1993 Bonneville
SE L67 swap

The car has always pulled right while coasting, driven straight while cruising, and pulled left while accelerating.
I have new struts and springs up front, didn't help or hurt the problem.
When I did the swap, I replaced the strut mounts (squeaky), the ball joints, rack & pinion and both inner and outer front tie rod ends. All were worn out except one of the inner tie rods, but at that point I may as well fix everything
After the swap I replaced the bottom bushings and washers and bolts on the sub frame mounts.
No noises or clunks, etc...
But still exhibits this behavior. I'm out of ideas of things to check. This makes my LeSabre torque steer seem insignificant. You cant take your hands off the wheel.

check the motor mounts?

Possible that when the subframe mount bolt snapped, the others bent sideways? Would then effectively be sitting sideways a little bit wouldn't it? Torque does funny things like that:)

I replaced all 4 of the rear subframe lower bushings, washers, and bolts and the fronts weren't rusted out like the ones right behind the tires so I think I can rule them out.
I will check the motor mounts later today.

If it helps, it doesn't seem like the pull is in the wheel. At least it doesn't turn the wheel back and forth if I let go and watch it.

A good 4-wheel alignment may do wonders.

Motor mounts are okay. Its done this as long as we've had it. We had it aligned once before when we replaced the one ball joint and tie rod end, and it still did it after. I figured replacing everything while it was already apart should fix the problem... It's going in Wednesday for an alignment and I wanted it to be the last time for a little while at least. I'll have the shop check everything out on the lift, he may spot something I missed.
