Under what conditions do you want to use 4wd lo? I know very little but was reading how you can pretty easily damage driveline parts.....I put my truck in 4wd lo and drove up a paved road for about 2 miles total,15mph max.....just wanted to make sure everything was working correctly as I've had truck for few monthes and only checked it at time of purchase.I noticed the rearwheel can skip when making a slow turn? I only made two turns,was mostly straight driving...I've since read it's not advisable to use 4wd lo like this? Everything seemed to work as it should,and as I said I took it real easy.....Any advice? Thanks much!!
