[QUOTE="Jackson Ellis, post: 1010204, member: 70795"] What Yardsale was getting at with tire size is whether all of your tires are the same size. Bucking in a 4X4 system like yours can come from the tires turning at different speeds. This is why it bucks if you turn on a hard surface while in 4X4; the inside tires are going slower than the outside tires. That's fine if you're on snow, dirt, mud...etc. the tires will just spin, but it's not on dry pavement where the traction is too good. So if your front and rear tires are of different sizes, then the axle with the smaller set will spin faster, and the 4X4 system will return the favor by bucking. It can damage your truck. If you have chains, cables, or even a large difference in air pressure, you can get the same effect. [/QUOTE]
