There’s a lot riding on your axles… literally. There are all kinds of variables at work here… one of the more misunderstood is axle type. There are two styles of axles used in the rear of light-duty, four-wheel-drive trucks and SUVs; semi-float and full-float. Understanding Semi-Float Axles A semi-float axle features splines on its inner end to connect with the...
Q- Can you advise on a recommended gear ratio for a 2017 Jeep Wrangler four-door with a 3.6-liter motor running 35 inch tires? … Would it be 4.56 or 4.88? Gus- Is it an automatic or manual transmission? How will it be used? Customer- Automatic. It’s a daily driver and weekend warrior off-roader. I do some off-road driving for my job during the week. I’m running 3.73s...
Pinion bearing preload is a critical step in the differential overhaul process because if you get too heavy handed you have to backtrack and start over. Further, getting this procedure right sets the stage for each following step of reassembly. It should be noted from the get-go that there is a difference between the minimum torque value for the pinion nut and the pinion bearing preload. The...
Transfer case season is upon us. As the leaves fall and temperatures drop it’s a clear sign that driving conditions are about to worsen. This is the time of year we rely on our drivetrain more and unit failures tend to go up. This is especially evident around that first snowfall of the season. Zumbrota Drivetrain is ready for the season with many popular tried-and-proven remanufactured...
The trail can be rough on your Wrangler. Protruding obstacles conspire to damage rocker panels and underpinnings. Bumpers can take a beating but they also need to do more than sit there. A properly outfitted bumper will increase your approach/departure angle, serve as a tow point for rescue, house additional lighting, and secure your all-important winch. Fortify your JK, JL, or JT...
Go low, get more grip. Experienced off-roaders know dropping air pressure can transform your trail running experience. The benefits include improved ride quality, especially over undulating washboard surfaces, a larger contact patch for increased traction, and the ability to grip and climb rocks and other jagged obstacles. However, running at very low pressures also increases the...
Wheels from ICON Alloys are the perfect blend of form and function. ICON wheels are engineered on a per-application basis to maximize caliper clearance and optimize wheel position for un-hindered suspension travel and steering function. Backspace and wheel offset dimensions have been strategically developed to reduce scrub radius, improving all-around handling and ride quality. Choose from...
RANDYS is excited to be selling ICON Vehicle Dynamics products. We will be offering ICON suspension systems, steering components, body armor, and signature wheels. Understanding ICON’s line of shocks will help you make the right decision on upgrading your ride’s suspension be it via shocks only or by employing a complete suspension lift system. ICON shock absorbers are available in...
When you’re driving in a normal manner a positraction limited slip differential is pre-loaded and provides equal traction to both wheels. Mashing the throttle, taking a tight corner aggressively, or working through loose gravel trails will result in the limited slip differential applying more torque where it’s needed. This enhances the grip, control, and predictability of the vehicle....
Gear break-in consists of controlled heat cycling of the gear set in a way that properly seasons or hardens the gear’s contact surfaces. It is a series of test drives. These critical first few miles of drive time can be the difference between a gear-melting headache and years of carefree driving. Failure to properly break-in your gear set can result in damaged, failing gears, and a complete...
