does my jeep have limited slip diffs?Remember Me? Site Navigation. How important is locking rear differential? I'm on an overly long and convoluted journey to having a vehicle to take off-road Had been looking at a new 4Runner, but am now feeling more like I don't want a car loan and buying something used. The 4th Generation 4Runners don't appear to have had locking rear differential as an option. I'm not an experienced off-roader, but I've been given lots of advice that this is one of the must-have options. Yet it's not even available for many years in 4Runners. Thanks for any advice! I Spent eight years crawling through the Sierra's in Northern California and got into many rough places. I had locking rears and never had to use it. But it was comforting to know that if I ran across certain situations it would be available. I also pulled a heavy boat out of Lake Oroville each season and by that time the lake had dropped below the end of the ramp and I was in mud, wood chips, bark, and other small garbage. The ramp was close to 45 degrees when that low and I never needed anything but 4LO to get moving and as soon as I was on the solid surface of the ramp I changed over to 4HI and went on up. The ramp can get pretty long at the end of summer with a lot of the water being sent down river for irrigation and drinking water. Last edited by chaz; at PM. Member's Picture Albums. I don't think it's necessary for your intended use. However, like chaz said, some of the models have a locking rear differential. A locking rear diff can be added to about any vehicle with companys like ARB. They make lockers for all model 4runners. You may never need one but that one time you do when you are many miles from help and you are by yourself it will be well worth it. Check out the videos of me in the photobucket in this link. A-trac concerns, 1st attempt at video A locker would have had no problems here when the atrac was limited. I'm not sure if FJs appeal to you at all, but rear lockers are much more common on FJ's and there's some pretty decent prices on used ones. I think you have to get the offroad package, but there are plenty of them out there. The '09 TE 4runner is damn near impossible to find and you'll pay more for it. Good luck and let us know what you go with! Follow us on YouTube and Instagram. Originally Posted by jhmoore. Find More Posts by KidVermicious. Lockers are not a "must have" for your average wheeler. But they are nice to have, and can always be added later.
How to Identify Wrangler Axles & Axle Differences
A differential is a set of gears that enables your vehicle's wheels to rotate at different speeds. A fixed axle supports only one speed of the wheels. When turning, the inside radius is smaller than the outside, causing a fixed axle to drag one wheel. A limited slip differential, or LSD, has a set of clutch plates that inhibit the free rotation of either wheel. These clutch plates enable each wheel to retain some power while cornering. Limited slip differentials require a certain amount of friction modifiers in the gear oil of the differential to operate properly. Inspect the differential for a metal tag or model marking. Some manufacturers, such as Ford Motor Company, will mark the differential in some way that designates it as a limited slip differential. The Ford markings, for example, will have an "L" on the differential model number indicated limited slip. Consult your manufacturer for details on tag location and identification. Read the manufacturer sticker on the driver's side door. Some manufacturers will specifically identify whether the model was shipped from the factory with a limited slip differential. Decode the VIN number for your vehicle. VIN numbers may contain information that specify whether the vehicle was shipped from the manufacturer with a limited slip differential. Be sure the differential installed is the same one installed from the manufacturer. Place the vehicle in "Park" if it is has an automatic transmission, or in first gear if it has a manual transmission. Brace the two tires, with wheel chocks, on the axle you will not be inspecting. Jack the vehicle to lift the two tires--on the axle with the differential you are inspecting--off the ground. Turn the tire on one of the lifted wheels slowly. Use your hand to turn the tire. If the differential is limited slip, the wheel will be difficult to turn. If the differential is an open differential--also known as a conventional differential--the wheel will turn freely. Turn the tire again. The tire should turn more freely on a limited slip. Also, the opposite tire will turn in the same direction. If your vehicle is equipped with an open differential, the wheel on the other side of the axle will turn in the opposite direction.

A Simple Guide to the G80 Locking Differential
Ten Stupid Things men do to mess up their 4WD. Other terms used for differential locks are: locker, diff locks, diff lockers, differential lockers Unfortunately, limited slip differentials LSavailable as options for many 4x4 in the US are offered by sales people as "locking differentials". They are by far inferior to a differential that is truly manually or automatically lockable. If you have to decide whether to get a "locking differential" aka limited slip LSif available as an option on your new truck, I would recommend getting it, because it is still better than not having anything at all. To repeat: "locking differentials" are limited slip differentials that are not to be confused with differential lock! Is this already consumer fraud? Now here is a twist to the locking differential story : When Chevy advertises its trucks with an optional rear locking differential - it indeed is a differential that locks up automatically. In the 80's it was sold as a Gov-Lok for a while named Command-Traxx and is available in some Chevy trucks as G80 option. It is not manually activated as in Dodge, Jeep and Mercedes - it locks up automatically. In addition to factory installed diff locks, there are several aftermarket options to add a differential lock to front and rear axles. Recently we saw some newcomers like the OX Locker which seems like a copy of a long know German Schwarz locker to me.
Open VS Locked Differentials
Written By: Louis Orellana. A Wrangler's drivetrain is its bread and butter. That said, there is always room for improvement, or to hone it to your off-road needs. Stronger axles, different gear ratios, and even a tougher differential will help you tackle more difficult trails. Wranglers are known to have a terrain capable and rugged drivetrain. The solid axle design paired with an incredible 4WD system, provides Jeeps with a high degree of versatility and durability. This article will explain the differences between Jeep axles, offer a brief explanation of how the legendary 4WD system works, and show you which differential cover belongs to which axle. The Dana portion is the nameplate of Dana Inc. There have been a few different axles used in Wranglers over the years with the Dana 44 being the most popular. The Dana 30 will only be found as a Jeep front axle while the Dana 35 will only be found as a rear axle on Wranglers. Dana 35 axles have earned a very poor reputation in the off-roading world, however, it is a great axle for stock Wranglers. If you intend on running 33 inch or larger tires on your Wrangler, make sure you have a Dana If you try running huge tires on a Dana 35 you will probably end up snapping an axle shaft. Each Wrangler axle has a slightly different look, making them easy to distinguish. The graphic below will show the appearance differences. A Dana 30 cover will look like a rounded square. It should have 10 bolt holes and is 9 inches wide. A Dana 35 cover will look like an oval. Identifying the axles in YJs is pretty simple since there were no options for it. Every YJ came with a Dana 30 up front and a Dana 35 in the rear. TJ Wranglers will have either a Dana 30 in the front and a Dana 35 in the rear unless you have a Rubicon model.
