General information about the various mods available to 4x4 vehicles covering pros and cons to assist in the decision of "Is this the right mod?"

John Stewart

"Check Engine" Light

In general, all vehicles equipped with on-board diagnostic systems (OBD-II is the current standard) will store error codes that can be read using a portable code reader.  A "Check Engine" light comes on to indicate that the engine management computer has detected a problem related to emissions or engine operation.  It is your notice that something needs to be fixed in order to comply with federal emissions requirements or to keep your engine running. Many of the trouble codes relate to engine or emission sensor inputs that have failed or are out of tolerance.  The sensors control the "engine management computer" and keep the engine running at optimum efficiency.  Failed or out of tolerance sensors mean your engine is not operating at optimum efficiency.While it is easier to read the fault codes with a code reader/scanner, most vehicle provide an option to display the codes.  To view the codes, start with the engine turned off.  Turn the ignition key to the "ON" (not "IGNITION/START") position, then turn it off for about a second.  Turn it on for a second, then turn it off for a second. The third time you turn it on, you should see a set of trouble codes flashing on the odometer display.  (NOTE: this process works with most newer Jeep vehicles.  It may or may not work with other models.)Once the error codes are recorded, interpretation will indicate the likely source of the fault. Fixing the problem can be simple do-it-yourself (replace the gas cap) or more complex requiring the services of an auto repair shop.

Building a General Purpose Mobile Comms Suite

I like to get out with a purpose.  Usually, my rig takes me places where I like to do other things.  I have bikes, kayaks and feet that like to get away from the vehicle more than I tend to take the truck down trails these days.  This is not to say that 4 wheeling is not a goal; time to take advantage of extended outings just hasn't been in abundance.  That said, I decided that I wanted a communication system that would function with a general purpose.  I wanted to use both amateur radio frequencies and CB communications.

Staun Internal Beadlock Install

One Piece Alloy WheelFirst, you need to determine if your rims are acceptable for the Staun internal beadlock.  Acceptable means one piece alloy or steel rims.  And, even if it is a one piece rim, there may be a structure issue that makes a particular style of rim a bad choice.  

The internal beadlock is a tire within a tire.  One hole is required to be drilled in the rim for the valve stem of the inner tire.  And, it requires a flat surface that is parallel on the inside and outside in a location that does not interfere with the brake assembly.
