The output shaft seal is a vital part of your car’s transmission or transfer case, but it can be a little complicated. You feeling up for it? Let’s go.
The output shaft is a rotating assembly that serves the purpose of transferring power from the engine to the drive wheels. And yes, that is exactly as important as it sounds like it is. Your car needs it.
The output shaft seal is a barrier for the seal, preventing things from escaping or entering. Thanks to the seal, fluid from the transmission or transfer case stays contained in the system, while dirt, dust, and debris is blocked from entering. Think of it like the bouncer at the club the night you forgot to bring your ID. Sorry for bringing up a bad memory.
The type of car you have impacts where the output shaft seal is located. In a car with rear-wheel drive, the output shaft seal is located on the transmission extension housing. In a front-wheel drive car, the output shaft seal (also known as the axle seal in this case) is placed where the CV axle is connected to the transaxle final drive assembly.
In cars with four-wheel drive, you’ll find an output shaft seal where both the front and rear driveshafts are connected to the transfer case. And in an all-wheel drive transfer unit, one seal is located where the CV axle meets the transaxle, and another where the CV axle meets the power transfer unit.
I know that was a lot to take in, so just trust me when I say that the output shaft seal is very important, okay?
Cars can get a lot of leaks because cars have a lot of fluids. Pretty simple. And leaks are almost always a sign that something is wrong and needs repairing or replacing. If your car has a busted output shaft sensor, you may end up leaking transmission or transfer case fluid. You can probably do the math on whether or not that’s a good thing. Always keep your eyes out for leaks..
You guessed it. If your transmission or transfer case fluid is leaking, then you may find your car low on those fluids. You’re probably not popping the hood and checking out your fluids on the daily, but you know what? It wouldn’t hurt to take a look once in a while. It’s a smart idea to regularly check on your car’s fluids, and make sure everything is at a good level. If you find that the transmission or transfer case fluid is low, well, time to call your old friend the output shaft seal, and see if they have a good alibi.
Let me paint a very basic scenario for you: You’re driving your car, and suddenly the transmission or transfer case isn’t working well. A broken output shaft seal means your transmission or transfer case won’t have enough fluid, and that leads to those units not performing properly. You’ll notice it when you drive, and if you’re thinking straight you’ll realize that diminished performance needs to be addressed immediately.Get a Quote 12-Month | 12,000-Mile Warranty
Do I need to spell it out? Your transmission is vital. Your transfer case, if you have one, is vital. You don’t want either of those systems to be struggling.
If your output shaft seal is busted, then your car’s transmission or transfer case will feel the impact. And if you ignore it long enough, irreparable damage will be done to the transmission or transfer case, and then you and your wallet are really in for a surprise.
