Trailer sway can be seriously scary...

Today I finally decided to move my parts car, a '90 BMW E34, off my
parents driveway and instead park it in their barn about 50 miles
outside the city. Apparently neither my parents, nor the neighbors,
liked it there, and not having valid registration and no insurance it'd
be illegal to park it in the street. Figuring, how difficult can it be,
I took my newly bought '90 Cherokee, rented a trailer and drove over
there. Long story short, after looking for the keys to for about half an
hour I was ready to go. My dad thought it would be fun to come along,
which turned out to be a good thing. Anyway, loaded the car on the
trailer and hit the freeway.

At first everything was fine, but that quickly changed. Going up a steep
hill I was hard on the gas to maintain a steady 60 km/h, and after
reaching the top the speed increased. Talking to my dad I wasn't paying
attention so I don't exactly know how fast I was going, but I guess
around 90 km/h, maybe more. Then all of a sudden both the Jeep and the
trailer started do sway back and forth. Not sure what to do I did
nothing but ease off the gas, but the oscillation increased. Now,
realizing that this is *not* good, and knowing that if I didn't
straighten it out we'd sure have an accident, I was trying to think of
what you should do in these situations. All I could think of was either
do nothing or accelerate and pull the vehicle straight, deciding that
accelerating might only get me in more trouble I just kept my foot off
the gas. Finally, after swinging back and forth maybe ten times with
increasing strength the rear wheels on the Jeep lost traction and it
started going sideways. This might be what saved us, because I think the
surge brakes on the trailer kicked in at that moment. Either that or the
sway transformed into just pushing the Jeep sideways. Needless to say,
having owned my Camaro for ten years I know how to handle oversteer, so
after straitening it out everything was fine. I must say though, that
was the most frightening I have experienced pulling a trailer.

It was a bit funny though that after that, and despite going about 40
km/h below the speed limit, it took a while before other drivers dared
to pass us. The rest of the trip I kept the speed under 80 km/h on the
freeway and 70 km/h on the two lane highway. I did pull over twice, the
first time after driving on a long straight and seeing cars behind me
the entire length. I started counting them, but I lost track at about
30. I estimate about 40 vehicles were directly behind us, but only one
honked and I'm not sure if it was a "get off the road" or a "thank you
for pulling over" honk. I hope the latter... :-)

Anyway, aside from that everything went smooth, except that all four
wheel chocks had moved around and were useless, the tie down on the
right wheel was loose and that the tilting bed wasn't secured. And, of
course, the lights on the trailer didn't work either. First time pulling
a trailer with the Jeep and I suspect the trailer light wiring is not up
to par.

Ditto.

While I've never personally pulled a trailer, I've ridden with a
number of relatives who have towed tractors, boats, cars, and trucks
behind their vehicles. Never experience trailer sway.

What I have heard, though, is that if you experience the situation,
you don't have your load properly balanced, and you need to stop and
correct the situation immediately.

Actually, I drove past work today to have a look at the Jeep on the
hoist. Turns out the left rear wheel was loose! The idiot PO apparently
doesn't know how to tighten wheel bolts properly. An other thing I
noticed, and which I suspected, was that the rear axle is leaking oil.
Added about 1.5 liters so there couldn't have been much left in there...

But which idiot doesn't check what their life may depend on...?

I guess it hasn't occurred to you that you're no less than perfectly
unqualified to pull a trailer...?

I guess they don't teach class c drivers how to do a proper pre-trip.

Actually, I have a Class A license. But come on, the trailer was only
weighing a bit over 2 tons, I should have been able to pull that thing
in my sleep... With that said, I wasn't really in a good mood when I
picked up the trailer and found out the lights didn't work, and I didn't
get any happier when I couldn't find my keys to the car! Then add in the
fact that I was trying to get it done in four hours to avoid having to
pay extra to rent the trailer. In retrospect, a bit more planning
wouldn't have been a bad thing, IMHO...

If you have a Class A, why did you accept a trailer without working
lights? Ya gotta know that is a prime excuse for the DOT to pull you over  
and make your trip hell. I know this was a personal trip, but, you seem
to be thinking like a 4 wheeler. And if the lights aren't working what
else is wrong that isn't obvious? It's scary reading about that trailer
trip. You don't want this side trip jepordizing your livelyhood.

Hey, I know the panic of losing keys. I usually find them...in the
ignition...with the doors locked...and engine running.

Because I suspected the problem was with the wiring on the Jeep, not the
trailer. Complaining to the place I rented it from because of a problem
with my own vehicle would have made me look like an a.s.

I was in my own vehicle on my free time. I was solely responsible for my
actions, had there been any repercussions.

And if the lights aren't working what

Again, what does it have to do with my work. My time = my business. The
only way I could have lost my license would have been if I was charged
with reckless driving, and driving without working lights doesn't even
come close. It's a simple ~$150 pay-and-forget ticket last time I checked.

I found them in my washed shorts I hadn't used in a month...

Ulf,

I didn't mean to bust your chops over this. I just wanted to give you a
wakeup call. I assumed that since you hold a class a, you make your
livelyhood driving large vehicles as I do. I'm very protective of my CDL,  
and I don't do anything to jepordize it. I'm sorry I projected my
assumptions onto you.

I used to, but now I have a job with regular hours. I liked driving a
truck for a living, but it just got too stressful and I never really got
along with my boss. When I applied for this job I was asked to bring a
printout of my criminal record, and all traffic violations are criminal
offenses around here, but when he saw the two pages he just laughed.
Likewise, after I did a WOT acceleration across the parking lot in a
customer's modified Audi S4, and let off to make the turn around the
building I saw the faces of three people who just spun around after
hearing me come. Recognizing one of them as my boss, I expected getting
crap for that. When he came in later he just said something like "don't
you just LOVE that wastegate sound!" So, in short, I don't think I need
to worry too much about getting another ticket...

Sounds as if, effectively, you did.

Does 2 tons seem too insignificant to control?  Your load wasn't
secure, your tilt bed wasn't secure, one wheel wasn't secure...  I'm
wondering if the ball had a nut on it.

I thought it appeared in the pics that you hadn't pulled the Bimmer
all the way forward, and the tires on that Jeep look way larger than
stock.  Might explain your handling difficulties.

You're a lucky SOB, IMO.
