ORD Shakle Flip Seasickness

[NV_K5]

What is really fun, is that when you try to correct, you shift the weight the other way, and the truck goes into oversteer in the other direction. Next thing you know you are sawing the wheel back and forth like a madman trying to go straight while the rear end is all over the place trying to pass you on both sides.

sounds like you've ridden in my Jimmy.

Rear steer is caused by the axle moving forward and backward with flex. As you turn right for example, weight is transfered from the right to the left side of the truck. More weight on the left causes the spring to flatten and move the axle backward toward the shackle while less weight on the right causes the spring to arch and move the axle forward away from the shackle. The net effect is the axle is no longer perpendicular to the frame and instead is trying to help the truck turn even tighter = oversteer.

Got it, good explanation. Sounds like something good shocks would take care of.

Is that flange after the muffler for removing the tailpipe on the more difficult trails?

No, I put in flanged connections throughout the system so it can be easily removed if need be. I can pull off the entire system up to the headers in less than 10 minutes.

Oh I see. I guess I cheated. I have duals that dump infront of the rear axle. I could pull it out in less than 10min too.

But I can drive mine with the rear window down
