How to Replace Your Axle Tube Seal
The axle housing of your car is filled with fluid for the sake of gear lubrication. The gears turn the axle shafts regularly as your vehicle moves around, resulting in loads of friction as well as wear and tear. This necessitates a reservoir of lube to counter the grind. Once your axle seals that hold the axle fluid starts to fail, your automobile will leak grease out of it, making your car, jeep, or SUV run dry. With that said, here's how you go about replacing axle seals.
What You'll Need
- Needle-nose pliers
- Mechanic's wire
- Seal puller
- Gear oil
- Drain pan
- ?-inch ratchet and socket set
- Tire iron
- Wheel chocks
- Jack and jack stands
Step 1:Go to the front wheels of your vehicle and put the wheel chocks around them. Use your jack to lift the axle off of the ground then get the jack stands underneath the axle for good measure.
Step 2:Take off the rear tires with your tire iron then put a drain pan under your axle. On the back of the axle, there's a differential cover you have to unbolt with your ?-inch ratchet and socket so that you can drain all the oil into the aforementioned drainage tray.
Step 3:Use the same ?-inch ratchet and socket to unbolt the brake caliper from its axle and hang the caliper with mechanic's wire to avoid kinks and twists on the brake line. Manually slide off the brake rotor from the axle shaft.
Step 4:Get the ?-inch ratchet and socketonce more to unbolt from the center of the pinion the pinion shaft. Get the needle-nose pliers to assist in the removal of the C-clip and the axle's center. After all that's done, pull the axle shaft out of its housing.
Step 5:Utilize the seal puller in order to cleanly remove the axle seal from the axle housing as well. Then you can put on the replacement seal by tapping it into the housing with your mallet. From there, reinstall the axle shaft into the axle housing.
Step 6:You'll also need to put back the C-clip on the axle shaft using your needle-nose pliers and the pinion shaft plus pinion shaft lock bolt using your ?-inch ratchet and socket. Also, don't forget to reinstall the differential cover with the ?-inch ratchet and socket.
Step 7: Slide your brakes carefully onto the axle shafts by hand and bolt your brake calipers unto the axle with your ever-reliable ?-inch ratchet and socket. Fill your fixed and sealed axle with a fresh supply of gear oil then reinstall the fill plug.
Step 8:Lower your vehicle off of the jack stands then observe it for a little while to see if there are still any leaks left or not.
Installing a new axle tube seal after the original one has been worn entails taking apart your axle and rear brake assembly, accessing and removing the compromised seal, hammering in a new seal, and then going in reverse order in reinstalling everything from the axle shaft to the brake calipers. A compromised shaft seal will result in oil leaks, loss of lubrication, and the wearing down of your axle-related car components.
