Sway Bar Noise

We picked up our new Scamp 4 days ago. We had Scamp install a sway bar.

Since then we've driven about 800 miles with no sway at all, even at speeds as high as 75 mph


But the sounds that come from the sway bar, especially when turning, sound like a torture chamber. Is that normal?

The sway bar depends of friction to work; you might have it a bit too tight. Do NOT lubricate it!

I'd back off a bit and see how it goes. Still no wiggles when big trucks pass, you should be good.

The tires are rated for 65mph maximum. Exceeding that for any length of time is asking for a blow out.
I tow my 13' without an anti-sway bar. No problems. Anti-sway bars, at least in my opinion, will mask a problem that should be corrected.

I don't see a problem with using a sway bar... as long as you first establish that the trailer is stable without it under all normal towing conditions. It's meant to be an auxiliary safety device in an emergency situation.

I agree that 75 is way too fast!

The problem I see is that many people put on an anti-sway bar to correct a problem, not as an added safety device. In my opinion an anti-sway bar is dangerous in some conditions. I've never used one and travel a lot. 10K miles so far this year.

You all might have to stay home a lot, as I regularly see trailers being pulled at speeds near 75mph. I have done it too, as my tires (and most ST tires) are rated at 65 at the minimum rated pressure for the weight of the trailer, but if you can increase the pressure by 10 lbs without exceeding the maximum, they are rated for 75. Still, the fastest I usually travel is 110 kph (or 68 mph), the speed limit on many highways here, and only exceed that on rare occasion.

I am of the same mind as Jon, that there is no problem using sway control, but just so long as it is an assist, and not covering for a loading problem.

There really should be no excess noise though, I too would back off a bit on the friction.

I see a friction sway bar as a luxury improvement.
It hides nothing. In fact I think it shows a dedication to excellence and improvement after all else has been done.

Besides , a "MASK" can sometimes really improve your game!!...

need a pic....

quite a few people around here confuse sway bars with weight distribution bars....or at least say one for the other....

I have a standard WDH that came with the trailer (no anti-sway bar or bars)...I used to hear a lot of noise back there making turns (clanging/banging) then I greased the ends of the weight distribution bars that fit inside the hitch and the noises dissapeared

made sense once I'd done it...during a turn the ends of the bars would have to rotate a little...metal on dry metal with a whole lot of torque involved...they would bind up....with a little bit of grease they don't anymore

I agree but I suspect neither of us would ever tow at 75 mph either

The key words in the above are "after all else has been done"

Actually If "key" words must be taken out of context they might be "it shows a dedication to excellence and improvement".
It was never I who suggested that friction sway control was a band-aid. It is an effective supplement to good system.

Totally agree assuming of course that ALL has in fact been done to set up the trailer to make sure it is a good system!
