the only thing i can see that would damage anything is 2wd -> spin tires -> keep spinning / switch to 4Hi -> kaboom...

(dont ask me how i know )

Can you double check your statement please about boat ramps? What the heck do you think these are intended for? If the ramp isn't slippery i.e. wet or e.g that boats are dry when they are pulled out of the water then I guess you are correct that the OP should have used 2WD but again I stand behind my statement that the ramp was slippery and that this is what 4WD is for. I always try 2WD but usually need 4WD with the weight of the boat, the friction pulling the boat from water, algae on the ramp etc.

In WI we have ramps made from blacktop, concrete, railroad ties, sand, stone. Not all of these give optimal traction ever and are often slippery when they do not look wet. So please try and understand the difference between DRY pavement and everything else. Most issues with 4WD are not even caused by moving straight they are the binding when trying to turn. 4WD is designed to move forward with out turning (unless conditions allow it i.e. slippery) and should have no problem going from slip to grip and back again. It's when the inner and outer wheels have to turn at different speeds but can't that you run into problems. Sorry I do know how 4WD works and understand the manual as most of us do on this forum. The OP needs to find an honest dealer on this one.

Beyond reading the manual please understand how things work before calling any more people out!

and thats exactly how i could tell i was in 4x4, first turn, wtf? oh yeah, oops...
lots of straight roads around here

Oh I know, slow going in 4wd. The spinning got him I'm sure.

Sorry I didn't know the warranty information isn't in the manual. Maybe someone can check that but as far as my manual for a 2012 goes,,, no where does it say,,, not intended as it does in the 2010. I also disagree with the sudden grip from spin did it as I have been in ice with my 4x4 spinning and once it hits a wet / no ice, no snow patch that wheel is grabbing! So if you say that I will snap the transfer case mount when this happens,,,, then I think we better start looking for a better stronger mount! I also think that pulling out of a spot be it dry, wet or whatever isn't what the manual is saying I think it is leaning towards Don't drive the truck in 4x4 while on dry pavement. However my manual says it might wear out the tires and make some noise... it doesn't say it will rip the mount right out of the truck.

Ohh what fun!

I also know how 4wd drive works! You need to check your statement in how 4wd works!

You are correct on turning but going straight the front and rear axles are also moving at the same speed mechanically tied together! That is why if you regear, you need to regear front AND rear because then they would both be trying to spin at different speeds and bind the transfer case.

So going from a slip and grip situation would be horrible as it has shown here.

I will still disagree that when inventors came up with 4wd they were thinking of pulling their boat up a ramp. Can it be used? Yes it can as long as its used correctly. If the OP wanted to use it, 4lo would have been a better choice.

Rescue,,, Do you have any idea why they say not too?? Honestly? not being an *** just wonder what your opinion is on this? I have known they state wet or snow but think about this statement. we have traction control so if a tire spins it puts the load to a non spinning tire... so the only reason I see is when its in 4x4 and you turn the wheels the wet, ice or snow allows the tire to slip! Other than that it doesn't make any sense to me.

Visit any boat launch around here in the summer, especially when the Salmon are running and you wont ever see a dry ramp ever. Back when I launched boats with my ranger it needed 4x4 almost every time or it would get dragged in the lake. Ramps get slick, really slick. Driving in a straight line in 4x4 on slick pavement like you would launching or landing a boat should not harm your drive train. Making turns in 4x4 on DRY pavement or other high traction surfaces are what causes damage.

You must be a very literal person.

You cannot put everything in the manual regarding warranty. It also doesn't say in mine that I can't jump my truck but if I did and screwed something up should it be warrantied?

Your wheel spin scenario is different, are you talking front! If you are, it's open diff and even though you ink it's gripping its not getting full power.

You guys really buy into that marketing on "built Ford tough" huh? I've been in several better built trucks and have broken parts OFFROAD. Things will give and weak links will always surface and in is case it's the TC mount!

Also, if he was spinning all his wheels a good amount and then his front gripped dry then that would send one heck of a shock load to the TC which will take the most of the damage.

I'm not venting!! I'm just letting people know to be careful pulling boat out of a slippery ramp in 4wd. It was Labor Day when it happened so you can only imagine the traffic at the ramp plus the broken out drive that spilled oil on it.
