looking to purchase a newer IFS truck, 92-98 style.. what should i look for as problem areas?
my criteria are
extended cab, short bed, 4x4 shifter on the floor, auto, 350
not too much to ask i dont think..
what should i expect to pay?

tia!
 
i would check the cv shafts, make sure the boots are still on them and make sure there are no cracks around the bolts, minor stuff wiper circuit board normally needs replaced if not done yet, wipers only work when they want after the board goes bad, cab corner rust, these trucks are notorious for rusting out there and the bottom of the doors most people i know have to have the tranny replaced shortly after 100000 so if its close and hasn't been replaced take that into consideration. i would aim for the 96 (maybe 95 too not sure)and up with the vortec motor alot more power but it depends on what you are using it for, but i think most of the wortec motor trucks were push button 4x4, as far as price it all depends body condition and miles, you looking for a stock truck or you wanting one lifted? that also has alot to do with price too. lifted ones have more cv shaft problems depending on how wide and big the tires are. hope this isnt too long /forums/images/graemlins/thumb.gif this all stuff i have noticed with my 93 chevy x-cab short bed.
 
the plan is to get one and put a decent set of mud or all terrains on it, until i can afford an SAS.. i wont lift an IFS truck..
my neighbor has an 89 that needs a tranny, its a regular cab, but its not a bad truck, im gonna offer him 800 for it after i sell my honda..

93+
 
Why would someone want to avoid the computer controlled trannies? A simple reprogram and a new firmer shift sounds good to me. /forums/images/graemlins/dunno.gif

One thing is the heated coil dealy that they used for the 4x4 system on the 88-97' IFS trucks. Mid 97's and later had an electric motor to engage the left axle.
 
I thought the computer controlled trannys came out with the second gen computers which i believe came out in 96+.

What were they called? OBD2 i think?

And if you know someone that will give ya the "good guy" price at the local GM dealer, they sell a complete conversion kit to upgrade from the earlier Thermal Linear Actuator to the later elecrtic motor style for about $100. /forums/images/graemlins/thumb.gif

GM started using the computer controlled trannies in '91 or so. BurbinOR has a factory 4L80E in his '91 3/4-ton Sub. /forums/images/graemlins/waytogo.gif Our '94 1/2-ton Sub has a 4L60E. You don't even have to drop the pan on these to install a shift kit. B&M sells an electrical device for about $40 that connects into the harness and lets you select from stock, firm, or extra firm shifts by just moving a rocker switch on the dash. /forums/images/graemlins/cool.gif
 
well the neighbor still has that 89 and he might just give it to me... he wants it out of his yard and if he gets the title i told him to move it into my yard..

Thats what I was thinking of. Computer controlled stuff is expensive to work on but I must say, it's pretty cool to be able to buy plug in parts that drasticly change the amount of power and how it runs without even needing to wash your hands, especially true with the newer diesels. /forums/images/graemlins/bow.gif
 
You could also get the 4x4 posi lock- the PO of my truck installed it. took me a week to figure out what da heck it was for!
