I had the same problem with my 91 Geo Tracker manual hubs...my hubs were siezed up inside. We pulled the hubs off (simple procedure) and found that the *sliding outer gear was frozen solid (rusted), so the man. hubs wouldn't engage when turned to lock position. We slid out the outer gear, and cleaned it up a little. (doesn't require grease). Had to reattach the end of the coiled spring to the inside grove of the outer gear (little tricky), and remounted the hubs on the outer axle and it works fine.
how to replace the light bulb on the gear shift on 2004 tracker
I know in mine which is a 4x4, it means the 4x4 is engaged. The little care picture thing is your vehicle information center. When it is in just 2 wheel drive, only the lights for the rear wheels should be on.
Your transfer case fluid level may be low. It was on my 2000 and it was extremely difficult (i.e. almost impossible) to shift into 4 high from 2 high, whether stopped or moving. I got the fluid changed and you could use a single finger to shift it after that. If you are trying to shift when the vehicle is moving, make sure the front wheels are fairly straight and your speed is low. Also if you are moving on bare pavement it may be harder. The 4wd systems on the tracker don't use transfer case clutches, so it relies on wheel spin to keep the fron axle in sync with the rear. The wheels won't spin on paved surfaces and the vehicle computer will sometimes prevent a shift. That's also why there is a delay when shifting in 4wd. Hope this helps.
The actuator on a 4-wheel drive allows the vehicle to shift into 4-wheel drive with the push of a button or a shift of a lever. The actuator allows the front axle to become engaged.

can not get 4 wheel drive to shift in 1998 Tahoe
The clutch disc may have shredded.
I tow a 02 ZR2 4X4 w/auto. I would think its the same so this may help. With the auto transmission in "PARK" and the transfer shift lever in "NEUTRAL" turn your ignition key to "ACCESS" position so the front wheels don't lock and are free to turn. I've towed many miles but I also turn the tracker on every 2-3 hundred miles and shift the transmission back to normal and go thru the forward gear positions to lubrecate itself for insurance. Double chk. shift lever positions before toweing again and leave emergency brk OFF. Good luck.......
There is a shift fork that is engaged using vacuum from the motor. The shift fork is located inside the front axle more towards the passenger side. When you engage four wheel drive it lets the vacuum go down to a motor that moves the fork to lock the hubs
Yes, but its a lot of work, you've got to change the transmission, put a front axle in it and all of its parts you've got to go inside then and move the consol so you can put the shift thru, cause the hole for it is there its just covered up.
I have a 2005 which does have locking hubs, but that is so you can lock your differential from slipping. If you're stuck on a hill with all 4 wheels spinning, lock the hubs and your gear ratio is far apart, your front wheels won't spin, and the front wheels will actually do the pulling. Whether yours has locking hubs depends on the year of F250. Later F250's, I believe beginning with the 1998 models, do have auto-locking / manual hubs. The later F250 hubs can be activated manually or electronically. When you electronically turn on the 4wd ("shift-on-the-fly"), you engage the transfer case, front drive shaft, and front axle shafts. Also, when you electronically turn on the 4wd you activate a vacuum solenoid, which provides a vacuum source to each of your front hubs to engage them. The front hubs only connect the front wheels to the front axle shafts and has nothing to do with the front axle differential, which is an open differential unless you have a differential other than the factory installed piece.
