The teeth and bearings on the 2nd gear and 2nd gear shaft are worn, when putting it into 4x4 it puts a heavier load on the shaft that quiets the bearings and forces the gears tighter together.

4wd is only for, offroad, and ice on pavement only

and causes damage

4wd means front axle is locked, if not,that means you are not in 4wd . (makes since right?)
with auto or manual front locking hubs.

I have a Nissan 3.0 16V 4x4 offroad. the front hubs and differential makes a tapping and grinding loud sound even when 4x4 is disengaged.


thats because it runs on front wheel drive in 2d if iam not mistaken,best advice i can give is to ask a local man to have a drive and give an opinion as from afar i have no idea even for a guess without a drive

My 1996 GMC Yukon 4x4 transmission will only drive in 1st and 2nd


It will take off from a stop in overdrive but as soon as it shifts into 3rd at about 30 miles per hour it jumps into neutral? If yes, you have a burnt 3/4 clutch. The transmission will need rebulit. Cost of about 1600 dollars.

Is it starting out in 2nd. too? If so you may have a blown fuse or you tore some wires off. If the trany loses it's electrics it will go into the limp home mode. It will only have 2nd. and reverse. GM vehicles do the same thing.

I have a 2001 Olds Intrigue, I replaced the starter and it still grinds. What could this be? Single Lady


Did you replace the starter yourself or did someone else do it? Sounds to me that someone forgot to put the shimms back in, they go between the starter and the engine block where it bolts up. Without the shimms the starter will be to close and the teeth on starter drive will not engage teeth on flywheel.

Your trouble is most likely not in the transfer case but in the front differential engagement solenoid.

Intermittant grinding noise in front of vehicle


sounds like a bearing is going bad. sometimes the bearing will have manufacture defects causing the metal balls in the bearing to grind and break down.
