1999 Nissan Frontier - 4-Wheel & Off-Road Magazine

What do you do when you have a 2WD truck but a buddy convinces you that you need to be out wheeling 4WD terrain? If you are Greg Ahaszuk of Sahuarita, Arizona, you find a way to get a transfer case and another driven axle under your rig.

Greg picked up a bank-repossessed '99 2WD Nissan Frontier back in 2002 with the intent of making it a lowered street ride. After one trip out with that friend, John James, Greg changed his plans. He soon had some 31-inch tires, a 4WD rear axle, and a Fabtech lift kit for the front. With his new setup, he tackled what he could with a limited-slip rear-driven axle.

When time and funds allowed, Greg bought a salvage 4WD Frontier and cannibalized the steering box, transmission, and transfer case for a paltry $350. With a bit of dirty work and some fabrication, he had a 4WD sitting on 35-inch tires. Following the drivetrain swap, Greg built a tubular bed to replace the factory sheetmetal in back. It's a more appropriate body style for tighter trails, but still retains cargo hauling function for weekend camping trips.

In the end, all it took was one fateful weekend to turn this truck from a pavement pounder to a dirt chaser.

Needing some lower gearing for crawling around washes and boulder trails, Greg opted to split open the transfer case and install 3.92:1 Calmini gears to give him that slow crawl ratio in 4-Lo. A Calmini tranny mount was installed, and Greg fabricated a rear transfer case crossmember, though a slimmer version is in the works.

After the torch and grinder were put away and the area cleared, Greg and John rolled a driver-side-drop Dana 44 under the front of the truck. They fabricated a front leaf spring hanger and punched through the framerails to install homemade offset shackles at the end.

Peek under the rear of the truck and you'll find the stock axle, but internals have been changed and now accommodate 4.9:1 gearing (to match the 4.88 front) and a spooled centersection. Rear suspension is composed of some modified 2WD springs and Rancho shocks. The relatively flat springs ride and flex well on the trail.

Wheeling tight Southwest trails means venturing into ever tighter ravines where rocks seem to jump out and bang straight sheetmetal. Greg opted to remove his factory bed and replace it with a tubular cage and flatbed that still works for hauling camping gear into remote areas.
