How Do I Properly Install a Limited-Slip Differential in My Chrysler’s Transmission?


To install a limited-slip differential in your Chrysler's transmission, first determine the appropriate type—clutch-type for daily use, Torsen for high-speed and complex conditions, or electronic for performance vehicles. Equip yourself with tools such as a socket set, torque wrenches, a differential spreader, and a hydraulic jack. Prepare the vehicle by securing it on a flat surface, engaging the parking brake, and disconnecting the battery. Remove the old differential, marking bearing cap positions, and inspect gears. After confirming compatibility, install the new differential using synthetic 75W-90 gear oil. Test drive and check for leaks or misalignments. These steps pave the way for optimal performance.

Choosing the Right Differential

Choosing the right limited-slip differential (LSD) affects how your car handles and performs. It changes how well your vehicle grips the road, stays stable, and turns corners. Different types of LSDs work better in different conditions and for different driving needs.

Clutch-type LSDs use clutch plates to share out power. They work well for cars that need good traction but are still easy to drive every day. But, they can wear out and need care over time.

Torsen LSDs use gears to manage power. They are great for high-speed and off-road driving. They move power smoothly without extra controls. However, they cost more and are more complex than clutch-type LSDs.

Electronic LSDs allow you to control how power is shared in different situations. They adjust as needed and are often found in high-performance cars, like some Chrysler models. They help the car handle better.

Think about how you drive and what your car needs when picking an LSD. This ensures your car performs well and lasts longer.

Gathering Necessary Tools

To install your new limited-slip differential, you'll need some tools to make the job easier. Gather a socket set with both metric and SAE sizes. This will help you handle different bolt sizes on your Chrysler's transmission.

Get torque wrenches to tighten bolts to the correct level. This stops them from being too loose or too tight, which can cause problems.

Use a differential spreader to take out and put in the new differential without harming other parts around it. You'll also need a hydraulic floor jack and jack stands to lift and hold the car safely while you work.

A breaker bar helps with bolts that won't budge since it gives you extra force. A dial indicator gauge checks how the differential fits together for smooth operation. A pry bar is useful for removing the old differential.

Have a gasket scraper and sealant ready to clean surfaces and stop leaks. Wear safety goggles and gloves to keep safe from debris and sharp edges.

It's handy to have a repair manual or Chrysler's factory service manual. They give specific steps and details, making sure you do everything right.

Preparing Your Vehicle

Get your vehicle ready before you start installing the differential. Park your Chrysler on a flat surface so it doesn't roll or move. Use the parking brake and put wheel chocks behind the rear wheels to keep it steady.

Lift the car with a hydraulic jack and support it with jack stands under the frame. Make sure the stands are stable before you go under the vehicle. Disconnect the negative battery cable to avoid any electrical mishaps.

Check that your workspace is bright and free of clutter. Have all the tools and materials you need close by so you don't have to stop once you begin.

Look over nearby parts for any wear or damage to prevent future issues.

Removing the Old Differential

Make sure your car is lifted securely and won't move around. This keeps you safe and lets you reach everything easily.

Once your car is steady, find the differential housing at the back axle. Grab a wrench and take off the bolts holding the differential cover. Let the fluid drain into a pan. Check it out for any signs of wear or dirt.

After the fluid is out, take off the differential cover. Look at the parts inside, especially the bearing caps that hold the differential in place. Mark how they are positioned with a scribe or marker so you can put them back the same way.

Use a socket wrench to loosen and remove the bolts from the bearing caps. Once the caps are off, you can reach the differential assembly.

Gently pull the differential carrier out of its place. Check the ring and pinion gears to see if they are damaged or worn. Notice how the gears are spaced and how they touch each other; this helps when setting up the new differential.

Keep track of any small pieces like shims or spacers, as they are important for putting everything back together. Organize all the parts and bolts to make reassembling easier later.

Installing the New Differential

After taking out the old differential, get the new limited-slip differential ready. First, make sure it fits your Chrysler model by checking the part number against your vehicle's details. For a Chrysler 300, the differential must match the axle ratio and fit within the specified housing size in the service manual.

Check the new differential for any damage or defects. Use a micrometer to confirm that parts like the ring gear and pinion are the right size. Proper measurements are key for good performance and long life.

Add a good quality gear oil that works with limited-slip differentials, like synthetic 75W-90, to the gears and bearings. This helps reduce friction and heat when you first use the differential.

Place the differential into the housing and align it with the axle shafts. Tighten the differential bearing caps to the specified settings, usually between 60 and 70 ft-lbs. Use a cross-pattern to tighten them evenly and avoid any warping.

Proper installation helps the differential work better, giving you better handling and stability on various roads.

Testing and Adjustments

Make sure the new limited-slip differential in your vehicle works well and meets your needs. First, check that all parts line up properly and are tightly secured. Look for leaks or strange noises that might show something isn't right or is broken.

Take the car for a test drive in a safe place like a parking lot. Drive slowly at first to see if anything feels off. Then, go a bit faster and make sharp turns to see how the differential handles. It should spread power evenly without causing too much wheel spin or locking.

For more detailed checks, use a tool called a dynamometer. This measures how the power is shared between the wheels, giving you clear data on how the differential is doing. Compare these numbers with the ones from a well-working differential to see if everything is good.

If you find problems, make some changes. You might need to adjust the differential, tighten bolts, or realign parts. If issues don't go away, look at the manufacturer's instructions or talk to a professional. Fixing these things will help your car's transmission last longer and work better.
