When I let off the gas pedal and coast there is a rumbling sound comin from what I think is my transmission. My girlfriend describes the sound as someone snorkeling as if the exhaust pipe was under water. If I hold the 4wd shifter up when the sound happens, the sound stops. Can you help me out on this one?

Being that you have a 1998 Toyota Camry, these cars are fuel injected and shouldnt need the gas pedal depressed to feed fuel to your engine. It's possible you may have a dirty fuel pump or dirty injectors. Here are some possible steps (cheapest in $) so follow these in order to spend less money.
- Run some Lucas Fuel System Cleaner (green cap bottle), do two treatments of that in your gas tank and see if that makes a difference. Dirty lines and clogged injectors are caused by cheap gas and or constantly running on Empty thus allowing fuel pump to pick up sediment from bottom of gas tank.
- Sputtering could also be worn spark plugs (too big of a gap) and or faulty spark plug wires or both.
-Timing chain issues usually occur if you hear a constant vibration near the top of the engine.
-Transmission issues would be having trouble putting the car in certain gears, or the transmission stick does not sit in gear properly (slippage).
Just some suggestions that may help with your problem.
If your transmission is an automatic, it sounds like the torque converter is locked. It could besomething as simple as a bad solenoid. You need to get it to a shop and have the computer scanned to see if the solenoids have triggered a trouble code. Also, check your transmission fluid while the engine is hot and running.
Do you have the problem when you turn on the car as well? I had this same problem, turns out the alternator was going bad. A few months later the alternator went. After the alternator was replaced, the problem went away.
I'm thinking it may be the differential (rear end). With that many miles on the vehicle, it would not be uncommon for the u joints or differential to make noise due to increased tolerances from normal wear. I'd look into that. You may be surprized.
If the sound is all the time, no matter what you are doing then it is the Transmission going bad. CV Joints, Wheel bearing will only make the noise when in rotation.. Also remember that this is a front wheel drive car, so it will throw you off thinking it is the wheel bearings or CV joints due to the front wheel drive
