4x4 question
Hey guys I have a question. I had my truck lifted a month ago,I took my truck into the dealer to have the brakes replaced and they mentioned to me that whoever installed the lift didn't put an extention on the 4x4 vacuum line and he said if I went off roading and the wheel extended to far from the wheel well my 4 wheel drive would go out. Is this statement true. If so I shouldn't have to pay for the extention should I it should have been included in the work I'm assuming. I'm not to familiar with all of the specific parts and everything when it comes to 4x4's but I'm learning more and more with this site. Thanks in advance.

When you start the truck it sends vacuum to the hubs and unlocks them. I would definitely get extensions as it should have been done in the first place.
