Dangerous Bus On The Highway! Several shocking discoveries on this Prevost bus

[@johngaither9263]

What does it take to get those bearings to fail completely? Is it even possible?

[@BusGreaseMonkey]

Funny you should ask… check out this in our shorts channel kzbin.infoyGkru0AeRIE?si=LZw7PbGPbdDRAM1P

[@charlesb4267]

Oh they will fail all right, to me that looks like water got into the hub oil and rusted them badly, then driven and things really went for crap. Wouldn't be much longer and that outer bearing would fail and the wheel would lean over/wobble and the brake drum would be riding on the brake shoe and some interesting steering handling to say the least !.

Everything fails sometime. Wasn't that far away. Who signed off the last inspection. That much stuff doesn't wear out in a year.

[@jamiesuejeffery]

As a former driver, and driver only, I noticed two (well three things) that if I were to be assigned to that bus in the first 4 minutes of this video that I would have demanded another charter coach and refused that one: 1) lug nut covers. Don't do it. They hide multiple sins. 2) the wrong stud size for the attached rims. Change the rims, change the bolts! 3) obscured hub oil caps. You cannot see what is happening inside the hub if it is obscured. Don't do it! On my daily pre trip there were a bunch of things on our checklist but the things that were always included were rust stripes on the lug nuts. That is a loose lug nut or something worse. Two, if the lugs don't fit, then you must reject! Three if you can't see the oil, then a hot bearing will absolutely ruin everyone's day! I'll put up with 3 pounds of air loss a minute, but that is the law. If I take that coach out of the yard and the brakes feel like mush, then it gets dropped right back in the yard.

[@andrewdonohue1853]

i am a commercial truck driver myself and i noticed no sight for the oil level in the hub. i once had the sight break on a hub and i had it replaced immediately. im a local milk hauler so i wasnt too far from the shop at that stop. i periodically look at the truck any time i am stopped. if i can hear air hissing or something doesnt look right, i have it corrected. yes i look at things before i leave, sometimes you can pick up a nail or a screw at a farm that wasnt in the tire before you left. it's an on road / off road type of job things happen. i formerly drove dump truck and i once picked up a valve from an engine at an old steel plant that was recycling old metal. that was the weirdest thing i have ever seen in a tire, an engine valve. i reported it to the company i worked for at the time and they replaced the tire on-site. it was a steer tire, if that went unnoticed that would have been bad.

It amazes me just how many bus owners don't have the knowledge or the effort to do the necessary maintenance on this equipment they own and drive on our highways with us. Not only risking their own lives but ours also. I sure hope you stress to them the importance of regular maintenance checks and how if they cant afford them they shouldn't be driving them.

Most buses you see here are new purchases and they come here right away.

[@charlesb4267]

That wheel bearing reminds me of one of my highway tractors I bought used years back and from a company who had it from new and they were known to do a fair job of maintaining their equipment. I brought the truck to an alignment shop right after I bought it as I knew it needed some work with the way the tires had wear and it pulled to the right ( needed the caster tweaked ). Well turned out one of the outer wheel bearings was failing as the mechanic felt a bit of looseness and pulled the hub and the rollers poured out of the outer bearing as the cage had failed, a few of those bearing rollers looked like square key stock.

[@andrewdonohue1853]

wow, that's bad. really bad

[@josephalberta1145]

I dont spend a hundred grand a year on my bus but I do take it in yearly for a good check out. This year I had to replace the slack adjusters. Prevost sent different ones so we also had to replace the brake cans. Found a worn out bag on the tag axle and replaced that too. Other minor items that could have gotten worse. A bit of money gives a lot of peace of mind.

[@andrewdonohue1853]

[@boriskarloff6356]

I love watching the work you guys do, admiring from Tasmania, Au.

