Escogiendo la relación de transmisión correcta-Video
Existen tres razones principales para reemplazar los engranajes de tu vehículo. El primero es para recuperar la capacidad de la conducción y la eficiencia de combustible de un vehículo de conducción diaria que ha sido modificado con rines y llantas más grandes. El segundo es afinar las características de rendimiento de un vehículo que es dedicado para todoterreno, donde el enfoque está más en el poder y la aceleración. El tercero es mejorar la eficiencia del combustible. El video adjunto describe el por qué y las consideraciones que deben tenerse en cuenta para encontrar la relación de transmisión correcta para su vehículo.
How It Works: Yukon Dana 30 CAD Delete Kit
What is CAD? What is CAD? It’s not short for Cadillac… In this case it’s not the acronym for Computer Aided Design… For our purpose CAD stands for "Central Axle Disconnect." At its core, the Yukon Dana 30 CAD Delete Kit blocks off the vacuum actuated engagement of four-wheel drive in Dana 30 differentials. Select Jeep vehicles produced from 1984 to 2001 are equipped with the automaker’s reverse rotation Dana 30 differential that’s outfitted with the Central Axle Disconnect (CAD) system. The system components, located on the passenger-side axle tube, consist of a two-piece splined shaft and a coupler that a vacuum-operated shift fork actuates to connect or disconnect the axle, which engages or disengages four-wheel drive. Dana 30 Heritage The Dana 30 has been the go-to front diff for the Jeep Wrangler since the model’s Jurassic Period… CJ-5 models of the early 1970s. Available in high- and low-pinion versions as well as standard and reverse rotation versions, the Dana 30 is an important building block in the Jeep hierarchy. There are tons of aftermarket parts for this differential and spares waiting for rescue in junkyards across the country. CAD Versus The Elements Time is no friend to the CAD system. The vacuum lines can crack, the vacuum motor can fail, or the system can be compromised in another manner, and cause the Jeep to be stuck in two-wheel-drive… that’s no fun. Further, the two-piece axle is not as strong as a one-piece design. Fortunately, the stronger and more reliable one-piece axle from a TJ or ‘non-disconnect’ XJ are direct swaps. The catch… sealing the housing post-swap. Yukon To The Rescue Enter the Yukon Dana 30 CAD Delete Kit. It consists of a disconnect housing blocking plate, gasket, and inner axle seals that will accommodate a one-piece axle design.

Decoding Differential Tags - Video
Auto manufactures have made it possible to glean basic but useable differential information by means of tags, stickers or stampings on the differential. The tags are usually affixed to the pumpkin by a diff cover bolt and stickers can be on the housing or axle tube close to the housing. The “direct from the source” aspect of this information makes it hyper accurate, overriding any confusing make, model, engine, and transmission information mash-up. No late night research needed. It’s all right there, straight from the manufacturer. The accompanying videos outline what info is on Ford and GM tags and what it means to you.
The Sounds Of Death: A Failing Differential Story
Breaking a differential can be a sudden, horrific event. If you’ve haunted the drag strip you’ve undoubtedly seen the loud, fully cammed hot rod drop the clutch then drop a load of gears and metal on the track. Out on the trail, a struggling rig finally hooks up and the sudden torque is too much for the diff, grenading the unit to its ultimate demise. Read this article in Español A differential can also die slowly and alert you to its impending doom. A vehicle in motion makes many different sounds, most are relaying a harmonious state of being. But there can be tremors in The Force. As things start going sideways in a differential there are noises that serve as clues to what’s happening and knowing the what the noises mean will help you determine what may be wrong. To this end, we are offering this rundown of common noises and their likely point of origin. The Sounds Of Death A “whirring” sound generated by unloading via deceleration from most any regular road speed can likely be traced to pinion bearing failure or poor pinion bearing preload. This malady is often diagnosed as a bad ring and pinion gear. Generating a “whine” or “howling” sound under positive load i.e. acceleration is more in line with a worn or failing ring and pinion gear or a ring and pinion gear set that has not been setup correctly. If you detect a “rumbling” sound at speeds above 20 mph that tends to change frequency while the vehicle is turning it may be caused by worn carrier bearings. But it could also be bad wheel bearings. To confirm, jack up the vehicle at the offending corner and shake the tire. If there is a lot of play in the wheel/tire, the wheel bearing is most likely the culprit. [At Left: Here’s a real screamer. Crush sleeve or pinion bearing failure resulted in the pinion gear trying to eat the carrier.] A regular rhythmic “clunking” or “clicking” detected every few feet may be a broken tooth on your ring or pinion gear. If you have recently swapped on new rolling stock, check the inside of the wheel for an exposed clip-on external wheel weight that may be hitting the shock body on every revolution. A more aggressing “clunking” that borders on “banging” that happens when cornering may be caused by broken spider gears, poorly lubricated limited slip differential or positraction units, or worn clutch packs in limited slip differential or positraction units. Basic Ground Rules In this process hearing the sound is easy enough… it’s tracing the source that gets tricky. The big challenge is discerning a failing bearing within the diff to a wheel bearing that is going south. The sound is similar. One of the determining factors is the fact that the wheel bearing noise will change with wheel speed but usually will not change with load variations i.e. acceleration or deceleration but the sound from a wounded rear differential will change with wheel speed and load. Listen with Your Eyes Leaks are warning signs too. They can be precursors to trouble or the result of trouble. While some fluid under the vehicle can be part of condensation from normal operation, noticing reddish drips can be a sign of leaking transmission fluid. A compromised seal or gasket steals away vital lubrication resulting in dry, overheated internals and impending failure. The bottom line here is any noise emanating from your drivetrain, whether you can locate its root source on not, is serious business. Tracking down the cause is critical to prevent more serious damage and more expensive repairs.

