The rear differential on a Hummer H1 lies right in the middle, but the front differential is skewed toward the driver's side, so here's how to center it.

The H1 half-shaft is a driveshaft assembly that runs from the differential out to the hub, delivering power to the wheel, and with an independent suspension all the way around.

Not since the old Hummer Challenge events in the Ocala National Parks has there been an event where Hummer drivers from around the country could compete against one another. Until now, that is.

"Crazy mad flex!...the best $300 mod any H3 driver could ever make."

Since AM General started making civilian Hummers back in 1992, they have been among the heaviest vehicles on the trails.

In 1912, Rudolf Diesel said, “The use of plant oil as fuel may seem insignificant today.   But such products can in time become just as important as kerosene and those coal-tar products of today.”

At first glance, you might guess that the X is a wildcard that means that it doesn't matter whether you drive an H1, H2 or H3, and you would be partly right.

Amazingly, the month of January has passed, and we only got about 3 snowfalls with any accumulation, so my snowplow testing has not been as extensive as I had hoped.

Who in their right mind would pay 1.25 million dollars for a pre-owned 1993 Hummer H1?