[@charlesb4267]

After seeing what you found so far, one has to wonder what ugliness might be in the engine due to lack of not only oil changes but lack of coolant changes. Had the interior been in top notch condition is one thing but with that rating below a zero, and the diff more than likely needing a reman third member and all wheel bearings probably need replaced, etc etc etc, brake pots I'd say, compressor, air drier ... and ... and .. and !. Is it really worth the funds to bring it back to its former glory. Sadly from what I understand if one expects to stay at some campgrounds, they turn older RV's away so no matter how nice an older unit is some places will turn a person down flat.

[@aussiebloke609]

So many vehicles are serviced according to how many miles they do, with the attitude of "it doesn't need it, if it hasn't gone anywhere." And this seems to be the result.

[@BusGreaseMonkey]

People always ignore the “or # months” in the maintenance intervals

[@asarand]

I am surprised that that wheel was still turning. By the looks of those bearings that should have been frozen.

[@BusGreaseMonkey]

It was very close to that b

[@jeffbyrd7976]

It's amazing how durable those bearings are, just imagine how those look that fail while in use. I have heard mixed reviews about Prevost, does this indicate poor construction as well as neglect? I watched a video of a guy who had to rebuild his differential on the side of the road. He had managed to get to a rest area, and spent a few days there. Makes me proud of my coach.

[@BusGreaseMonkey]

All these failures are exactly the same part numbers as other bus brands. Possibly more weight by like 10-15% on them could make a difference but not many variables in the equation

[@toneman501]

Judging by the wear and damage , I'd say the odometer has been clocked over... There's no way it's only done 87000 miles...

Watching this channel (I’m a big fan) makes me avoid bus campers on the highways. Seems most of them come into the shop in this condition - ready to lose a wheel or their brakes. Crazy. People get into this “hobby” similar to boating…seems like a good idea, so let’s buy one and just drive it around without understanding how to treat it or maintain it. Good for your business I suppose.

[@nvragn]

Hey there I'm a 30 plus years as a heavy truck mechanic and don't ever remember seeing the washer that goes up against the bearing threaded. So is it safe to say that you set the preload with it instead of the traditional inner and outer jamb nuts. Could it possibly be that way because it's a coach and they do things differently. We all now coaches are 24v so that's different and I'm sure that there are alot of things done definitely. Ya I just stumbled across this video and knew that I just had to take a look Ty for putting this this type of thing so others can see if they choose to. I'm definitely going to check out your channel 👍 🇨🇦

[@CenturyHomeProject]

It's amazing just how much engineering goes in to these rv's.

[@forestpagan4813]

As a commercial truck driver, there are two kinds of vehicles to avoid as much as possible: RV's , and rental trucks. Not so much from lack of maintenance, but because their drivers usually have no clue, or skills necessary to handle them under emergency situations. (For some, it's a challenge to stay in a lane on the expressway)

After over 31 years driving trucks (heavy-haul, windmill blades and now oilfield winch trucks in North Dakota), thisss is why I have come to hate the big coaches, rv's and 5th-wheel campers on the road these days. They should be held to higher standards of inspection and driving just like the big trucks and what we're seeing in this video is a prime example of why. If it wasn't so dangerous, I would have laughed at those bearings! Wow... Chills down the spine... I guess the "entitled" class can get away with murder, though... smh

[@BusGreaseMonkey]

I wouldn’t call them entitled class. But there are no education or experience requirements required to get behind the wheel of these 30-60,000 lb vehicles and that is scary to me

It would be great to someday see a video possibly called "The True Cost of Owning and Maintaining RV's and Bus Conversions". This would be aimed at current owners and potential future buyers of this large equipment of what is required to keep in proper repair as well as expected maintenance and inspections to keep equipment in safe working condition. And as you and I both know and you stated in this video, equipment which is parked for long periods needs as much if not more attention than one rolling down the highway on a regular basis for various reasons. It is not wise to purchase or own this type of equipment if it will only get used two or three times a year. As for me, I'm doing good since moving to Tennessee two years ago. I switched to a new dump truck company in Franklin 2-1/2 months ago and they are very good to me. So glad not owning and working on my own trucking equipment anymore, those days are now in my past. Maybe some day we'll meet again as I live 20-miles south of you. I assume Tyler is still down here somewhere?
