Rear wheel hop

So I took my new to me 06 out today in some soft sand. When in two wheel drive at a crawl she does fine. But, if the sand gets too soft and the tires start spinning the WHOLE truck shakes violently and you can actually watch the manual shifter jerk back and forth. From what I have gathered there was a TSB for the leaf springs. Is this what is causing my issue? It feels like the damn rear axle is about to rip out.

 

I have actually experienced this. But only in loose sand. Never anywheres else. I also have lift blocks in the rear so I blamed them. Its also like you said only when traction is getting lost. Glad to have 4H

 

Manual or auto for you?

 

Makes sense. So I am assuming that a truck with independent suspension in the rear would not suffer from this as much. But of course leafs are better for hauling.

 

I have an auto.

 

Try turning off the electronic traction control if you're looking to spin the back wheels (usually requires holding down the VSC button for a few seconds and won't reset until you turn the engine off and restart).

The truck going nuts may have been the computer trying to get the rears to catch and stop spinning faster than the fronts. Not sure how the Toyota software works, but in other cars with similar systems it can be manipulating/overriding many systems including spark timing, AFR, and brakes; the TC program in my RX8 nearly rocked the car out of the dyno rollers at the smog shop before I remembered to tell the tester how to deactivate it.

 

I don't even have VSC

 

Neither me. I think its just the way it works out on our trucks. I have never experienced it anywheres else. Mud or rocks, wet road, cement, even doing burnouts I haven't recreated the hop. I just chalk it up to the right set of circumstances.

 

^^^ I agree. I had a Dodge Dakota before this truck and it did it slightly, but not as violent as the Taco. I am adding that to the fact that the Taco is lighter in the rear and the suspension differences. That dodge was a beast and could just power through the hop with the power it made (v8). But all in all it still can't beat the new truck
