This may have been mentioned already, Im still in the middle of reading this thread. When I purched our Airstream with a HAHA, the tech actually told me to use Go-Jo instead of grease on the stinger bar for lubrication. It seems to work OK. It still hurts like hell, but doesn't stain.

For the past 6 months I have placed a red grease rag over the stinger when I leave it in and my jeans are a lot cleaner. Still have the pain, but not the stain. And the red rag makes it more noticeable to others who may walk by so they can avoid it.

If I move the TV to go get fuel, etc, I wrap a short bungee around the rag and hook the ends through the clip pin holes. Works like a charm.

Rich Luhr has just posted an incident he just had with his haha on his blog. Too hard to cut and paste the link from my iPhone.

But he lost his WD bar enroute and only knew it since his better half was following in their new car.

It appears it may have failed due to fatigue from not greasing the hitch at recommended intervals when first installed.

morning hitchin' buds...

the part that broke is pictured here..

http://www.airforums.com/forums/302952-post89.html

and in the next post #90.

the 'greasin' issue is specific to the w/d bar heads where they insert into the main haha body...

shown in posts 91-95 above...

there may be other and several issues contributing to this/his specific part breaking..

but YES YES YES grease those bar heads!

that's why there are grease zerks in that location folks.

and another caution...

should your spring bars fall out in camp, or drop partially out, or bind in the slightest AT the bushing/head...

CHECK THE GREASE ZERKS FOR DAMAGE...

it is very easy to grind, break or otherwise bugger up the inner zerk tips...

so carry spare zerks, and a grease gun,

and check this area each time you disconnect/connect...

cheers

Yes, 2air is, as usual, correct in his point: grease is good. The blog entry speaks for itself but I'll add a few things to further the conspiracy:

1) I've been using a mini grease gun, to keep the load of equipment in my bumper compartment to a minimum. But it takes 40-50 pumps of that silly little tool to fill the grease chambers every 500 miles, which is part of why I wasn't doing it as much as I should have initially. I'm switching to a "big boy" grease gun.

2) I have noticed (long ago in my misspent haha youth) that lack of frequent greasing can cause wierd tracking issues. GREASE GREASE GREASE as 2air rightly recommends.

3) I've already replaced my zerks twice due to having worn off the nubs and will be removing and replacing the current ones to check them as part of this repair. I carry a spare set because you can't just pick them up anywhere -- not a hardware store item. They do wear out in normal use, so expect it.

4) About 20 minutes before this failure, we crossed over a VERY rough train track. I was caught off guard by a severe bump at about 20 MPH and my wife who was following reported that the wheels of the trailer actually left the ground! This may have overstressed the bracket, leading to the failure only a few miles later. So I can't state the cause of this failure conclusively. It may be a complex set of issues.

5) Non- haha owners take note: this U-bracket and bar arrangement is used on other brands of hitches -- and I was told by a dealer that the bracket is a common failure point on those hitches as well. It's not an issue exclusive to Hensley.

Thanks for the update Rich. I was just out at our trailer this morning going over everything as we're about to venture on a 3 week trip out to the Grand Canyon area. (A 5,000 mile round trip)

I've insured my haha has been properly greased, checked the torque on the nuts securing the hitch brackets, checked tire pressures and checked those lug nuts too.

I too keep a grease gun and plan on picking up additional refills as I'm down to one extra.

My wife and I will be posting a blog of our trip and will post a link to it in a new thread.

Glad no other damage was done to your rig Rich!

thank's for the additional info rich,

here in the repository of all things haha...

it's seldom just one thing true, true.

and high mileage users gotta do what they gotta do...

my concern was that some less familiar with the inner workings of these doodads...

might interpret 'grease yer hitch' as grease the stinger...

messy, messy, messy, as tin sista might say

as with all hensley controversies,

i'm pretty sure this contraption can be traced to medieval french drama...

which would make it a...

brouhaha...

cheers

Cracked U-brackets

OK, I replaced both U-brackets on my hitch and I advise other owners to go check theirs if they have a lot of miles.


See larger image at:
http://tour.airstreamlife.com/weblog...des%20rust.jpg

I talked to some more knowledgeable folks about this and they said that if the part failed due to metal fatigue, I'd see a rust line where the metal has been breaking for some time. In the photo above, you can see a clear rust line on both of the broken sides of the U-bracket, as well as sharp shiny steel where it finally broke.

You can also see severe stretching of the holes where the pin ties this U-bracket to the screw jack. This part needed replacement.

See larger image at
http://tour.airstreamlife.com/weblog...%20bracket.jpg

You can see the same metal fatigue rust line in the second photo, which shows the remains of the bottom part of the bracket. Also note distortion in the plate from the last bits of metal bending before they broke.



See larger image at http://tour.airstreamlife.com/weblog...%20bracket.jpg

The last photo (above) shows the other U-bracket. At first glance it appears OK. It's very hard to see in this photo, but the upper corner has a distinct crack in it. It was already in the process of failing! This crack is so subtle that you would not notice it in a casual inspection. You really have to look closely.

I will be replacing both U-brackets annually from now on.

oh yea baby!

i can definitely see the rust in your crack!

it appears this u-bracket is the same piece on the 1000 and 1400 lb bars...

with that much MORE stress on the heavier bar users...

so it may be that your gradually failing u bracket broke on the rr tracks,

then it took a few miles for the bar to work itself out and fall...

u r really lucky 4 no trailer, gas line or brake line damage...

excellent post!

cheers

Rich,

Thank you very much for taking the time to post this information. I just purchased a haha in June, and will be keeping an eye on those U brackets. Do you have any idea how many miles were on those brackets before they broke?

Thanks again
Dale
