Wedge brakes ? Instead of S Cam type. Drum & shoes, interesting, Retarder ?

I think because the secondary and dirt enviourment the coaches were made to be used in the thought was that the wedge brakes had a full backing plate. If memory serves me s cams had open shoes.

Heard of crystallized brake drums from logging truckers getting the open drums hot then going through a water crossing repeatedly.

I am a off roader and an open drum does not seem as sealed as a backing plate setup.

What does this have to do with the wheel falling off? Probably should have started a new topic or these few posts need to be split off from this topic.

What is the mount measurments on your axle? what is the distance king pin to kingpin and any other measurments?

Does anyone know what weight axle that I need to replace the existing one? 9000lb, 10,000, 11,000 ? or what weight? The insurance estimator is looking into complete front axle replacement. He said the problem might be; the heavy duty truck axles have 10 lug and he does not know weather the 6 lug brake drum will interchange or fit the replacement axle to match my wheels.

Your GVWR sticker on the driver's wall will give you the GAWR. But, the axle model and serial should be sufficient for specs.

Well I found the identical axle complete and I can pick it up Saturday $1000, will the insurance company pay me to repair it?... rather than pay $570 to have it towed to a frame and axle shop (only 16 miles btw), and pay their labor for repair on top of that? Can the insurance give an estimate on replacing an axle labor time? The adjuster had no luck on finding the parts and I let him know I have found them. Will they give me the option of doing the repairs myself?

Re: wheel fell off

No idea what he will do, but you/he should be able to come up with a reasonable labor estimate. A call to Foretravel service department for a written estimate they can e-mail you would be a first stop.

But, if the axles are not exactly the same (wheel bolt pattern, brakes, etc) then additional labor to change components would be necessary.

The other option would be to just remove parts from the new axle to replace broken parts on your coach. But, make sure you have matching brake shoes and good "very close to same diameter" brake drums on both sides.

I agree w Brett -- ins. claim dept. should pay you the reasonably necessary cost of repair (labor and material), less deductible.
My insurer paid my earthen-berm-encounter damage according to a Michigan shop estimate to put it back as it was. I mean with Ford truck headlamps, etc.. They might not have cashed out with me if I had a lien. I put the settlement toward getting a euro headlamp conversion, in conjunction with structural repairs, at Xtreme.

You will remove the hubcap,there is a rubber plug in the middle. Remove the bolts that secure it to the hub,have a drain pan to catch the oil. There will probably be a cotter key,remove it and the nut, there probably will be a washer under the nut, Once these are off the hub will slide off the axle. The seal in the rear of the hub will need to be replaced,Take a pry bar and pop it out of the hub the rear bearing will now come out clean everything up and inspect the bearing rollers and the races in the hub for pitting and unusual wear,any signs replace them. Clean the hub up and wipe it all dry, Depending on the seal you choose to use ,I like Stemco myself you will need a installation tool for it. They are available online under 20 bucks.If everything looks good reinstall ,Oil up your rear bearing some and lay it in the race then insert rear seal and using driver set it in place,lube up the outer bearing and have it close by. Pour some hub oil in the hub and slip it on the axle,avoid putting the seal in a bind slip the outer bearing onto the axle and then the washer and nut tighten the nut down just to hold everything in place,Then follow these procedures to adjust your wheel bearing
http://www.timken.com/en-us/solutions/automotive/aftermarket/heavyduty/Documents/Timken-Wheel-Adjustment-Procedures.pdf
when bearings are adjusted ,reinstall cotter key or double nut whatever type the set up is and then,You will need a new gasket for the hubcaps, reinstall the hubcap and fill oil level to the line on hubcap window. I like to use Lucas Hub oil in my steer axles myself You can get it at any truckstop, Fleetpride, TruckPro, Etc. Yes they will sell to you take your old parts in and they will hook you up. I dont think I missed anything. Oh recheck the oil level again after about 24 hrs it can take a while to pass through the bearing rollers after filling to the site line, Hence why you prefill the hub before slipping on axle and before outer bearing is installed. You can do it and were here to talk you through it.

