TECH ARTICLES By Dan the Gear Man

QUAD 4x4 is home to one of Americas top 4x4 drivetrain specialists, our own Dan the Gear Man™! Dan has over 30 years experience in maintaining and repairing 4x4 drivetrains and chassis components. Dan is a frequent contributor of tech articles for the Turbo Diesel Register and other national publications.  He also wrote "Living in Pleasant Valleys, Life in Carbon County Montana", a 170 page book that was a local best seller with five printings.  In addition, Dan directs and narrates numerous detailed instructional videos covering a wide range of under vehicle 4x4 service.  Each video covers a specific service job and shows every step required for a particular repair.

As time permits, Dan will be posting all his past articles to our website, plus adding some new ones.
