Does anyone know if warn hubs can be installed to replace the auto hub vacuum control engagement. I use to own a 1971 Jeepster commando. When the hubs were locked, going into 4 wheel was immediate. I hate the slow responce of the 4x4 engagement on my Dodge. In very cold temp it takes to long to engage. I had the dealer check this out but was told this is normal. This auto hub invention belongs to the yuppies who don't want to get there feet wet to lock hubs.