Thanks STUMP for taking the time explaining what needs done on my replacement. This forum is great and the best I have ever been a part of!!!
Chuck and Jeannie saved me on finding the replacement axle!
I just got back after driving to Arkansas to buy the complete front axle.
The poor U225 that was the donor was a burn out and they plan on scraping it soon it is a ONE OWNER coach form corpus christie The engine and trans works good and they wanted $6000 for the set, one owner with less than 50k miles, but I am not sure of that because it has a digital odometer in the dash (looks like a replacement).
I took pics of it and it looks decent on the outside but the inside is beyond rehab. The windshields are good shape and the front side windows are good also. The rest of the glass is broken out. The baggage doors are all good and he gave me a couple prop shocks that I needed. The wheels are Alcoa 6 bolt and all good, tires are old tire code (good tread start of cracking). He wants $250 per wheel.
As for the mechanical and body damage.... insurance it appears they are going to cover my coach woohoo!.
If it wasn't for chuck and Jeanie finding me this parts rig the adjuster was suggesting changing to a newer axle and he could not find one that fit the bolt mounting pattern and one that had 6 bolt lugs, I steered him to the one in Arkansas and I was in business.

I had the coach towed when the accident happened and the tow truck driver said he could not get the driveshaft out and had me leave it running in neutral at idle for the 60 mile tow. He assured me that it would not hurt the trans because the pump would be working on it....I hope that is true. I just went out and started it and it still goes in gear both R and D . I guess I will not know for sure until it is driveable.
Have a HAPPY independence day everyone!

The transmission should be fine leaving it running was the right thing to do.

Are the lugnuts on the driver side right handed and the passenger left handed? Righty loosie in the right hand lug nuts? The top of the bolt says R and L respectively. Thanks and boy are they tight! either way!

Just an update;
Well the coach is repaired, the insurance paid for it. Now it will be a long time before I have confidence in it.

The mechanic said that the bearing got water in it and that caused the failure.
He said over the road trucks usually do not have the same problem because they are used all of the time and the moisture/humidity is vented thru the vent cap with the gear oil being 150 or so degrees the condensation does not have a chance to sit and drip etc...inside the bearing cap.
The replacement complete axle was off a coach with 50k miles and he checked end play and he said they were good.
I wonder if anyone else has had a failure like this?
The mechanic said that to check if the bearing is hot you cannot touch the aluminum wheel to see; you have to reach thru the hole in the wheel and touch the brake drum. The aluminum does not hold the heat like the drum would.

Glad to hear the axle is repaired/replaced.....

I have seen 3 RV blow outs on the side of road last couple of weeks, all front drivers right. Well, I assume blow outs and not more spectacular wheel/hub separations.

I purchased a laser pyrometer to "shoot"past the wheel. I hit rotor and center section of hub...My right side is usually at 112-120 degrees, left front 125-135..... I would love to hear of others temp readings, and what is normal hub temperature? I do a walk around every time we stop to check front and rear hubs/rotors, and hubs on tow dolly, and rear wheels on towed car. I'm hoping that a great many of these failures are "catchable " and will gradually increase temp as problem deteriorates into catastrophic failure.

Howdy David,
I too, "shoot" my tires and wheels temps every time I stop for a break. I always do a walk around safety check. Your temps are in-line with what I observe.

I three shoot the temps on my rotors and hubs with an IR thermometer every time I stop. My TPS checks the tire temps.

Search results for: 'ir thermometer'

I use both the gun style and the pocket style for convenience. Cheap Investment and they go on sale frequently.

If you shop for one of those non-contact thermometers, look for one with a narrow focus angle (distance-to-spot ratio) - makes the readings more accurate when you are not right on top of the target. Also, after you buy it, test the "laser sight" against a known small "hot spot". Sometimes the laser pointer is not correctly aligned, but once you are aware of this you can apply some Kentucky Windage.

I think the posters coach has greased wheel bearings. Not oil?

Re: wheel fell off

Also find IR thermo with a high temp memory. We pull the trigger and quickly run the gun laser over the tire, bearing, rotor, etc, then with trigger still held, read the highest temp. Letting go of trigger resets the memory.
We periodically replaced the red rubber 'stopper' in the end of the hub. After a while the rubber gets harder and probably does not seal as well.
We also have a hole cut in the end of our hub cap allowing us to see the hub oil level, which we check before starting on a trip, along with other oil levels.
