Install a Summit Differential Cover

Differential covers keep the gears and oil inside a vehicle's rear end. Older vehicles use a differential cover with no drain or vent plugs. This makes it necessary to remove the differential cover each time you perform a rear end oil change. Summit Racing differential covers are made from lightweight aluminum and have the plugs required to change oil without removing the cover. This saves time and money when you need to change the oil in your rear differential.

Procedures:
1. Apply the vehicle's parking brake. Set a wheel chock under each of the vehicle's rear wheels.
2. Set a drain pan under the differential housing. Remove the bolts from the differential housing cover with a socket matching the bolt heads attached to a 3/8-inch ratchet handle. Allow the oil to drain from the housing for five to 10 minutes.
3. Scrape the old gasket from the cover mounting flange of the differential house with a metal putty knife. Spray aerosol brake cleaner on the flange. Wipe the flange with a clean rag to remove remaining debris and oil.
4. Apply RTV sealant to the flanges of the Summit differential cover and the differential mounting flange. Press a differential gasket into the sealant, which is on the differential cover flange. Push the cover onto the differential flange.
5. Thread the differential cover bolts through the Summit differential cover and into the differential housing. Tighten the bolts with the socket and 3/8-inch ratchet handle.
6. Remove the top fill plug from the Summit differential cover with a 3/8-inch ratchet handle.
7. Cut the ends off the nozzle of a differential oil tube. Pour the oil into the differential. Repeat the process until the oil level reaches the bottom of the fill hole. Install the fill plug into the Summit differential cover.
