Default Steering returning to center with force

So yet another issue with this new 940 I purchased,

Basically the issue now is with the steering basically fighting you to return to center when turning. And when you let go of the steering wheel mid turn, it doesn't even consider doing it smoothly, it just instantly snaps back forward.

The alignment is perfect in terms of pulling or such like that. I'd almost prefer the car pulling than it fighting me when making any turn.

To clarify this in a way that I can understand (cause I over word things lol):

Basically say when I turn right, the steering wheel would fight me to return to center creating the feeling that the steering wheel is resisting turning making it slightly dangerous to drive even around tight turns. It's controllable but if any other person were to drive my car for the first time, it'd probably scare the crap out of then lol...

Im trying to find a solution that doesn't involved another alignment but it's seeming like that's gonna have to happen unless someone can give me some troubleshooting steps or give me something to check that can possibly cause an issue like this.

Thanks peeps.

Sounds like you have some hydraulic assist going on.

Sorry, you need to replace the rack . . . and do another alignment.

Any weird noises when it's doing this? Our 760 seems to be doing something similar, but I think in that car's case, it may be due to low fluid, since it doesn't seem to do it when you're at normal driving speed, but only at low speed or at a stop. As an example, when you're making a U-turn in a cul de sac, it'll be rather twitchy and noisy.

My 765 had a similar issue (in that it resisted turning the steering wheel at highway speeds) that resolved itself when I installed wider 215/60R15 tires.

In your case I suspect a slipping crankshaft pulley.

Close. Loose belt. Checked when I got home this afternoon. There's a bit too much slack in said belt. Not enough to cause the engine to run hot, but, it's enough to cause the pump to squawk like a hen being knocked up by a rooster when the steering wheel is turned at low speeds or when stationary. So, going to crawl under the car in the evening tom'w and retension the belt.

Just one direction, or both?

Waaaay too much positive caster?
Non-stock wheels with too much offset?
Even horribly mangled suspension can be "tweaked" to go straight.

Here's my muchly over-wordified casterization theory:

With positive caster, when you turn the wheel (right, for example), the inside (right) wheel basically wants to tuck under the car (extreme example), lifting that corner up a bit, while the other (left) wheel lets its corner drop. The act of "jacking" the right corner up helps to center everything when you let go, as there's now more weight on the right wheel, pushing it back up into position. Turn left, the left wheel tucks, gets more weight, and gets pushed back up. Way too much caster (without changing other settings to compensate) can increase the "pushing" force past the tolerable level.

Even with stock settings, if your wheels are offset too much (sticking out of the fenders like the "Kewl" kids), the wheels now have more leverage, and can push up even harder.

Look at tire wear, inners going first says too much toe-out.

Yeah just because it goes straight doesn't mean dick about proper alignment. Could still be way off either way.
