4h

Just out for a snow fun trip in the 4R. I have a stupid steep driveway and trying to get up it in the current conditions was interesting. 4H without center diff locked, no go. Center diff locked, half way. 4L, a little further. 4L with A-Trac selected, no spin, no drama, went up like it was...

According to the little paper in the visor you can do it below 50km/h, or something like that. My previous 4x4 had to roll back a bit whenever disengaging the 4H. The car is a 1993 4Runner with the 2LT

Hey, my 105 1hz makes a burr noise when engage to 4H. working fine in 2H. The burr sound is audible in 3rd gear if i drive faster the sound goes away. what does this sound mean? i changed the oils 5months ago,
