Well.. im out here in LA(from Fla) getting an 82 pickup from my dad and the 4WD doesn't work! im comming from fuel injected front wheel drive car world; to this nice carb. RWD / 4WD truck ;D but im a fish outta water when it comes to a lot of it mechanically in comparison to my SCC world. especially in a different city with no friends to ask. The hubs lock, so the front axle and driveshaft all spin when locked, but the front wheels wont get any of the power from the transmition it seems. But the 4WD shifter is pretty screwy as well... it doesn't follow the pattern on the shifter knob Or the shifter pattern in the owners manual(which are the same). the pattern shown is left and up= H2 then down and to the right is H4 and up one place is N and all the way up is L4... but it shifts differenty like a mirrored h (rather then a 5 point J) with the bottom left being a 4WD position(i assume since the light comes on in the dash) and up and over to the right is then N and then to bottom right is a high gear position, and up all the way to the position is a low gear position without. and the light only comes on in the bottom left position it drives in the high and low positions on the right but only in 2WD even with the hubs locked, all it does is spin with the tires, not spinning the tires. and in the shifter position where the 4WD light comes on, it doesn't move at all. besides that the truck is awesome, some old guy and then my dad have had it since the dealership.. baby driven all it's life with no rust, an 89 pioneer stereo with matching amp and 6x9's lol  an old school toppe with the bed all carpeted-out like a camper. after market monroe magnum lt shocks that are probably from around the same time as the radio and some 31's(but i think 31's were stock on the sr5?) Anyways, if any of you could help me out to what the problem is or what i am doing wrong, it would be a great help! and any other possible problems to look at before i drive 3,000 miles to florida.. besides a complete tune-up and all fluid replacement, etc. i appreciate whoever takes the time to read this super-long write-up but i just wanted to be as clear on the details i do know as possible, -BeN² |

Ok, here's the basic operation of the Toy t-case.
The shifter works 2 different sections of the t-case.
On the right side is the 2WD/4WD rail, which is enaged when the shifter is on the left. When the shifter is on the right, it engages the HI/N/LO rail on the left side of the t-case. An interlock pin between the 2 rails forces you to use the 2HI/4HI/N/4LO pattern only.
It may be that someone has removed the t-case shifter and reinstalled it incorrectly (yes, this can happen a couple of ways) and would result in a screwy shift pattern as you describe.
Another possibility is that the case has been disassembled and reassembled incorrectly, or, something is broken in the shift rail area.

Are you sure the hubs are locking? I had the same problem and took off a hub to inspect it, looked fine to me! but it still wasn't working. I then took off the other hub and it was completely rusted and stuck. I got new hubs and the 4wd works great now.

thanks for the info. i was told that the transfer case was rebuilt, and then the guy(1st owner) never used the 4WD since or something.... and when my dad bought it the 4WD didn't/doesn't work.. so that sounds like the problem with it is related to your possibilities you said.
with the shifter being installed the wrong way, is that something that can just be re-installed correctly, easily, or do i have to drop the transfer case to get it re-installed/would it have been damaged from being used wrong for a while at least?
do you know of any ways to figure out which way it's screwed up without taking it apart first?
thanks for the help, im just trying to figure out what i need to start working on first when i get back to florida with it.

i dont know for sure, new to the truck world ... but we locked both hubs(they were in the lock pos. anyways) and drove forward and reverse, and it spun the front driveshaft. we tried spinning in the sand and it didn't bite, with the front tires( it wasn't really sand as much as some loose gravel over hardened dirt.. ) but when it had the 4WD light on it didn't move at all.
but i didn't try locking one hub at a time to see if it was just one of the hubs spinning the drive shaft the whole time either, because i wasn't sure if it was bad to drive with just one hub locked even for a couple feet under a couple mph. and i haven't taken anything apart either. but i could try locking one at a time tomorrow sometime.. i kinda want to stray away from taking anything apart before i make this road trip cross country.. as long as it's not something that'll break half way anyways.. mainly trying to get an idea on what to take apart when i do get there. thanks for the other options , i hope it's something easier like that, keep the help comming, i need a lot of it i think...

There is no way to tell with out taking something out first. If the shift lever is installed incorrectly, take off the shift boots and you will see 4 bolts holding the shift lever to the transfer case. (they were very hard to reach on my truck). Simply unbolt them, turn it 180 degrees and re-bolt it. If this doesn't work, its the hubs.
or
you could take off both hubs (you must take off both, you don't know which is rusted). To take of the hubs, first turn them to "free" then take off the six bolts hold the front part on and slide it out. Once this is off ,you can see whether or not it is rusted.
If both hubs appear to be in good working order, then the problem is in the axle. possibly the birfield joint.
Hope this helps!

This cab be done from inside the cab. Been there, done that. ;D The key is to determine if 1) the shift rails were in the correct positions and the shifter was just installed in the wrong "slot", or 2) the shift rails were not in the correct position when the shifter was installed. (If they're not they can be pryed into correct position w/a large screw driver.) Somewhere at home I have a diagram of what the shift rails should look like in the 2WD HI position. This is for a forward shift case, but I think it would also apply to your top shift case. If I can find it I will try to post it somehow. |

fixed it.. well.. i assume the shifted was somehow installed, not upside down- but with the end in the wrong spot.. i took the shifter out, and looked at the two rails that were exposed to me. started moving em to see what they did, which ones engaged the front drive shaft because i could see it through the hole in the hump, and then looked at the knob on the shifted and guessed at what position the rails started at, and then as the top of the shifter moved one direction, the end on the bottom moved the opposite, (if you hold a pencil in your fingers in the middle and move the top one way, the bottom moves the other way) and just messed with the rails until i figured out what position they needed to be in, which rails did what, and then put it back together and works like a charm. sometimes it doesn't wanna shift out of fwd but i just fiddle fart with going forward and backward, stop and go and it'll work within a minute. it has made such a difference, and now im hooked... i had gone off roading with a buddy before and 2wd will definetly keep you humble, but it's such an insaine difference.. but anyways- now i want bigger tires because all we have here in florida is mud, soupy mud, and more mudd.. no climbing with no elevation.- BeN

thanks for the tip, is it bad to go short distances in 2wd w/out getting out and locking the hubs? for example, if i am going down a trail or whatever, is it bad to put it in 2wd w/out unlocking the hubs until the next mud hole (cause that's all im stuck with in florida)? - BeN
