Well whatever the change, I can now take my hand off the wheel on the highway. I appreciate all the input.

I offered / she declined. Been a while since we've owned a stick shift.

Remember column shift cars? Always a good time.

Made it home from Davis. As the smooth highways of Northern California rolled by and we returned to the wagon wheel ruts of Oregon's studded tire roads, so to the wander returned. Oh well. Not terrible. Just there.

My car wanders on our lovely rutted roads, to an extent as well. Hope Davis was all you hoped it to be?

I remember when I was a kid and we borrowed a neighbor's car. Mom climbed behind the wheel, looked at the column and said: "This should be interesting." Like riding a bike. She did great.

A small price to pay for cat-like handling, eh?

Bump! Because i have the same issue and it is annoying.

Stock suspension minus -1.5coil off upfront, balljoints are tight, steering rack is tight, bushings are new or good condition. But when I'm holding the steering wheel in one position on a little wavy road the car starts to wander and i need to "countersteer". Happened on completely smooth highway too and was a bit weird.

Car has working PS, PS balljoints, and also i moved the control arms 6mm forward to gain a little bit more caster. It tracks straight, toe is somewhat good but I did not take the car to an alignment yet.

It sort of feels like the rear end just steers the car with the big rubber trailing arm bushings. Want to go spherical there, do you guys think it will improve the situation?

How much air pressure are you running in your tires? What's size tires and rims? My 235/45/18 kumho v720 grab every ripple and rut in the road, but it's much worse with too much air in the tires, they're only drivable at 28 psi or less. My 195/65/15 also make the car almost comfortable to ride in, but also at around 28psi. I'm on cut springs with Koni s so the ride is very stiff regardless.

LOL, I learned to drive on my parents 75 Ford Grenada with a three on the tree.

Interesting!
I'm running stock GT rims with 195/60r14 tyres at 2,5bar.

Dropped tire pressures to recommended values, 1,8bar front, 1,9bar rear and it seems this weird issue is improved! Will play with pressures more to see if it really cured the wandering.

Interesting read:

https://www.tirerack.com/tires/tiret....jsp?techid=47

"Tires have the most direct influence on tramlining because..."

The tires I took off were unsafe, so I don't have a good back to back comparison from the old tires to the new tires. I would be curious to swap on a different set of wheels / tires and see what changes. If anything.

I put wider tires (215's I think) on a '76 Celica once with no problems. On a '77 Z28 the car went to heck with 245's. But at least I looked cool.

Poly seems to help. Feels more "planted." Start with the basics (like replacing soft bushings). Imagine that.

Got some used poly torque arms for the rear. Then align the wheels again.

Getting closer...

That middle pic shows a worn, tired bush to me. Good call on going through with it.

Yep. Both alignment shops said everything was tight. But at 300k I was only kidding myself.

OP.... Wheels with different offset from stock will make for dramatic results.

The car was designed to be run with a weenie 185-14 tire.

Using a tire of 205 width with correct offset wheels that is taller then stock will make a longer contact patch. You may be shocked at how much more grip is there with that shape of contact patch.

Nothing to see here...

Oddly, the driver's side was chewed up while the passenger side was solid.
