The seals were fine. Maybe that is all that is wrong with yours!?

If you insist on changing the bearings UltraRV.com has the parts. Click this LINK. At the bottom of the web page is a scroll that lists all the parts for the hub assembly. It includes the bearings, the seals, the races (I think), wet bearing hub cap, etc.

You may also want to watch Kevin’s video on changing those seals. It’s very informative. The front seal is about half way through.

Kevin is a fantastic resource for all things Workhorse! I spoke to him last week and have the list of parts he got for the brake job on his video. He had 4 different bearings listed, two for the front hubs and 2 for the rear. He didn't remember which ones went where, although I may be able to see if I can figure out the part numbers from his brake video.

Brazels does indeed have nearly everything for our rigs, and I have purchased several thousand dollars worth of parts from them in the past 4 years. Cross-referencing is difficult through the part numbers, so pricing can be, um, out of whack. The same can be said for nearly any Auto / Truck dealer, but I shop around for those items when possible, too.

For example, I bought inner hub seals in June 2021 as part of a front brake job, $45 then, and quoted $105 today. FleetPride has the same Stemco Seal (308-0866) for $75. So, yeah, it's gone up, but 50% more for the same part at FleetPride is a big premium.

Similarly, Brazel's inner and outer bearings are $72 and $155, while FleetPride has the same Timken bearings for around $40 and $72.

If Brazels (or Ford, Chevy and Honda dealers) came relatively close to other options, I wouldn't hesitate to buy everything from them.

I noticed the oil had leaked out of the inner hub seal (outer hub seal was fine) when I changed the engine oil last week. My wife and I took our 05 Newmar Kountry Star (04 W22 Workhorse Chassis) from our home in Charleston SC to Glacier NP in September. I checked the hub oil levels a couple of times during the trip, so it is possible that the oil in the hub leaked out after our return, but more likely that it had been going dry over the course of 1000 miles or so.

I was probably hearing wheel bearing droning noise the last couple of days of driving, but this dummy had getting home on his mind and didn't connect the dots in time.

Thanks,

Tom

If you ran with a bearing cup dry you probably damaged the bearings on that side.

If that is the case I would change the bearings, races, seals and wet bearing hub cap gasket. All those parts are available from UltraRV.com. If you can find the part numbers they may be less expensive somewhere else.

I did a brake job on the front of my W20 (exact same brakes as W22). I did not install new seals nor did I install new wet bearing hub cap gaskets. The right side leaked from the wet bearing hub cap gasket. I did not run it when dry so I did not damage my bearings.
