Trailer sway can be seriously scary...

Ulf - 22 Sep 2007 01:50 GMT 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.

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...

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

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...

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.

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.

DYM - 27 Sep 2007 22:16 GMT 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.

Ulf - 29 Sep 2007 14:18 GMT > Ulf, > [quoted text clipped - 3 lines] > 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...

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.
