Buying Your Car a Differential Gasket
Installing a new differential gasket will save your car's differential gear from leaks. While it is also true that you can use RTV (room temperature vulcanizing sealants) to fix the leaks, it's still better to replace the old and worn-out gasket as a long-term solution.
What are the materials used for differential gaskets?
Gaskets are usually made from sheet materials. This is the case with differential gaskets that are built out of gasket paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymer. The best differential gaskets not only provide good compressibility and adaptability, but they are also resistant to both temperature and chemicals, making these gaskets last longer. Therefore, you have to get one that has these good characteristics or features.
Differential gaskets are also made from a material that is to some degree soft and one that can bend such that it can be flexible and can snugly fit the space it is designed for, including any slight irregularities. There are many differential gaskets to choose from in the market. Prices of these gaskets range from $50 to $100. We recommend that you compare prices before making a purchase.
What are other things to consider when buying a car differential gasket?
Differential gaskets also work best with gasket sealants. These sealants are directly applied on the gasket surface. This will make the whole process less difficult because gluing the differential gasket to the part keeps the gasket from moving. Custom-made gaskets are also available. They use silicone for these.
6 Easy Steps to Replace Your Rear Differential Gasket
So you spotted a leak in the rear part of your car. This might just mean that the gasket that is between the rear end might have already cracked. Every time you remove the car cover, you also need to install a new gasket. Read on and learn how to replace your damaged differential gasket.
Difficulty level: Moderate
Tools that you'll need:
- Brake cleaner
- Gasket scraper
- Sealant compound
Step 1: Use the gasket scraper to clean the old gasket material off both the differential casing and the differential cover. Make sure to be careful enough not to scratch or damage the surface.
Step 2:Remove any remaining oily residue by spraying some brake cleaner on the scraped areas. After this, wipe it clean with a rag or paper towels.
Step 3: Smear sealant compound all the way around the track in the differential cover. Apply only enough amounts and make sure to get it around each bolt hole.
Step 4: Place a coat of sealant compound working it into the track around the edge of the differential cover. It helps to use small circular motions with your finger. Put back the differential cover onto the differential housing. Next, secure bolts back into the differential cover.
Step 5: Twist the bottom bolt tightly. Afterwards, twist down the top bolt then the bolt to left of the bottom one, and then the bolt directly across from that. Keep it up until all the way around the differential cover until all bolts have been tightened.
Step 6: Check below the car to see if there are any leaks coming from the gasket area. Go for a short distance test drive. Leaking would mean that the rear end bolts are not tight enough or the gasket is not properly installed.
Replacing your damaged differential gasket can take about 30 minutes to an hour. Installing it is not as tricky as it seems. It will help to know the specs of your vehicle, though.
