I was out running my genesis in the parking lot yesterday. It was fine if I slowly accelerated to medium speed, but if I went full throttle it would begin to pull to the left side almost fully turning. Does anyone know why it's doing this? It's hard to control the truck when it's pulling hard to one side and when I try to adjust it, it pulls right back.

Its torques steer.

The by-product of having a big powerful engine mounted transversely.

Not much you can do about it really.[&o]
You'll get used to it.

If you care to read this thread, it has links to 2 other threads that find solutions to steering problems. In one case it was camber and toe in, and in another case it was torque steer.

Hope that helps.

thanks dustin, I'll try the camber & toe-in solution.

Actually, Dustin Toe-in does effect torque steer, help counter it. Camber not as much.


First torque steer is produced from High output engines sending alot of power to an "open"(unlocked) Differential. The action of a diff, allows one wheel to spin faster on the outside wheel of a turn. This "Action" can also occur under extreme loads-causing one wheel to spin faster, Actually the diff is loading one wheel more that the other. This is not regularly seen in smaller less powerful cars/trucks, but the Genesis/Nemesis NX76 has enough power to reveal this problem. When you apply full throttle suddenly the front wheels "want' to lift(wheelies) with the lesser load on the front wheels, so the rear wheels with the torque steer effect tends to cause the truck to "turn" Or Pull to one side. If the front wheels that are toed-in or out will want to turn into the direction of the toe and torque steer. Also with the front wheels unloaded and the toe-in the rear wheels with extreme power will have an easier time turning or torque steering.

Understanding this,,the solution becomes obvious, Adjust the front toe-in to Zero and the rear toe-in 2-3 degrees in. Also, you could fill the rear diff with heavier fluid to help the diff distribute the load better or lock it all together. The problem with locking it is it is harder on parts and steering on loose tracks cause understeer issues or "pushing" so I believe heavier fluid WITH Zero Toe-in is a better choice. It helped me alot!!

Remember--this is only an aid and does not counter Torque Steer completely. A Locked Rear Diff Will Cure It Completely!! I Have Tested It To Prove It!!!

gotta love this board....learn something new everyday. Next time I break down the truck, I'll try adding a heavy weight oil in the rear diff and see how it handles. The toe-in setting dogman added can be done soon...just need to get some guages. Is there a setup sheet for the Genesis/Nemesis flying around anyplace?

Cen has some on their website.....
