I about to buy a stacked washer/dryer unit. Can it be laid down in a pickup bed to move, or does it have to stay standing up?

they are not one unit so talk wit a service agent as to how to separate them

No they are erected as a unit, then the house is built around it.

remove the front panel and check the water pump

Yes you can lay the dryer down on its back.

a stack unit is a very risky investment, altho it's understandable if you have limited space. if the hold downs on the washer are rusted out or broken thru you need to have someone weld them for you. That's how we used to do it where I worked but stacks are not usually easily worked on. I'm afraid you will probably have to get an entirely new unit or maybe a used one from a reputable used appl. dealer in your area. Check around, you might get lucky and find one relatively inexpensive

Take one of the screws down to your local hardware and buy new ones and lock washers (with teeth on the inside so clothes won't catch on them).
Good Luck

My twin stacking whirlpool washer/dry. The timer switch kicks on but does not dry clothes kicks off after 5 mins but, clothes still wet.

Thermal fuse

The switches you are referring to are set-reset. These rarely have a fault. Normally the machine control board is the faulty component. How did you determine that these switches are faulty ?

The safest way to access the upper portion of the washer is to remove the dryer. Another method is to remove the "complete" washer front and the control panel. This will give you access to the top of the washer tub.

A small amount is not serious. There is no good way of adding oil to the transmission unless you want to take the top off the transmission.
