4 x 4 question
Hi all,
I've been hanging around in the background for awhile just reading the odd threads. Finally decided to officially join the group.
My first question is about an F350XLT that I am looking at. It's a 2001, 4x4 with V10 and 111000 miles. I took it out for a test drive yesterday and was happy with it but when I was trying out the 4 wheel drive I noticed something I have never come across before.
While in 4 Hi and turning sharply to the left, the left rear tire was trying to spin. Is there some kind of locker in the rear end of these trucks that only comes on when in 4x4 mode? I tried it in 2wd and it acted normally, like a limited slip but seems like a locked axle when in 4wd.
Am I crazy or is something happening here?
thanks
Neil

barrettwood,
Welcome to FTE.
You sure it wasn't the front end trying to pull it around? If you were turning sharp on a hard surface in 4WD the truck will lurch. Putting it in 4WD has no effect on the rear axle.

Nope, it wasn't the front end. I could see the rear tire slip while I was turning. It was on a paved surface with a bit of gravelly dirt on it. One thing I didn't try was turning to the right to see if it did the same on that side. Will try it again when I go back to see the truck again. Maybe just the surface I was on.

Driving in fwd, there is A binding from front to rear when you turn. The rearend is lighter so the rear wheels are going to slip first. These truck are heavy, driving them on hard ground in fwd and turning is A good way to break something.

Thanks for the replies and welcomes. I don't normally drive on pavement in 4wd but I wanted to try it out to make sure there were at least no funny noises. My old GM has the dragging feeling when turning in 4wd so I expected that at least, just the 1st time I've seen the rear wheels slip.
Mentioning the lighter rear, this truck does not have a box on it either so would probably enhance the reaction. Also there is a problem with the ABS system that they will fix for final sale so may also cause some slippage?
