I mean given my track record I’m not surprised:(
Well today I got my exhaust ran and my alignment done. Took quick loop around block (first drive ever in this bronco) and immediately something ain’t right. Let the mechanic drive and he said it’s torque and memory steering..

It pulls under acceleration an when you make a turn it fights you. He said a ball joint could be torqued to tight but time had expired and we couldn’t play anymore

I was hoping the video showed something about what was happening.

Pulls under acceleration could be bump steer, or bad leaf spring bushings.

Fights you in a turn, that doesn't really make much sense. Most people want the steering to return to center. Track straight down the road.
A tight ball joint would be more of a wander. It "locks" at an angle and takes a bit of force to re-aim the wheels. It isn't smooth and self centering. More of a fight to drive straight.

The alignment man points the wheels in the correct direction. That doesn't mean squat about getting the lift parts to work together. That's not part of an alignment, that is part of the build process. The two are not related.

I'm going with the group, "memory steering" is a new one to me too.

I think of a dragging caliper whenever I hear pulling under acceleration. Anything when you get off the gas?

New to me as well. My pappy,amongst other things was an alignment specialists and I never heard those terms.

Memory Steer: A vehicle's steering wheel is supposed to return to within 30º to 60º of center after completing a turn. If the wheel does not return as specified, the vehicle is suffering from memory steer. Typically binding parts cause this condition. Inspect upper strut mounts and bearings on front wheel drive vehicles. A binding gear or universal joint/flexible coupling will result in poor steering wheel return to center. Check the adjustment of the steering sector/worm gear.

Torque Steer: Torque steer occurs in FWD vehicles when the vehicle pulls to one side during hard acceleration. This is due to uneven axle shaft lengths. They pull to the side with the shortest axle. Some vehicle manufacturers have created vehicles with shafts of equal length to compensate for this phenomenon. Different tread patterns or different size tires also result in torque steer.

That sounds like a lack of caster. Which is common on lifted Broncos. Fixable, but may be beyond what the alignment shop is wanting (or capable) of doing. Ranges from bushing swaps to cutting and welding.

agreed, lack of castor for the return to center problem. Pulling under acceleration is common if you have a locker in the rear end.

Front was in neutral, it has a 3” lift, no lockers front or rear. It’s “possible” we didn’t get the correct bushings for the lift. I told my dad it looked like it was lifted when we got it but he thought it was factory.

Measure from the top of the front axle tube to the bottom of the frame rail directly above it. Stock is a little over 7".

If it isn't this, then it's something else. It's never ending that's for sure. I've come to the conclusion that my boys will eventually get my "Bertha" running great with all the creature comforts needed to make it a "safer and dependable" rig.

Currently on my list of to do:
1. New brakes (might finally do disc conversion)
2. New headers (I've had an exhaust leak since 'Nam)
3. Fuel injection (when...maybe when the boys are finally adults and living on their own)
4. Body panels (where do I start)

New Balljoints can cause "memory steer" too. New heavy duty balljoints are stiff until they wear in.
