Its sounds like you have a 208 t-case. The 203 didn't come with atuo hubs or a 2WD feature. And the 205 had manual locking hubs. Check to see if you have a aluminum case. If so.. its a 208.
To fix the front end from walking is to change out the auto hubs and replace with some manual locking hubs. This will let the tires run more freely and will save wear and tear on the drive train and save money in the long run.
Also, in my opnion.. Both the 203 and 208 are just plain junk!! 205 t-case is the way to go. For strenght and very dependable. Hope this helps.. Rock on people!!!!
