When an unpowered front tire hits a puddle or slush, its going to slow down and hydroplane. If its powered its going to spin through the puddle or slush and pull you through safely. 4x4 (real lock) is going to pull you through, just have to remember to give it a little gas. Throwing it into 4x4 in any slippery or mixed conditions will help some, much safer than using 2wd and waiting till you wish you had 4x4. I'm perhaps not an expert, but I've driven near 300,000 miles in adverse conditions.
Front wheel drives handle hydroplane conditions better than RWD for the same reason.
An open front diff, like all rams....if one tire starts to spin, it is gonna get all the power & keep spinning. Not sure if the traction control will help much on the front axle....I know it is annoying on the rear axle if you need to spin the tires.
All I am saying, is in a 2wd, the speed of the front tire spinning is directly related to traction...if there is no traction it stops spinning and just slides, if there is traction, it spins at the speed the vehicle is moving, no faster, no slower.
If in 4wd, and a front tire loses traction, it is no longer spinning in relation to the traction available, but in relation to the engine speed, and that can be faster than it should or slower than it should, and either way, you have no traction...and in that case, it's better to let off the gas to let it regain traction, then get back on slowly.
Not claiming to be no expert here either, but I've driven more than a few thousand, and most of it was in 2wd...only using 4wd when needed. Whether it is mud or snow.
1 thing I have noticed in my Ram, if a front tire starts spinning in snow/ice, and you give it gas, it keeps spinning...let off the gas, it stops.
