crossover steering and wandering at high speed

[zachandandy]

The throttle steering is amplified by shorter wheel base. In a samurai or wrangler it gets really sketchy.

I understand that when the tires break loose, but under normal light driving conditions, I don't see why it'd throw me around on the road.
Like, under normal people acceleration or when I let off the gas, I have to be ready to compensate at the steering wheel or I'll be in the ditch or through the meridian. I've never had this problem with any of my other 5 or 6 XJ's. It started sometime after either the crossover steering, or the lockers as far as I remember.

I thought for the longest time that it was rear steer caused by dog-tailing due to the front axle moving left when the front end comes up (due to track bar) causing me to go left (as the rear axle is then a bit right of the front) and vice versa, but my track bar is pretty near flat and I've seen much sillyer track bar angles on XJ's that track just fine.
