94 Bronco rumble during accelaration at higher spe


I'm experiencing a problem with my 94 bronco in that when on the highway (only) when I either accelerate to get onto the highway, or increase speed on the highway, the bronco vibrates like I was driving over a continuous rumble strip. When I let off of the gas, the rumble immediately disappears.

I don't believe my tranny is slipping because although this rumble occurs, I feel the truck picking up speed.

I've tried disengaging the OD but that didn't help. My most recent work that I've done on the truck was to replace the Mass Air Flow sensor, and replaced the upper and lower ball joints.

After I replaced my ball joints, put new tires on the truck, but never got it aligned. Now my right front tire is bald on the outside, but I got it aligned, but again need a new tire.

Researching this, I'm reading boards that these are the many solution to this patricular problem:

1. Loose connection at the MAF sensor.
2. Bad plug/wire causing misfires at higher RPMs.
3. Exhause pipe resonating at
4. Loose rivits on the torque converter (Ford issue)
5. Added incorrect type of trans fluid. Changed.
6. Add anti-shutter fluid. (I don't know the product used here)

Any ideas?
