Bought the kit for my 2002 f350 last July. Delivery was quick, installation was easy but the driver side mounted hub stopped turning on after a few months yesterday. My truck is never in mud or deep water. I only have to switch on the 4x4 drive every now and then when I put my boat backwards on the steel boat ramp. I would not buy this item again. I did not see any warranty information. I ordered another brand from Amazon with 5 stars and guarantee.
