13 replies and no one sees to have given a simple answer to the OP's original question:
Is the sound from the sway bar normal?

Now I am subscribed to the thread also to see if the question is answered since mine also makes torturous sounds when turning. I do not think it is too tight. I thought it might make less noise after it got broken in some but it seems not.

OK Yes the normal design friction sway makes noise when tight and the rig is turning, this is normal and you will soon learn to ignore it.
I have an ACER which is an enclosed design with a threaded rod instead of a plate, it is a bit quieter, but I have only seen the one I have, since I got it 12 years ago.

I found that lubricating the balls (NOT the friction bar!) reduces some of the noise. See http://www.reeseprod.com/support/ins...ion/N26660.pdf for more info.

Here is the product I use:

Husky Center Line TS | Husky Towing

I bought the Husky "Center Line TS" 400-600 books on the hitch, the smallest in this style.
It combines stabilizer and anti-sway, 2 functions in one in this system.
It is also noisy when parking, especially not to apply grease it retains dust and it's worse.
I look for a lubricant that is good but do not trap dust.

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

I'm sorry but I do not consider this an answer to the question of whether the noise is normal (when the sway bar is operating as it should be). Of course the OP (and myself) can back off on the friction, even so far as to eliminate the noise and make the sway bar totally ineffective at the same time. But that is not what you should do. There should be some friction so that the sway bar can do it's job and it seems that if there is enough friction to dampen the sway, then the bar WILL make noise, esp. in slow speed turns.

BTW: I also lubricated the balls (not the bar of course) and for me at least it made no difference in the amount of noise.

BTW #2: When I made an inquiry here about sway issues and mentioned that I had a little sway above between 65-70 I was soundly and widely criticized for my excessive speed. But I only got up to 70 a few times for very short times as I was "feeling out" the trailer and trying to see how good or bad the sway was. I was on the road by myself so those of you who don't want to be anywhere near people who tow over 65 MPH had no worries.

Since the OP has only had his trailer for four days I suspect he was also just getting the feel for it, and probably knows better than to go over 65 routinely. The warnings are appropriate, but I for one would not make the warning with the assumed belief that the OP going 75 MPH was anything more than a short test drive.

ACER should read ACAR as the brand name of the sway bar pictured in my earlier post. I corrected it yesterday but the Edit did not take for some reason. (Thanks Brian for pointing out my error)

Apparently (ACAR Trail Pac) now only makes a sway control of the common design.

Important to note that the party in post #2 DID NOT suggest the OP loosen the bar off to the point that it is ineffective.

Each brand of bars comes with instructions as to how to set them up. I am currently on my 3rd brand and each is a little bit different as to how they suggest you tighten them & how far. For example current brand suggests you tighten it right up and then back it off a 1/4 turn on the handle - previous was a 1/2 turn. The OP will no doubt find the answer to how much is enough vs to much, in the manual for their brand of anti sway bar.

I personally have never had a anti sway bar that makes an lot of noise under normal towing conditions and normal turns - i.e. turning a corner on the street. I have had them make a lot of sound if I make a tight turn with it still in place - such as when backing into a campground. Again it depends of what brand of anti sway is being used but most recommend that the anti sway bar be disengaged when doing tight turns or backing up.

If I owned an anti sway bar that was making a lot of sound under normal towing conditions I would check to see if it was sitting level when connected &/or take a look to see if perhaps the slide is dirty - may need to be taken apart and cleaned.

As a side note in order for the anti sway bar to be level on my old Scamp the anti sway bar ball on the trailer side had to be mounted on a plate attached to the frame that hung down from the frame a few inches to compensate for the slop of the trailers tongue. This allowed the anti sway bar to sit level. Have no idea if the newer Scamps have the same slop on the tongue that the older ones had.

As far a speed of travel goes its a wild wild world. :-) Lots of folks do make it a habit of towing at over 65mph. I know having attended lots of fibreglass meets and had plenty of folks pass me coming and going. So while it may not be your personal practise it may be others

In the case of the OP, due to the trailer being new to them & they gave no reference to previous towing experience it is highly possible they in fact are not aware that speed is a big contributor to sway. And/or that their trailer tires are not rated for speeds over 65 mph.

IMHO, your anti sway bar should be tighteNed to the point where it "groans" when you start out on turns at low speed but is silent once you are up to speed on the highway. Otherwise I agree with most comments above.

Walt do not disagree but then again I do not consider a bit of a groan while doing a turning at low speeds to be a lot of noise. I also know that a couple of my set ups did groan a bit more than brand new than they did after they were used for awhile.

As I said though its always best to consult the manual and what the manufacture suggests is the correct setting up for their brand.

It should also be noted that no one suggested that the party in post # 2 suggested that the OP loosen the bar off to the point that it is ineffective. Only that it could be done and was not what you should do.

In fact, I did try lesser settings and the noise persisted even when the friction was reduced to the point that I felt that the sway bar was a little less effective. I set it back to a higher resistance and just live with the noise on turns.

I have noticed no more, nor any less noise when backing with the sway bar on, but do not do that very often. The only reason my brand recommends removing it when backing is so that you do not over extend it and bend it. If you're angle is not enough to over extend it then backing with it on is OK. The instructions even tell how to to decide if it needs to come off before backing, but the general advice is just take it off and not worry about damaging it.

Good point.. my instructions do mention cleaning it after it is "broken in." I did clean it and the noise is the same.

None of us knows what the OP knows about towing speed and sway until he returns and tells us. Like I said, giving people a caution in case they do not know something is one thing. But (without calling out the poster), I still see at least one reply as unnecessarily harsh and based on a possibly mistaken belief that OP travels routinely at 75 MPH. People assumed I thought it was OK to go over 65 when I said that I did have sway at the higher speed but that was a mistaken assumption. I knew full well the top safe sustained speed was (and is) 65.

I have never heard anything out of my friction sway bar. Maybe it is silent, maybe I am deaf or can't hear it way back there, maybe I play CCR tunes too loud, or maybe I am just really good at ignoring it. I do not have it very tight, although tightness on these things is pretty subjective.

We can rule out # 3. One can never play CCR too loud.

This is interesting because I really do think if I adjust my sway bar to the point it is quiet in turns around town, then when I get on the highway and swerve a little to try and judge the effect on the trailer swaying, the sway bar does seem to be less effective in returning the trailer to straight tracking as fast as before. Perhaps it is still OK but I can't tell since I won't push it to the point of being unsafe. Perhaps if the sway was that bad, the bar would do something. I just don't know.
