Tandem placement and turning radius

I'm glad I worked for a company that knows what it's doing. Any trainer asleep. While his trainee is behind the wheel. Would be fired.

But at least it explains why you don't have the knowledge.

 

If these trucking companies gave some kind of incentive to stick around after school, they wouldn’t have such a turn over rate.

If you could get a better deal after training and school with another company, would you stick around?

 

Topping out the suspension basically means all 4 corners of your drives are in the same plane (no articulation) . Unless you're on perfectly flat pavement, one corner will have significantly less weight on it than the others (and therefore much less tire to ground traction,) and will spin quite easily.

I have an overlift system on my carhauler, and I usually lock the power divider at the same time I overlift, especially if I'm pulling out into traffic and will be getting into the throttle. For the exact same reason, with the suspension near the top of its travel, it's easy for one corner to top out and lose full contact with the ground.

 

Because your rear axle is mostly off the ground.

Next time you drop a 40k plus load, put the landing gear down until it just touches the ground, then pull out and stop as soon as the 5th wheel clears the trailer. If you get out of yhe truck quickly you will be able to spin the rear tire freely. Over the next minute you can watch the tractor suspension deflate and the 5th wheel lower in relation to the trailer.

As a side note, if the traction control is engaging on dry pavement, it's a sign you should stop and let the air bags settle. You are risking differential damage by trying to force it through.
