We took the JETOUR 1 and JETOUR 2 through our off-road training area to see what this 4×4 with no Low Range could do. Here’s what we found.
Up-Armoured Vehicles: Understanding Off-Road Capability
Why spend loads of time and effort up-armouring only to produce a vehicle with poor driveability? Some companies do this better than others, so it’s important that the operator has a clear understanding of the positive and negative effects that the up-armouring process produces.
Breathing In and Breathing Out
If your drivetrain springs a leak, it could be that the breather/s are blocked. After plugging the leak, it’s important to clear the breather.
CHANGING SPEED AND DIRECTION – Wheel Printing
It’s always a good idea to make sure there’s enough traction available to change speed and direction; under control. And … keep the vehicle moving.
Releasing Axle Wind-Up
Axle windup is the build-up of drivetrain tension when cornering with 4wd engaged (part-time) or centre diff locked (full-time). Possibly damaging.
Managing Available Traction
Wheel printing and the ability to identify when to drive as slow as possible but as fast as necessary.
Low Traction Road Surface
Unsealed roads, particularly when dry, need to be treated as a low traction surface.
Has Your 4wd’s Approach Angle Been Compromised?
Whenever you fit something to a 4wd vehicle, there will be a trade off. Understanding this compromise is essential to managing not only your off road capability but also for driving defensively.
My Thoughts on Using Synthetic Shackles
Recently purchased some synthetic shackles (Gator-Jaw) from Bubba Rope in the States. I had gotten one of their kinetic energy ropes through someone that was leaving Uganda and was very impressed.
Why I Don’t Like Roof Racks
I don’t like roof racks and don’t have them fitted to any of our vehicles. Reasons for this dislike are many but the main one is safety. Roof racks encourage loading fairly heavy stuff on the top of vehicles.
Why You Should Care Which Handbrake System Your 4wd Has
There are two common types of handbrake systems fitted to 4wd vehicles: A handbrake which works on the rear brake shoes. A transmission brake that is fitted to the rear output of the transfer box.
