Have you ever scaled your rig? I found that a small difference in TV front axle weight made my 34' tow like crap (I also have a Hensley). My setup tows fine with the WD bars cranked fairly tight even though I lost 130 lbs or so of front end weight, BUT if I loosen them just a little and the front of the truck lightens another 150 lbs or so we wander all over the place.

Good luck.
I didn't scale the rig on this outing... I figured because I didn't do/load anything different, it wasn't necessary...

I'll be scaling it once we hook up (and may have learned my lesson...)

I did not tow anything during that time, but I think it would have affected the towing to be constantly correcting the steering.

Ken,

My tire guy at Discount Tire told me same thing.. he actually tried to talk me out of the LTX AT2's because he said the 'aggressive tread' pattern would adversely affect towing performance...
Because I'm an expert in everything, I 'pishawed' him...

It's probably your tires. I have a Ford Excursion V10 that towed beautifully until I changed tires. We had to stop while on the road to purchase new tires. The dealer sold me Firestone AT 265/75R-16. I couldn't keep the Airstream between the fenceposts. I tried adjusting our Reese hitch several times with no success. I, too, came home with white knuckles and wife with frizzy hair. I took the car to my local tire dealer, and he said the problem was the tires. He swapped out my AT (All Terrain) for HT (Highway Tread) of the same size. We've had no problem since the exchange. Hope this will help you with your problem.

hi fc'

bummer dude!

i don't have 1 of those fancy orange things but that doesn't seem to prevent OTHERS from giving advice so here's some...

start with the tires, many tires of/with SIMILAR tread designs are squirrel-y for 500-2000 miles.

i've almost taken back tires for this reason, but eventually they settled down and preformed fine.
_______

the bearings on the haha MAYBE need repacking every 4-6 years depending on use, water exposure and storage...

i think HIHO can give u some insight into how the grease ages...

(he might even have some pictures...)

but old dry grease isn't the cause of your symptoms.
________

IF the struts were loose OR a shear bolt failed, the front end of the TRAILER...

would be ALL OVER THE PLACE side2side...

it's a VERY dramatic experience and can definitely affect the tv rear end...

but you would SEE a very wiggly trailer back there.

(still a good idea to check struts and shear bolts, but that's not the problem either)

the HOLES on the hitch HEAD for the strut PINS can lengthen, so check them too...

but again that would cause LOTS of trailer wiggle, seen in the mirrors...
__________

the w/d bars BUSHINGS and grease zerks wear and can IMPEAD hitch performance...

but the typical symptoms are TURNING issues, not WIGGLE...

and the hitch head would NOT move freely as u've reported.
__________

most DEFINITELY if the w/d is NOT dialed in the truck will handle poorly....

LIGHT steering, the need to OVER correct for turns/wind and ruts are the clues...

but the burb BACK end should look LOW, the tires bulged, head lights UP and so on...
__________

so it's back to the tires, or leaf springs or shocks or rear axle on the tv...

are u SURE the tires are at 75-80 psi?

check all the normal stuff on the burb' and let us know how this goes...
___________

one MORE thing to inspect (but you already know this...)

CHECK THE RECEIVER for cracks/loose bolts and so on....

those OEM ge'em receivers aren't very good...

cheers

It may make you feel better to know that I have towed with the tires since they settled down, and they do just fine.

When not towing, they have been a big improvement over the OEM tires in the snow and mud.

However, when they wear out, I will get something a little less agressive so I don't go through the break in again.

Ken

Ken,

No question... I replaced Firestone Transforce HT with these Michelins, and they are superior in snow, mud, and beach sand

Didn't notice any difference in ride... did notice more road noise...

Something, somewhere, is loose. I'd bet my paycheck on it.

I don't think its the tires. Could be wrong on that though

Unbelievable?

Hi, are you guys pulling my leg? Is this some sort of April Fools joke. Sway, white knuckles, almost ended up in a ditch; All this with the famous, fool proof, sway eliminating, miracle hitch. I just paid half a fortune for my new glasses and can't believe what I am reading. Can this really be true? I thought you could tow a 34'er with a Jeep CJ-5 [83" wheel base] with out sway concerns. I want to hear from the Orange Hitch company now.

Talking Do you mean....

I saw a video of a "Touareg" just like mine towing a "747" and it had no weight distribution or anti-sway device installed....

It towed straight and true - no issues at all - for all 100 yards in a straight line down the runway with no turns...

You mean to tell me that there isn't full disclosure in advertising and that all forum members are not Airstream towing specialists? Next your gonna tell me the tooth fairy, Easter Bunny, & Santa are all myths...

If you noticed sway after putting on new tires, then that is likely what is causing the problem. I experienced the same thing just towing a 20' Airstream with my 1/2 ton.

However, if it isn't the tires, then check the welds on you GM hitch. More than one owner has had a weld crack and/or separate using a Hensley. That particular hitch seems to put more stress on a hitch (200 lbs. more weight + torque to achieve its touted performance). At least some of the GM hitches only have a weld on one side of the receiver. If yours is like that have it welded on both sides even if its not broke.

UPDATE ON MY PROBLEM:
I talked with Terry Powell at Hensley hitch on the phone, we went over several things about this hitch, we came to a few conclusions;
1) figure out if it was hooked correctly, if it is proper working order, use as is.
2) I pay and have the hitch reconditioned at $75.00 an hour min 3 hours +parts.
3) they buy the hitch back for $450.00 and I use another sway hitch

Now what is going to happen I am going to follow the steps he gave me to see if everything is in working order, then I am going to adjust it as he suggested and tow it some more to see what happens. If it is still an issue then I will swap it back to my current sway hitch that I had on my 31 footer, and install the suspension add ons that I had planned on before I got this trailer with the hensley. Sell the hensley.
I am also going to get rid of these mich tires and go back to Generals, they cost a little more but they are made for these purposes, and will get rid of the tire sway problem.

Was the hitch set up like in this example?

Sarge- the 'pivoting' action is normal operation for the Hensley

We know the hitch is installed correctly- it functioned for +10k miles flawlessly

There are no obvious failures- strut bars look OK, no elongation on holes, no failure at the spring bar mount posts, centering latch intact (swings clear with shank)

I upgraded the GM receiver before buying the Hensley... using a Class V 'Tow Beast'. There doesn't appear to be any failures there...

The hitch pivots smoothly, and there doesn't appear to be any 'play' in the receiver assembly, i.e. I don't think we're dealing with bad bearings

2Air- I think you're right (verified psi).. we're dealing with something on the truck. The feeling in the burb (with the steering), is very similar to the feel (although not as bad) I had in my old CJ-7 when the caster was out of wack... the only thing I can do now, is to take it slow on the way home, and have a real mechanic check it out (AOT going somewhere around here and having bushings, bearings, connectors, arms, etc.. changed out willy-nilly)

It appears 'The Arrow' has some limitations after all, in that it doesn't 'fix' the tow vehicle...

I'm putting my money on the tires being close to worn in and the towing much improved by the time you get home.

Good luck with it,

Ken
