wheel bearings

First a comment on RV Professionals, I have not found one yet, ok that is my rant.

It depends on the type of wheel bearing.

The below is from another post of mine.

If you do not have an oil bath bearing or a hub bearing you many find this useful.

I saved all my tools, learned the lesson never sell a tool as you get nothing for them and as soon as you sell one you need it. This is a bearing packer and does a great job. The bearings are the ones from the trailer (seals said dexter on them, bearings are from china).



This is a photo of the bearing in the packer, I am using red grease, brand can be seen in the previous photo. Note that it came out right away (leading edge white, indicating very little of the grease that was used to pack the bearings a CW)





Now these bearings are PACKED with grease, excess can be wiped away.



So.... now back together we go.... a little grease on the spindle.



Seal seated correctly.



Correct preload on the bearings and spindle nut retainer in place. To get the correct preload tighten the spindle nut while turning the drum. when the spindle nut meets resistance, stops turning with a small amount of effort (a light touch is needed), back the nut off one flat (just far enough that you can get the cotter pin through one of the openings in the castle nut retainer.

If you do not under stand this get help.

As for the perceived high cost of professional repair. Keep in mind that Class A RV's consume a LOT of 'floor space' and mechanics that are qualified to work on them are truck mechanics. As someone pointed out, the average person really shouldn't even be pulling wheels off these big boys. I've been a mechanic all my life but yield to the pros to do the heavy chassis work on my Fleetwood. That said, you can still do a lot (fluid changes, minor mechanical repairs) and save a lot of money. The big 'rolling hardware' work isn't the domain of the DIY person, though. Our previous Class C was MUCH easier to work on and I did more on it. My experience is the chassis repair can be handled by truck stop repair shops. You get stuck at the 'end of the line' (guys making a living driving come first AND you have a rolling house to wait your turn in) but those places have the best mechanics and don't charge anymore than the not-so-pros at the RV dealer.

Please post what make model and year of the chassis.
Still, this is either medium duty truck or bus stuff, and will be a whole lot different than repacking the timkins in my old Camaro.

Also, at least here, cummins care does not deal with chassis issues.

If you have a diesel pusher, would head to a Cummins Care center, I do not trust the run of the mill RV shops, keep having nightmares about the CW bad happenings you keep reading about.

Anyone that has read the various posts on this forum knows that finding the PROFESSIONAL to do work on your coach is very difficult. If you have an XYZ coach, and you pull in to an RV service center, they will assign a "mechanic" to work on your coach, charge you a huge amount for labor, even if this is the first time this center has ever seen an XYZ type coach.
The work may or may not be done correctly, but you will still get the bill. There have been many many posts about unsatisfactory work being done with some exorbitant labor charges. Basically you may end up paying for some low level wrench turner to get a little "on the job" training.
You best bet is to either research what needs to be done to adjust your wheel bearings, decide if you are capable to do the work, or find a truck service center that will work on your specific type of chassis. The research is important so that you can get some idea as to whether or not the service center is BSing you or if they actually do know what they are doing.

If you think you remove the hub to get the bearings out to tighten them up, PLEASE get a professional to do the job for you!

Sorry, but if you have to ask how to do it then perhaps you shouldn't be doing it. Since you posted this in the Class A motorhome section, I'm assuming that's what you have and I really don't think you should be messing with even removing the tire.

Do you have any mechanical skills/ability?
Ever done wheel bearing job before?

NO........pay to have it done.

If you still want to attempt it on your own.......post which vehicle you have. Brand/model/chassis etc.
Otherwise it's all a guess.

IMHO...if you don't know what you're doing, pay a professional to do it. That said, learn from them while they're doing it. The next time you'll be able to do it. A professional may see something else that's wrong too.......my opinion....Dennis
