What is a pinion shaft seal?
The pinion seal, also called a pinion shaft, is designed to keep oil in and any water, dirt or debris out. As long as the pinion seal is in place and performing well, the differential will stay in good shape and operate as it is supposed to.
What is the purpose of pinion shaft?
A pinion shaft is the main drive member of most gear train assemblies. The shaft transfers the input of a drive shaft or crank to the rest of the gears to produce the work for which the gear train is designed.
What is a input shaft seal?
Shaft seals for all types of transmissions Transmission shaft seals are used for the input and output shafts of all types of drive-line units including transmissions, transfer cases, Rear Drive Modules, Power Transfer Units as well as hybrid and e-Drive units.
Where is the pinion shaft seal?
The pinion shaft oil seal is located in the differential. The purpose of the seal is to keep fluid in the differential, so it can stay lubricated and run properly. The pinion shaft oil seal is located behind the pinion flange, which is what attaches to the driveshaft flange.
What does a pinion seal leak look like?
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.
How much does it cost to fix a pinion seal?
between $230 and $277

What is an input shaft?
Inside the transmission, an input shaft is connected with the engine, which turns the shaft; while an output shaft sends its spinning motion toward the vehicle’s wheels to turn them. The input shaft’s power drives a set of gears, called the countershaft gears.
Where is the output shaft seal?
The front output shaft oil seal is located on the front of the transfer case on a four wheel drive vehicle. It seals the oil into the transfer case at the point where the output shaft meets with the yoke for the front driveshaft.
What is a pinion shaft?
A Pinion Shaft is a round rod that has teeth on it (although these teeth run parallel to the length of the shaft) and is an external input shaft of certain gear operators, which drive the internal reduction gearing. Pinion shaft can be of several types like Integral & Shrunk fit Pinion Shafts.
Where is the pinion seal on a Ford Ranger?
A pinion seal is located in the differential and prevents fluid leaking out past the pinion shaft. You may need a new pinion seal if you hear a whining noise while driving, or if you notice leaks or low fluid in your differential.
