If its only while your moving then its going to be your wheel bearings.

SOURCE: Oil pressure is fine. Oiling only to the pass side valve train.

The 3.1/3.4 engines are built the same way. The oil goes through the cam bearings then to the lifters, then the push rods to the rocker arms. The last engine I seen that had a weird problem had the cam bearings spun. Unfortunately there is no easy way to check for this problem short of disassembling the engine.

The other possibility would be bad lifters but loosing half of the engine lifters wouldn't be possible. Sometimes the pushrods wear on the contact areas also but not usually half an engine.

This isn't going to be easy, Good luck.

SOURCE: Garage told me problem could be the drive train.

Drive train is Engine all the way to the axle/axles that drive the car, hence the term drive train.

how do I take the engine apart to replace the gears in the engine

SOURCE: Vibration in the drive train at 40 mph in my 1993 Ford 150

I would check the driveshaft universal joints and the play in the yolk joints where the driveshaft exits the transmission and where it enters the differential.
It could be the preliminary vibration caused by the deterioration in a universal joint, forewarning you that it's on the way out. Good Luck Vern
