Critical Lessons After Axle Failure and Wheel Loss on the Road

Thread Summary

Summarized on:
This AI-generated summary may contain inaccuracies. Please refer to the full thread for complete details.
Several RVers shared firsthand experiences with catastrophic axle and wheel failures, emphasizing the importance of regular bolt and lug nut checks. The original poster described losing a wheel due to sheared lug bolts and later, a sheared spring centering bolt that caused the axle to shift, both traced back to loose or improperly torqued hardware. The consensus is clear: always carry a torque wrench, know your torque specs, and check all critical bolts frequently, especially after long... More...

We purchased our 2017 27RL Reflection new and have pulled it thousands of miles across the country in the past 8 years. I've learned a few things the hard way. Nothing beats experience and I've gained some valuable knowledge.

The first major problem I had was losing a wheel. After packing wheel bearings one spring we traveled to Colorado and other sites closer to home. No issues until the last trip of the season. One wheel totally sheared all the lug bolts off at the drum. I have no idea where along this 90 mile trip it happened but I was not aware of it until we reached the campground. Knowledge gained.....carry a torque wrench and constantly keep your wheels tightened to the appropriate torque. You will not feel or hear a loose wheel like you will on the vehicle you are ridding in. Lugnuts can become loose!!

Early this season we were heading down the WV Turnpike and I suddenly realized the trailer was rolling along rather sideways!! I stopped at the next exit and discovered the front axle was not in alignment. The bolt that runs through the springs and actually centers the spring to the axle had sheared off and was missing! The spring had actually slid apart and the axle slipped back 6 inches. I come to the realization that the u-bolts were not tight and through the thousands of miles we have pulled this trailer it allowed the pin or bolt that holds the springs together to wear thin and brake off. Now there was nothing to keep the spring centered on the axle. Luckily some good people stopped to help. They drove to a hardware store and purchased a grade 8 bolt and we were able to pull the springs back in alignment, put the head of the bolt down into the hole on the axle and then tighten everything back down I checked all the other U bolts on the other springs and two were rather loose!!!! These u-bolts are supposed to be torqued to 70-90 lbs depending on their size. It's critical they remain tight! If the axle and springs are allowed to shift then the pin in the springs can wear out!!!

So here is some very good information. Carry a torque wrench and check your bolts everywhere on the trailer. Get the torque specs and keep an eye on things as you travel. An over tightened bolt can break or stretch. A loose bolt will eventually shear off. Goodsam road service was totally unwilling to help. All they could do was dispatch a tow truck. They could not offer a phone number to a local RV tech or emergency road service. I explained that the trailer would not roll but they said all they can do is tow it or change a flat tire.

You are on your own when traveling. Carry spare springs, jacks and tools. You may end up fixing it yourself!!

Obvious words to tow by. Unfortunately, you cant carry it all.....

Doing (noted/documented) research of mobile techs and/or local parts distributors in areas that will be traveled (ahead of trips) would be helpful incase of such calamities when you cant carry it all.
 
That is no fun, it's good you got through it wothout any further issues.
We lost a hanger bolt a couple years ago. Another did not feel it but noticed black rubber flying off a new tire as we drove down the road. Luckily we were not far from an exit. mid afternoon on a Sunday in KY. Luckily we were able to locate a mobile tech to help and chase bolts plus align the spring back into place and put the spare tire on in 90+* weather

:cry: Been there, not fun. Wise advice.
 
Don't feel like an RV dealership is the only place that can service your rig. Look for diesel mechanics, trailer shops (18 wheeler), fabricator, welders.

Lots of people out there with skills. Showing up with the spare parts you need really speeds up the process.
 
I have had bolts come loose, causing issue's over the years, now at the beginning of the season, I check all bolts, including brake caliper bolts, then torque stripe them. Through out the season, it is easy to see if something is not right.

Same issue in northwestern MN. (Aug. 2024) with Momentum 351, fortunately a good samaritan waved me over on Hwy 2 as I did not see or feel an issue. Very good advice, I now carry a spare spring with hardware and appropriate tools/jacks to do this again if necessary. Getting mobile help from GS was painful, but Grand Design customer service was exceptional with sending factory replacements to the campground I limped it to (with a substandard spring) as I was still under warranty.

If you have a TPMS, it will inform you within a few seconds of loosing a wheel because once the wheel is at least 50 feet away, it no longer senses air pressure in that tire and that will trigger an alarm.

Not necessarily. It will depend on the amount of time it takes for the unit to recognize that it no longer is getting a signal. Hopefully, TST has changed, but ours can take an hour for the unit to realize that it is no longer getting a sensor reading.

The best way is to leave the TPMS on, and drive away and see how long it takes to alert.

My tire Traker system will not immediately notify either

I guess it depends on the brand of TPMS. My Guta brand TPMS alarms within 3 seconds.

Been there. Somewhere in Montana, my right rear wet bolt departed. Never noticed anything while driving except I could not get my drivers side tow mirror where I wanted it. We were at East Glacier and getting ready to move to West Glacier for a few days checking lug torque and the RR tire rolled forward and hit the RF tire. Temp fix got us to West Glacier. GD re-routed one of their mobile techs to weld on two rear hangers and sent a pallet of parts. I have 4 extra springs in the pass thru. While there, a Momentum pulled into the campground adjacent to us with the exact same problem.
