Torque Steer?

I hope this is the right area for this... Has anyone experienced torque steer while towing?
Driving solo is without any noticeable torque steer, even under full throttle, but anything near half throttle or above while towing produces torque steer to the right. I'm used to it now but if I were to let go of the wheel I'd drop onto the shoulder within 5 seconds. I'm wondering if anyone else has been experiencing this.

I've only heard of Torque steer with a front wheel drive vehicle. Engine torque tends to make the car pull to one side when under heavy acceleration. Never heard of torque steer with a rear wheel drive vehicle. Besides, I bet you have some form of posi-traction in your truck.

Sounds like the OP has an alignment problem or loose bolts in the suspension somewhere. I've never had it on any vehicle except the front wheel drive cars and the very fast non stock '67 Camaro I had.

I have turned wrenches for over 30 years and I too have never experienced torque steer with a rear wheel drive. The truck had 7 miles on it when we purchased it so I may contact the dealer. This one has me stumped.

Two things that can cause that situation are, a broken center bolt on rear spring or broken or damaged right axle and limited slip differential.

I have a 2007 2wd 2500HD w/ a long bed and I have the same towing or not. I had it in the dealer a couple of times and had an alignment done and I even had the guy drive the truck with me. Chevy never could get the pull to the right completely out of it with an alignment. It's not as bad with the new tires I installed a couple of years ago but it's still there.

It was even suggested by another alignment shop that chevy has a right hand bias built into the alignment. I don't know if I believe them but it briefs well. Reduces head on collisions????????????

I'm like you I have gotten used to it. Just don't take your hands off the wheel.

If all checks out as ok in suspension, steering, and drive line a four wheel thrust angle alignment check could reveal something. Need a shop that has the equipment and alignment tech that knows his stuff.

I had a long response typed out but the site timed out and I have to cool off before responding again.

Thanks to everyone for responding, I study each response and try to apply the information given.

Happy Thanksgiving everyone!

Ok.... had the Excel hooked up today and drove about 20 miles. While I had it, I decided to try to figure out why it was pulling to the right. I made an interesting discovery and it's leading me to believe that the pulling may actually be in the auto_slide 5th wheel hitch.

My first hard throttle was from a stop sign heading straight down the road - no pulling! I thought, great, it's gonna be even harder to figure out if it doesn't to it all the time. The second and third acceleration had it pulling to the right. Well, I had a few miles to think about it so when I exited the highway I pulled away from the stop sign, straightened out the rig and stopped. I then accelerated straight down the road and... no pull. Then I started thinking, I wonder if I can get it to pull left. Next stop sign was a left turn so I accelerated from the stop sign in a left turn and the darn thing pulled left.

I'm wondering if the auto-slide hitch is binding "just enough" to keep the rig from completely straightening out until the throttle is released causing the pull.

Seems like you are on the right track... If it only pulls left or right with the trailer,,, look there,,,,, not the truck... Let us know what you find.

Sorry for being absent, life got a bit crazy.
It's been a long road in the 8 months since installing the Demco 18k autoslide. After personally repairing some factory defects with misguided info from the factory we finally thought we were on the easy road with our new Demco. Our relationship with Demco was good right up to the end when we were so unhappy with the unit that we requested another unit, that's when the company turned cold on us. Now with this issue, it'll be interesting to see how we're treated.
