Do you have different gearing in the front than in the rear? different size tires front and rear? This could cause the drive shaft to spin at different speeds which will prevent you from going into 4wheel on the fly. Also do you have locking hubs or hub flanges? One of you locking hubs could be f@cked.

Just so you know, you can't shift on the fly into 4lo.

Wasnt shift on the fly-4wd only in auto hubbed vehicles?

Cant really call a truck on the fly-4wd when the hubs dont lock.

If you have your hubs locked already you can shift on the fly. If they arent then it will just grind like crazy.

what would be the point of shift on the fly if you had to get out and lock in the hubs

OP you have been doing the shift on the fly to much and it has gotten worn out.

It's like these. Most Tacos came with ADD. With ADD the diff is spinning all the time because the driver side axle is aways engaged and turning. When you shift the front driveshat and ADD the diff is spinning so everything can mesh up. However, if you have manual hubs and the hubs are not locked the diff is just sitting there static.

If your driving during the winter and you know there is a possability for snow along the way, you lock your hubs before you leave and leave the t-case in 2wd untill you need the 4wd (at which point your shift on the fly)

Sure all the parts in the front end are spinning but there not under power so the truck still drives as a 2wd.

I do this with my 4runner.
