I am looking to purchase an 82 Brat. Here is the issue it has: the front wheels do not engage. The car therefore cannot be driven in normal AWD, but the back wheels will engage when locked into 4WD. The owner says that he thinks it is something with the axle being worn out and not fitting into the hub, and purchased an axle to replace the worn one, but never got around to doing so.
My concern is that the axle is not the problem. One source told me that I should assume it will need a new transmission. Looking around, I thought that it could also maybe be the front diff, or the transfer case.
Any feedback would be great before I pull the trigger.
