Choosing the Right Output Shaft Seal for Your Car
An output shaft seal, or what is also called an axle shaft seal, is the seal located between the driveshaft, and transmission panel. It is a circular disk designed to keep transmission oil from leaking onto the driveshaft.
How does it work?
Shaft seals are used in order to prevent transmission oil from leaking onto fragile car parts. This car part serves as a barrier in pumps to separate liquids, and confine pressure with its spring mechanism. The output shaft seal can be found in the underside of the driver, or passenger seats of the vehicle.
When to replace an output shaft seal?
If you see transmission oil leakage around the driveshaft, then your output shaft seal may be broken. However, these are confusing symptoms because oil leaks can still occur even if the output shaft seals are working properly. One of the reasons for such problems is a worn out output shaft seal bearing. If the bearing gets damaged, the output shaft seal becomes vulnerable to leaking. Whether you use a 5-speed or 6-speed manual transmission, the shaft seals are basically the same. The only difference lies in the design, and the tools used to install the seals. For vehicles with automatic transmission, the color of fluid leak should be pinkish, while Cars with standard transmission may expect clear liquid leaks.
While there are differences between the two shaft seals, the process used to replace the seals are the same. The procedure can get messy and you can either repair it by yourself or hire a mechanic to do the job for you. It is better to read your car manual, or call technical support to gets answers for your questions. Lastly, have experts inspect your car for fluid leaks every few months to ensure that your car runs smoothly.
Output Shaft Seal Replacement in 6 Easy Steps
Problems with transmission and oil leakage on the driveshaft area are usually associated with broken, or worn out output shaft bearings. A damaged output shaft bearing in turn, entails replacing the output shaft seal altogether. The output shaft seal is a stainless steel cap that prevents transmission oil from leaking onto the driveshaft assembly. A common problem for buyers of output shaft seal replacement parts is that it tends to get damaged easily once the output shaft bearing leaks. To save up money from maintenance and repair costs, replace those leaking output shaft seals right away. Luckily, we created this comprehensive guide that will help you replace your output shaft seal in just 6 easy steps.
Difficulty Level: Difficult
Tools you'll need:
- Jack stands or wheel ramps
- Crow bar
- Output shaft replacement
Step 1: Place jack stands on the rear wheels, and locate the output shaft assembly in the center of the chassis. Raise the clearance with the jack stands or wheel ramps depending on what's available at your disposal.
Step 2: In order to remove the output shaft seal, you must first remove the driveshaft using a crowbar. Pry the upper end of the driveshaft down connecting it to the chassis, and let the spring contract in the middle until it can safely be removed.
Step 3: Once the driveshaft has been removed, clean it up using a clean piece of cloth damped in rubbing alcohol, and apply grease afterwards.
Step 4: Remove the output shaft seal using a screwdriver and a hammer. Chisel it out by inserting the flat-tip of the screwdriver onto the side of the seal. Once the flat-tip has been inserted, pry it outwards.
Step 5: Grease up the new output shaft seal, and install it onto the output shaft. Return the cleaned driveshaft by screwing it back to place, and using the contracting springs to insert it without breaking.
Step 6: Secure the driveshaft snugly, remove the jack stands, and go for a steering test to see if the new seals are leaking or not.
Replacing the output camshaft seal can be a risky task even for the expert DIYer. Before going on with the procedure, consider hiring a pro mechanic or ask a hot-rod auto-repair junkie to help you out. The entire procedure can take from 1 to 2 hours for beginners, and up to an hour for most DIY experts.
