4x4 high pitch
Used 4 hi the other day for the first time in a while. All engaged well and then disengaged when I turned the knob off. After I pulled back out onto the road and got up to speed 35ish, I noticed a high pitched sound, almost like a squeal coming from up front. i couldnt tell what side. After about 5 miles it went away. Any ideas? Should I engage 4x4 more often. My Ranger I had used to do the same thing and I think it ended up being something with the vaccum system so I wonder if thats the same with this?
