4-High comes to stop and seems REAL tight..
4-High comes to stop and seems REAL tight..
This afternoon I was driving through a park that had some snow and ice. I put my truck in 4X4 high and had the overdrive turned off. I turned into a parking lot and all I had to do was take my foot off the gas and the truck came to a stop. When I pushed on the gas it almost seemed like the parking brake ws engaged. I turned off the overdrive back on and it seemed to help a little. I turned it back on while moving at 20-25 MPH and it didn't seem to bog it down or slow it down.
This is a 2001 F-150, 5.4L, 4X4 Off-Road. I don't ever remember my 4.6 doing this. Is this normal do to Overdrive being turn off or is there something going on here that I need to be concerned with?
Thanks in Advance and sorry for posting this in different forums. Didn't know which would be best.

Where you in the snow/ice when you let your foot off the gas? You will have more resistance against the front tires in the snow. Plus the extra resistance in the drive train for being in 4x4.
Try it engaged in 4x4 on harder ground (within reason of course), and see if you have the same resistance.

Like the other post said, the question that has to be answered is whether there was snow and ice in the parking lot when you turned in. If it was just normal pavement, the 4x4 was working just fine and the problem was operator error. It's not so bad when you come off-road and don't immediately disengage the 4x4, as long as you are not turning. The biggest boo-boo I've seen someone make is come roaring off a trail and nailing a turn onto pavement with the 4x4 still engaged. The front wheels MUST spin at a different RPM than the back when part-time 4x4 is engaged, and gravel, sand, mud etc. allows this to happen. It's very hard for tires to spin on dry pavement, so all that force build up gets transferred back to the drivetrain components. Good way to cost your self serious money. The example I cited, that individual ended up doing over $2,000 worth of damage to the transfer case and front driveshaft.