Yukon Vehicle Recovery Gear
Getting unstuck is part of wheeling. Do it right, and it’s a fun part of wheeling. Whether you’re pulling a friend free or winching yourself out, Yukon Gear & Axle recovery gear has what it takes to get you back on the trail. When shopping recovery gear, remember that a recovery rope’s strength rating needs to surpass the gross vehicle weight of the rig you’re extracting by two to three times. What is a Kinetic Recovery Rope? Kinetic recovery ropes, also known as snatch ropes or yanker ropes, are designed to have some stretch so you can yank a vehicle free. You’re not towing here—tow ropes are designed with no stretch for consistent pulling when towing. Tow ropes can produce sudden shock to both vehicles and put undue stress on their attachment points when used in a recovery scenario. Yukon Recovery Ropes can stretch by up to 30 percent of their static length, which stores kinetic energy. The rope then smoothly transfers that energy into pulling power to rescue a vehicle that is stuck. The rope’s elasticity also makes it easier for the rescue vehicle to generate momentum, especially in loose footing like sand, gravel, or mud, where a non-kinetic rope could cause the rescue vehicle to bury itself. Yukon recovery ropes are up to the task. Our largest offering is 7/8” in diameter, 30 feet in length, and rated to 28,000 psi Minimum Tensile Strength. Our other recovery rope is 3/4” in diameter, 20 feet in length, and rated to 19,000 psi Minimum Tensile Strength. Securing to an Anchor Point Ropes are important, but they have to attach securely to the vehicle to be effective. Enter the shackle. Yukon offers two types of shackles: a metal D-ring shackle and a soft shackle made from nylon plasma fiber. Each type has its strengths and weaknesses, and both should be part of your recovery gear assemblage. Metal D-ring shackles, also known as bow shackles, pin shackles, or anchor shackles, are cheaper and stronger than their nylon cousin. Metal shackles excel at attaching a recovery rope to a vehicle but should not be used to join ropes, connect a tree strap, or link to a ground anchor, because if the rope fails, the metal shackle becomes a projectile. The soft shackle shines in situations where you want to join ropes, use a tree strap, or employ some type of ground anchor. Joining ropes extends your reach. Tree straps are gentler on tree trunks than coarse winch rope. A ground anchor is a large and sometimes cumbersome piece of kit used when no trees or boulders are available. Soft shackles are stout and much less dangerous in case of failure. They are flexible, adept in high-angle rescues, and float, making them ideal for mud or water recoveries. Rating the Strength of Recovery Equipment Soft shackles and recovery ropes are typically rated by Minimum Tensile Strength (MTS), which is the amount of tensional force a material can endure without failing. Measurements are calculated using pounds per square inch (psi). Taking that failure point and applying an industry-standard 5:1 Safety Factor yields the recommended Working Load Limit (WLL) of a given product. This is the load at which the product is safe to use. Yukon recovery products are listed with both MTS and WLL—ropes and soft shackles using MTS, and the metal D-ring shackle using WLL. Our soft shackles are flexible, buoyant in water, and have a load rating of 35,000 psi MTS. The steel D-ring shackle is listed as 9,500 pounds (4.75 tons) WLL. Using the standard 5:1 formula, the actual MTS breaking strength would be around 47,500 psi. Yukon recovery gear is rated to handle the bulkiest off-roaders so you can hook up and pull with confidence. Yukon offers recovery gear as individual pieces or as convenient kits that pack all the typical gear you’ll need—kinetic recovery rope, hard and soft shackles, and gloves—into a tough nylon bag. These kits are great starting points and can be added to with other recovery gear or trail repair necessities as needed. Fortune favors the prepared mind, so be ready to rise to any challenge with Yukon off-road recovery gear.
