i have just bought a sportrak and have discovered the front auto locking hubs, don't. The advice appears to be to fit new manual hubs,which i can source for about Ã‚Â£180. I would prefer to fix the old ones if possible, but can anyone tell me what goes wrong with them. The previous owner didn't use it in four wheel drive and owned it for about six years.Could it be just a lubrication problem. Is it easy to swap auto's for manuals Any advice is most welcome. Its a an elxi 1996.
