How to Diagnose a Bad or Failing Pinion Seal?

pinion

The pinion seal is located inside differentials of vehicles. The pinion seal is located near the pinion shaft and is designed so that fluid does not leak out of the differential. Some vehicles have a rear pinion seal, where others have both a front and rear pinion seal, it just depends on the make and model of your vehicle and if the vehicle has rear or four wheel drive. Over time, the rubber on the pinion seal wears down and the seal will not be effective as it was before. Each time your vehicle is serviced, the pinion seal should be inspected to ensure there are no symptoms of a bad or failing pinion seal.

1. Leaking pinion seal

One of the biggest signs your pinion seal is failing is it is leaking. To check for a leak, follow the drive shaft to the rear axle, then look around the yoke for fresh oil. If you notice fresh oil, you have a pinion seal leak. As soon as you notice this, contact the professionals at YourMechanic to have the pinion seal replaced.

2. Differential has low fluid

If you notice your differential has low fluid, chances are it is leaking from the pinion seal. This needs to be fixed in a timely manner because as the fluid levels drop, the gears will wear down as the friction increases. Without a proper working differential, your vehicle will not be able to be driven. Furthermore, a pinion seal is a relatively straightforward repair, but if you wait too long, it will become more extensive once you start adding in various parts such as the differential.

3. Whining noise

Low fluid in the differential is normally shown by a whining noise while the vehicle is in motion. This noise could mean a pinion seal leak, or it could be another problem with your vehicle’s differential. A professional from YourMechanic will be able to diagnose the problem and have your vehicle repaired in a short amount of time.

As soon as you notice a leaking pinion seal, constant low fluid in your differential, or a whining noise while you are driving, book a service online 24/7 with YourMechanic to have your pinion seal looked at. This is an important part of keeping your vehicle properly maintained and running correctly. In addition, by repairing the problem early, you will be able to save your differential which can save you time and money in the long run.

Breck was sent as a replacement mechanic for my original morning booking that was a no show. He arrived on time, with all tools and parts needed for the job. Unfortunately, he was unable to get authorization for additional parts and was forced to spend a very long time on the phone to get authorization to update my quote and purchase an additional part for the job. He did not have everything needed at first (he was covering last minute for thr no show), but he got things squared away quickly. He is very bright and professional, and answered all my questions thoroughly. His customer service skills are excellent. Unfortunately the company was horrible. They are very difficult to contact, and I know this because I spent over an hour.on hold with them to get to a representative. Once I got someone, they were helpful. It was December 26th, so I can understand being understaffed, but had this been an urgent repair, I would have been in trouble. Breck made the entire service a pleasure. If only they would stock their mechanics better, he would have completed the job much sooner. He stayed as long as it took to get the job done, and let me take a test drive before I even had to pay! I would only use your mechanic.com ever again because Breck is one of their finest mechanics.

Braxton - Showed up on time as scheduled and completed the job in 1 hour and 30 minutes verse the 2 hours quoted. He waited while I did a short test drive to confirm the seal didn't leak. Would recommend Braxton and will call for him for other needs in the future.

Chris was prompt - he's close to where I live. He knew what he was doing and assured me he had enough experience with pinion seal replacements - mostly Chrysler. Basic job is similar on most rwd vehicles anyway. He was prepared, ready and got done quickly and systematically. Also had friendly dogs with him, a very healthy Pit and maybe a Yorkie. I will be sure to request should I need more services in the future. The dogs can come, too.
