I removed my front drive shaft on my 2006 PF due to vibration issues and have been driving around with the switch in 2wd. I was looking at some other forums regarding Titans and one guy said that there is an oil pump/motor? in the transfer case and that if you plan on driving without the front drive shaft that you should put the switch in 4wd so that the pump/motor? in the transfer case is functional.
Is this true ?
