F-53 Chassis sway bar issue!

Almost forgot to mention,

If you are driving a Ford F-53 chassis and is less than 3-4 years old, take a look at the rear sway bar mounting brackets. I had an issue in August, while driving I noticed a little sway and roll, just chalked it up to the wind. While underneath my coach looking to route a grounding wire, I noticed the mounting bracket for the passenger side sway bar was bent. It appeared the head of the bolt sheared right off and the bracket had bent upward and the sway bar had slid partially out of the bracket.

The ford truck center fixed it under warranty, approx 45 min fix. The service rep stated they have seen a few of them broke in the last year or so. He didn't know if it was a batch of bad bolts or if they were being over torqued during installation. At any rate, he explained that they only seem to fail in the first year or two and if you make it more than 2 years then they won't fail!

I just happened to stumble upon my broken piece, I've since added it to my monthly inspection list! Hope this helps!!!!

My unit is a 2014 Miramar 34.2, at the time I had less than 5,000 miles on the coach!

Sway and roll

Notice a lot of sway and roll when truck passing on in light wind. Just purchased this 2012 Challenger KT. Are there kits for these F53 to keep the roll down.
Thanks
Roger

Hey Roger,

I've looked around Amazon at different sway bar parts and accessories, there are a lot! If you can take a look at some of the customer reviews! There are some interesting comments! Prices seem to range from 59.00 all the way up to 800.0 plus dollars!

What years does the recall cover?

Common problem for 2014 and 2015. If you check and they are good i would still remove a bolt one at a time, nuts are welded to the frame, add blue loctite, reinstall the botl and torque to 66 ft lb

There are 2 bolts for each bracket. If you have an impact wrench it should talk you more time to crawl under the mh than to do this fix

Had the same thing happen on our 2018 Miramar. I was hooking up the safety chains to the towed and I saw something hanging underneath the motor home. The bracket was hanging down and one of the bolts was missing. The bracket was bent so I had to get a new one from Ford. Sounds like this is a common problem on the F53 and has been for several years.

I'm confused and not very mechanical. I learned that the c-bracket on the sway bar on the left rear side of my 2013 Hurricane is broken. I asked my repair shop about this and they said they cant simply replace the bracket, the sway bar has to be replaced. Does this sound correct? Any insights to this situation wwould be appreciated.

I have read several reports about the bolts falling out and the "C" bracket being bent or missing. But I have not read where the sway bar has been damaged by this.

I would say they are trying to create work not needed. It is possible that yours is damaged but it would be the first Ive heard of.

What could be damaged or needs replacing is the poly bushing that circles the sway bar and this is what the "C" bracket is molded around.
Poly bushings are very cheap and can be found on ebay by skuterdude, an IRV.com member.

that is interesting. While having my Road Master sway bar installed the shop had to cut off the old bolts. The stock ones were so tight the impact and pry bars couldn't budge them.

I've got about 7500 miles on my 2017 Challenger 37TB and all looked good with my sway bar mounts when I did the CHF on the rear. Made a pretty big difference in the wallow it did. Just need to retry the fronts. Had it up on the leveling jacks and the bar would not move far enough to get the bolts back in with the springs partly unloaded. I think it will bind on the springs if I move the links to the other hole...

When doing the chf you should not raise the mh with the jacks.

I have heard of people having problems getting the bolt in because of the spring. Fortunately i didnt.

But i didnt like the angle of the bar in the chf position. So i made these brackets to lower the bar to the stock angle and i still get the chf

halfprice I see yellow shock tubes, and am assuming them to be Bilstien shocks. Did you add them, or is that what came on yours ? Mine are Black not sure what they are.

They are Bilstien shocks and they were stock from the factory.

If i ever need to change them id go with the Konis. From the little research ive done they seem to be the best out there
