I have an 84 pick up. I can't keep the front seals from leaking. I've heard that I can swap out my old front end with the locking hubs, and put on a new front end and be able to go to 4 wheel drive from the cab. Has anyone heard of such a thing? is it costly? Thanks!

 

Just lock in the hubs when you leave the hard road and shift the transfer case in and out when you need 4wd
