Was out on the ice yesterday and had the truck in 4 wheel drive. When I turned right or left it sounded like a tire was rubbing on a mud flap. I know I do not have that problem and the gear oil is full. (I will be changing it soon though). Anyone have any thooughts? This is the first time I have heard the noise. Could I have done something when the wheel bearing housings were replaced. No noise in 2 wheel or going straight.

Thanks

 

Was it a very sharp 90 degree turn and/or a turn onto a drier road?

 

not 90 degree, not dry pavement and only noticed it at 5mph or less??

 

In four drive, the tires spin at the same speed in a straight line. But when you turn, the tires in the back spin at the same speed but the tires in the front dont spin all the way over causing the tires to slip a little. I think they usually slip in the back but I'm not exact on that. The inside turning tire has to spin less than the outside turning tire in order to make a u turn. Thats about the best I can describe this. Hammer can probably do better though.

 

it's physics really, when you do a u turn the front tires don't complete a revolution in the same time or distance that they would if they were straight..therefore the back tires just follow where the front tires guide them to go so the back tires still complete a revolution at their normal speed depending on how fast you are going. I have had that problem before too because the back tires can't rotate as slow as the front when you do a turn (depending on how sharp the turn is too).
