i have a 91 cherokee limited, it has good back tires but the front tires are bald. can i put tires that are the same size but have a different amount of tread on the front. or will the tread difference be to much stress on the t case wile in 4wd?

Ok, I replied to your other question before I saw this. Given this condition of the tires, your problem with shifting out of 4wd probably is driveline windup.

All four tires should be the same size and with the same amount of wear. If they aren't it will cause driveline windup while in 4wd part time modes, which will, as you have already found out, cause difficulties in shifting the t-case, and may indeed cause premature wear or even failure of driveline components.
As you have the 242 case, you have the option of using the 4wd full time mode, but I'm not sure that's a good idea if the tires are badly mismatched; the differential inside the t-case is designed to accomodate minor variations in speed between the front and rear axles, not to be constantly rotating.

If for some reason you can't replace these tires immediately, I would advise the following: 1. Use the good tires on the front axle. Steering and braking is more important than grip for the drive wheels. 2. Don't use 4wd unless you absolutely must, and then only for as short time as possible (to get free if stuck, for example). 3. Replace the tires as soon as you possibly can.

Best regards,

is there some way to fix driveline windup, or will it go away when I get better tires?

I don't think that bald front tires would cause the t-case to bind up. Hey, it's possible, but not to probable. Yes, you could put different tires on the front, even a different tread pattern, as long as all 4 are the same size. You'll want to measure the tires once they are on the Jeep and off the jacks, because not all brands measure what they are supposed to be. I see people run different treads in the front and back all the time.
