Top Ten Toyota 4x4 Modifications - Four Wheeler Network
There are some modifications that universally increase trail prowess regardless of what you drive. Instead, we are here to share with you ten modifications specific to ’79-’95 Toyota pickups and 4Runners that will make them more capable on the trail. The reliable engines, excellent wheelbase, and low purchase price make Toyotas a great platform to build on. And now there is a formula to make them reliable and capable, using the parts we have outlined here. The best way to add trail prowess to your Toyota is to add a second T-case and/or T-case gears. The wheelbase of pickups and 4Runners allows enough space for the gear reduction unit of a Toyota RF1A T-case to be added to the drivetrain using an adapter such as this unit from Marlin Crawler. Toyota axles use lightweight, high-clearance stamped steel housings and removable third members like a Ford 9-inch axle. Instead of U-joints, the front axles use a Birfield joint that is a mess to repair on the trail. The factory Birfields are prone to breakage with 35-inch and taller tires, particularly when backing up or when the steering is at full lock. Longfield has solved these issues though with its 4340 chromoly Birfields, available from Trail-Gear. The Longfield Birfields are available in 30-spline (stock is 27-spline) with corresponding chromoly axleshafts. Source: www.fourwheeler.com
