When going over bumps it moves all over the road. Front end goes all over the road. at 60 mph the car shakes an moderate oil leak.

I would remove one end of the steering stabilizer (if you have one) which looks like a shock absorber laying sideways attached to the steering linkage and pull and push on it.It should be stiff to move.
Also have the tires dynamically balanced on a motorized name brand wheel balancer.Next have the front end alignment checked with the normal load you carry in it.Not enough caster in the alignment can cause a shake/wobble easily.

Have you cked the bushing lower and upper

Could be a wheel, tire, or axle shaft.
You could rotate the tires front to back and see if the vibration moves.
If it does the problem is one of the tires or wheels.
If it stays in the front, its probably one of the axle shafts. It could also be a hub bearing or something loose in the suspension. But a loose suspension part would normally show up when you hit a bump rather than on a smooth road.

I would check the front struts. They could be worn out (you didn't give mileage), or simply loose. I would recommend you either check them or have them checked as it could be minor or it could cause damage beyond the problem. One way to have them checked is to take it to someone that does front end alignments. No reputable shop would align a car with defective parts as the alignment wouldn't last. Sorry I couldn't help more, but a test drive would be required.

What you have going on there is commonly called "death wobble". It's not as bad as it seems.
Most often it's caused by either worn ball joints or track bar ends or mounts. It can also be caused by items such as tires that aren't terribly worn but worn enough so that they don't have enough weight to remain steady when they flex, improperly torqued wheels or cumulative wear in several of the front end components that add up to excessive play. Item most often blamed incorrectly is the stabilizer (sideways shock on suspension) That can fail after excessive repeated shaking but is never the cause of that. Make sure that the steering box is solidly attached to the frame and in extreme cases, have an alignment shop add a couple of degrees of extra caster to the alignment specifications.

Vibration from about 40-60 mph is usually attributed to wheel balancing, but the onset when you hit a bump seems to indicate play in the steering linkages (tie rods etc) or suspension members and stabiliser bar rubbers but you had that all checked out, that brings us back to the wheel balancing.

Could be a tire out of round, or even a bad strut. Bounce the front end, if it's spring like, the strut (s) may be bad. Look for leaking of oil from them, that is a sign of a bad strut.

Pitman arm and tie rod ends and bail joints.The three main causes of front end shake after hitting a bump.There's so much slop that when you hit a bump it shakes violently from one end of the slop to the other.Very dangerous!You need to get this fixed now!
Get someone to turn the steering wheel while holding onto a front wheel and just watch for stuff that moves.Turn left and right and you'll see what's the worst for wear.The connections at the steering box arm(Pitman) and at the wheels(Tie rods) will be what moves the worst.Hope this helps?Autozone has a kit for the pitman for $100,probably be $600 at a shop.

I had a truck at work that did the same thing. Only if you hit a pothole. In my case the front tires were way out of balance. Hope it's something that simple.

Front shocks are week
