I somewhat disagree. Torque steer in fwd vehicles with unequal axle length is caused by axle windup, mostly. The longer axle winds up more than the shorter one. Thus the car pulls to the long axle side under accel, and back to the short side on decel.

Open axle 4wd or 2wd vehicles spin one wheel more than others due to chassis twisting and consequent wheel unloading due to engine torque, most pronounce with a longtitudinal engine setup. Ever watch a heavily loaded semi tractor start off uphill? Those things twist the chassis over 6", easy. Really nasty looking stuff. I once watched a D9 Cat 'dozer trying to pull out another stuck in the mud D9 twist more than that when it hooked up the tracks real well.

BTW, I would also check the idler arm wear and tie rod ends and ball joints. Any of these can cause your problem.
