Rear Axle Dampers

Are you referring to two-piece weights that go around the middle of a half shaft or the rubber bumpers that bolt to the frame right over the axle to prevent it from banging metal-on-metal when it bottoms out?

If those were original equipment with the car the dealer will have them available unless the car is too old. Ford is good about discontinuing parts when they don't want you to repair your car, but buy a new one instead. You should also be able to find them at the auto parts stores. They might have to special order it if it's not something that is asked for very often. If this was an aftermarket add-on item you'll have to look for the original manufacturer of that part. Rancho Products makes a lot of steering and suspension-related parts to solve common problems. They also supply some parts to the car manufacturers. You might also look at other Ford products to see if they used that part and it can be adapted to your car. I looked at www.rockauto.com but didn't find any listing for the damper you want or the two parts I suggested. That doesn't mean they aren't out there. Depending on how long you need the damper to be, you might look at a steering stabilizer for a Jeep or Dodge truck. They are just like a regular shock absorber except they push together and pull apart equally hard in both directions.
