vibration 93 escort lx wagon

car vibrates under acceleration above 35 MPH. The more gas you give it the more it vibrates. the heavier the load the more it vibrates, example being going up a steep grade.
if you coast , nothing, smooth as a new car.
So far , axels replaced, front brakes, new rims and tires, rebuilt trans. Everything mentioned needed replacement. Car is properly aligned , the wheels have been rebalanced too. Are we looking at an engine problem??

Any suggestions??

A little more information on the vibration please!!!! Where does it appear to be coming from? What area of the car? When does it begin? When does it stop?

I agree. Feel like the engine is misfiring under load? Any smoke out the tailpipe?

feels like the front end, but everyone including Smith carnes ford in yonkers say the front end is in very good shape. Like i said when stepping on the gas at about 35 MPH and it doenst stop. The only difference is that while cruising at high speed the vibration becomes a more of a rumble. This car doesn't smoke, doesn't use oil, gets 34 MPG's on the highway. Now switching from regular to premium fuel reduces the vibration. Car idles fine, starts fine. The only thing i have noted on the front end is the RS spindle is splattering grease on the rim. It doesn't hum but could this bearing be resisting rotation without making noise? In other words have a rough spot? All the shops i have been to say no noise, then the bearing is OK. I did a voyager not to long ago, did the same thing. When the machine shop presed out the bearing it fell apart. That bearing didn't hum either. Shocked the hell out of everyone.

Mileage on it? Anything on Alldata.com as far as bulletins or recalls?

mileage is 107,000 I don't know about all data.
At my ol job we had these in fleet service, most lasted 250,000 to 375,000 before the engine would blow.
By the way we had the only chevy astro know by GM to have achieved 450,000 miles with the original engine. They wanted to get it back and give us a brand new one but it met its demise when going up against a snow plow before the deal was made.

Places/things to check:

1) Make sure the motor mounts are in good shape.
2) Make sure no heat shields on the exhaust are loose or missing.
3) Make sure the exhaust system hangers are in good shape---vibration can be transmitted otherwise.
4) Make sure the unibody structure is sound. My uncle owed a 1986 Delta 88 that vibrated like that--turned out the used car dealer sold him a car which was repaired poorly and had been welded.
5) Switch the tires front to back. See if the problem subsides. If not, it's not likely wheel and tire related. If it does subside, wheel and tire related.

6) Might be worth a look at those bearings, but I think the obvious is missing here. Has anyone checked the CV axles? If grease is splattering about, first place I'd look is for a bad CV joint.

Has anyone put the car on a lift and tried to simulate the conditions while looking under it (being very careful not to jar the vehicle off the lift of course?

I remember having to spool up a Toyota Supra up on a lift while a coworker watched underneath for a noise. I was probably 30 feet in the air with a stick shift car rowing the gears. Noise only occurred on hard accel. LOL!!

??? who would check this?

CV's are both new, Guess I'll have to pull the spindle and have a new bearing pressed.

Repeatedly. It won't vibrate unless its got to work to overcome resistance . I'm gonna start with the simple stuff, plugs and ignition wires.
