I have a 96 F150 and when pull it back in to 4 wheel, and start to move it jerks and like a hard pop almost and then it goes in. Also it jumps sometimes when backing out or things. I was just checking to see if there was a problem that any of you knew about. Thanks.

 

Are you putting it in 4 high or 4 low? 4x4 always works weird in reverse, I usually avoid that as much as possible.

 

Just regular 4 High, it does it whenever i put it in and begins to move and kicks in. It goes good once in use, i try not to use it much.

 

auto locking hubs? if so that is your problem. same thing with mine untill i swapped to manual. they are engaged by torque

 

Yeah that's what I thought to, how much do they cost, any idea?

 

This truck has about 163,00 on it and I know the striaght six run forever, but i dont want to put alot of money into it and then have to replace a lot of stuff. I would like to lift it.

 

i just bought mile marker 104 premium hubs for 65.00
