ok, this is a strage case, car sounds wonderfull engine wise. transmition was just rebuilt and shifts like a dream. (just bought this car and frankly i got suckerd) its all great at low speeds but at higher speeds when i give it gas, 40+ MPH it wobbles or feels like im driveing on rail road tracks... im some cases pritty badly. goes away when i just coast however. i take my frount wheels off to find the sway bar linkage to be a rusty spike with some dry rotted robber on it. both sides was completely broke. i replaced those hoping for the best. unfortunately it still wobbles... i can say it handled a lot better! :D. but the steering wheel is off a little.. i can go streaght and the wheel will be turned ~35 degree to the right. what could be causeing the wobbleing? best thing i can think of is wheel barrings, CV shafts, ball joints, kinda coated in 20 inches of snow so not best conditions to work on any car. also. the eletrical in this thing is a nightmare... its been jury rigged to where all the electrical. (include the wipers) on 1 lightswitch... so that's gonna need to be worked on. id like to at least have my heat and wipers separate lol

Have you checked your tie-rod ends for wear? They could also be causing your steering wheel to be off center, and could start wobbling at high speeds as you described.

did a little bit more inspection on the car and found something that might be causing the problems... i found one of the tranny mounts to be fudged. the bare bolt is basically got a good 2+ inches of free movement in what is suppose to be a rubber filled hole lol. so needless to say im getting that fixed. could explain why the tranny needed rebuilt before i bought the car. don't see why it was spotted when the tranny was rebuilt. its one heck of a mess. hopefully that will fix the issue. will post an update once i fix it

replaced tranny mounts and 1 of the 2 engine mounts was not bolted all the way. did all that and unfortunately... it only made the car vibrate less.... that's nice an all. and also will prevent damage down the road. preventive maintenance is always a good thing. but the dang thing still rumbles/wobbles... ill be inspecting the wheel assembly agan tomorrow to try to find the problem.

I have a car that does the same thing - my 87 Omni hatchback. Im pretty sure its the bushing in the lower control arms. There are two in each arm on my omn - the usual cylindrical one on the inner, and a doughnut shaped one where the rear 'leg' of the control arm is attached to the frame.
And loose ball joints will do it too.
You could try swapping tires, front to back, since ANY out of roundness will make the effect of spongy bushings a lot worse. So will a lack of toe-in. I have been told that a damaged bearing assembly at the top of the strut will allow the shaking to happen. So I might need to replace that item.

So far my Escorts dont have that shake - but since they might have it someday, I would be glad to hear what turns out to be the problem.

And of course, check that your tires are balanced, and that they are really round. Having a front wheel jacked up off the ground and spinning it can show up both imbalance and out of round. Remember though, with only one wheel turning, 40 mph on the speedometer means the one wheel is turning the same as it would be at 80mph. !!!
