A Quick Guide on How to Remove and Install an Input Shaft Seal
It is important to inspect your input shaft seal for any seal fragments and heat damage. You will know if it is heat damaged when the seal is brittle and not pliable. Also, make sure that when you are going to install the input shaft seal, do not use a socket because you won't be able to control the seal installation depth. This will possibly cause a leak. Here's how you can remove and install an input shaft seal.
Things you'll need:
- Triple square driver
- Clean cloth or rags
- Small screwdriver
- Input shaft seal installer tool
Step 1: You need to place a drip pan on the floor to catch the oil that might leak.
Step 2: Carefully disconnect the return line from the steering gear.
Step 3: After that, you need to plug the return line. Cap the return port with high pressure fittings.
Step 4: Now, carefully disengage the intermediate column from the steering gear input shaft.
Step 5: Remember to clean the input shaft end, and remove all the dirt and water seal from the steering gear.
Step 6: Remove the spiral retaining ring by inserting a small screwdriver into the notch at the end of the ring. Make sure to do this carefully to avoid scratching the bore with the small screwdriver.
Step 7: Put back the intermediate column into the input shaft with the pinch bolt (installed but not tightened).
Step 8: You can put and tie a clean towel around the shaft area to reduce the oil leak.
Step 9: Do not forget to check the reservoir and top up the fluid if needed. Always choose a high quality fluid for your vehicle to experience better performance. If you will use any unapproved fluid foryour vehicle, it will eventually lead to leaks and deterioration of the input shaft seal. This will cause loss of fluid, and will soon result in a loss of power steering assist.
Step 10: Make sure that your vehicle is in neutral gear, and try to turn the starter momentarily. If you notice that the engine starts, turn off your vehicle immediately.
Step 11: Remove the towel, and disconnect the intermediate column.
Step 12: You can now remove the input shaft seal.
Step 1: Coat the inside diameter of your new input shaft seal with the grease that is provided in the kit.
Step 2: Carefully place the end of the input shaft seal installer tool over the input shaft (against the seal. Tap the tool until the shoulder of the tool is right against the valve housing.
Step 3: Check if there is any debris in the retaining ring groove and the sea bore.
Step 4: After ensuring that there isn't any debris, carefully insert the new retaining ring into the groove.
Step 5: Coat the end of the valve housing bore with grease.
Step 6: Put some more grease at the backside of the new dirt and water seal.
Step 7: You may now install it over the input shaft by placing it in the groove just behind the serrations and against the valve housing.
Step 8: Now, you need to connect the intermediate column again, and tighten the pinch bolt to the torque that is specified by your manufacturer.
Step 9: Connect the return line again to the steering gear return port.
Step 10: Check the fluid level, and top it up if needed.
The entire process might take you an hour and a half to two hours depending on your DIY skills. Always refer to your manual for more detailed information on how your input shaft seal works.
