Okay, I have recently bought a 83 Fullsize and it has the TTB front setup. I don't really have any clue about 4x4s so I have been reading on different sites and most of the post I have read suggest doing a SAS as soon as possible. Also that the TTB really isn't worth a damn. Is this true or would it be fine running like 35 or 36 with the ttb and still be able to get out and enjoy some trails until I learn more. Or should I just kind of suck it up and save some money and to the axles before anything else? Thanks for the help.
