4 wd noises??
When I put my 08 6.4 Crew Cab into 4 wheel drive there is a squeaking noise coming from the front end. It sounds like it is coming from the drivers side front wheel. I squeaks as the tires rotate. This is a very noticeable noise. The noise goes away after a minute or two. I have had my truck back to the dealer 4 times for this issue and they cannot find any problems as the noise goes away after the hubs warm up. I started complaining about this at 35,000 miles and my truck goes in Monday for my 50,000 mile service. I am going to have them check it again. The drive train warranty goes out at 60,000 miles. If I were to attempt to sell my truck this would be an issue and I want it fixed under warranty. Has anyone else had a similar problem?
