Question for a friend
Happy new year all! Hey guys so this question is for a friend of mine. Now it's not a ford truck but it's a ford sort of recently he had me go with him to go see a 1984 Grand Marquis. The car was flawless had some rust typical for Illinois but nonetheless it was a pretty straight the owner really took care of it and put numerous parts on it last year. How true that is idk. Anyway so the car sat for about six months and surprisingly we jumped and it started right away. The owner said go ahead test drive it see how you guys like it. So we test drove it and immediately we notice that at low speeds under 20 mph the car had a wobble to it after you sped up it went away. So my friend is really tempted to buy it but he asked me what it could be. But I honestly dont know what it could be. The owner said he noticed that but he said it could probably be a caliper hanging up. I was wondering if you guys could give us any ideas or if you guys had experienced this with any car or truck.
Thanks in advance

Since you mentioned he threw a bunch of parts with it, there could be an issue with the brakes. Either incorrect installation or defective parts. I had new rotors that were bad right out of the box.

Regardless I would suspect tires.

I would suspect tires . Since this car sat for an extended period of time the tires may have flat spotted a bit and taken a set. I have the same issue with my summer tires after sitting all winter in the tire rack they have a wobble/vibration at lower speeds for a day so until the flat spots are rounded back out.

If you get the tires off the ground and turn them by hand looking at the tread and see if they jog.
Also look at the bottom edge as you turn the wheels as may also see a bubble.
Last thing is a bent wheel, like the car slid side ways into a curb.
All of them you will feel at a slow speed but not at a higher speed.
Flat spots would bounce the wheels up & down and vibrate the car.
My car trailer flat spots the tires from sitting you can feel in my tow truck. After a few miles it goes away.

I would also say tires but not flat spotting but a cord or 2 coming apart.

And flat spotting can last for a up to 100 Miles depending on the tire. My summer tires generally take about 4 or 5 days to fully lose the flat spots. Radials take a lot longer to get back to round compared to a bias ply and they will wobble once they take a flat spot set due to the cord construction as the strength of the tread cord is not consistent across the tread face. And if parked on dirt the flat spat may not be even contributing to the wobble.
The bent rim/axle is a good suggestion and certainly would do the same thing.
But usually A bent axle act the same but either will be noticeable at hyway speeds also.
