I'm looking for a response from someone who has done a front rotor and pad replacement other than the workhorse recall.My son-in-law has a 2003 W22 chassis. The recall was done a few years back. They replaced the calipers but would not replace the rotors even though the had small cracks on the whole surface of the rotor.He purchased some new rotors and pads that are after market and much better than the stock units. I don't have the brand name offhand.There are RV shops here in So. Cal. who will provide the labor to replace them but I'm amazed how ignorant some of these so called techs are. One shop told him he didn't know what he was talking about when he asked if they had the proper equipment to torque the lug nuts to 475 ft.lbs. They said the torque was not that high. Spec on the W22 with 22.5 wheels is 450-500.Another shop said they would also repack the wheel bearings along with replacing the rotors and pads. Well the W22 has oil bath lubrication on the front hubs, not greased bearings.We have thought of doing it ourselves, but getting the right torque on the lug nuts is a concern. I assume the rotors slide off once the wheel and caliper are removed, can someone confirm this?I did contact a shop in Chino that seems knowledgeable (McBrides),and he may go that route. The labor quoted was $300-$400. That doesn't sound to bad.My point is beware of some shops who claim to know their stuff. These statements I gave from them were from well known dealers in the area.

Forget the RV shops. Take it to any one of the many Workhorse authorized service centers.There are 34 in Cal.,or GM truck service center.

You are right, the lug nut torque is 475 FtPounds. I have no problem taking my lug nuts off using a 3/4" breaker bar, with a 12" socket extension, and a 4' pipe for leverage. I use an adjustable jack stand to hold the breaker bar in place, and then I can put all of my weight on the pipe extension to break the lugs loose. Even stand on it if I have to. On the plastic hub cover, if you rotate the wheel properly to put the drain on the bottom, you can remove the plug and drain the lubricant. Order new rear seals for the hub and replace them while you have the assembly off of the vehicle. Then it is basically a take things apart and reverse the procedure to put things back together. I also changed my front brake lines at the same time since it was a lot easier when everything was apart. After all, the hoses on his rig are now 11+ years old and you have to bleed the system anyway. Probably a good idea to flush the entire brake system which will take 3 quarts of brake fluid. If you have a 3/4" socket and breaker bar, this is something you can do yourself as long as you realize that everything is heavy and it is easy to pinch a finger or two. The rotors and the wheel assembly are heavy.

The Workhorse shop in Grand Junction CO that did my recall did not have any way to set the torque properly. They agreed to use my my 3 to 1 torque multiplier and 250 ft pound torque wrench though. However I set up an appointment for that same afternoon at a tire shop a few blocks down the street to replace all of my tires so I let the WH shop just use their air wrench and the tire guys used my tools instead.

You have two good truck/RV shops in your area, Redlands Truck Center and Colton Truck Center. Both get good ratings from users. Lastly, calling a shop and quizzing them is really not fair unless they see the vehicle. Not every W22 chassis came with oil bath hubs. How were they to know? Second, most shops are not going to get out a torque wrench and torque your lug nuts (just a reality). They use a one 1" impact to put on and take off.

Use 24" long breaker bar and stand on the end of it. 220 lbs @ 24" = 440ft/lbs.

It does mean they don't know if the lug nuts are properly torqued or not. That may not be important to some but it is to me.

I don't know if all Walmart stores do it but our local Walmart sets the torque with a torque stick/air wrench and then the vehicle is driven around the block/lot and a different guy checks it with a torque wrench and initials that it is okay.

Most truck centers I have been to never use a torque wrench on the wheels!! Does not mean they don't know what they are doing.

I believe he will take it in to Mc Brides who is a authorized Workhorse service center. In reply to DSDP Don, if I explain to a shop what chassis I have and what I want done, they shouldn't make statements that show their ignorance if they are not up to speed on that type of chassis. Maybe that was a good thing as it eliminated that shop from doing the work that we needed done.
If I know the basics of the W22 and they do not, that's a red flag to me. Any competent shop who does work on these large chassis should know the importance of correct lug nut torque. Especially on the front wheels.
If I'm paying good money for a service, I would expect the work to be done professionally and by knowledgeable mechanics. Again, my point is beware of where you take your coach for any work you need done. Wireman

:pAll Workhorse W22 have wet hubs (oil bath)

The hubs have to come off to remove the rotors. The hubs are heavy try not to damage the new oil seals when you put the hub back on. Also, do you know how to pre-load the tapered roller bearings? Good luck if you choose to do it your self.

What years did the W22 not have wet hubs as standard equipment?
