I think I'm going to be going down the old $$$ rabbit hole here, but I figured I'd try to get some ideas first.
My Dart shakes pretty badly on the freeway. It's almost not noticeable at 65, and by 70 the dash and wheel are shaking up and down all over the place. Any faster and it keeps shaking. I sometimes feel it in the seat, but it's mostly in the wheel/dash.
I've had two sets of tires/rims on it, and the current set is new from Wheel Vintique with new tires. They were balanced by the local Discount Tire, and my other old cars don't shake like this. It seems to shake about the same with both sets of tires. The lower ball joints are new, the tie rods are tight, the idler arm is new, but everything else is old. Everything feels tight except for I recently noticed a bit of play in the left upper ball joint, not a lot. It has a set of the white KYB shocks that came with the car.
I've driven cars with old suspension before, and they don't generally shake like this. The front end doesn't really clunk or wander (more than a normal old car). I understand new bushings and stuff are always a good idea, but I don't want to spend time and money on things that aren't going to fix the problem either.
One last thing: I did have the local driveshaft shop replace my trunnion boot and rebalance the driveshaft, but it doesn't feel like a driveline vibration to me, especially considering that it's in the wheel.
Well, let me know if you have any idea where to start here. Thanks!
