When do you need a new pinion seal?
When do you need a new pinion seal?
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. Replacing the differential seal can assure that your differential has plenty of fluid, which can help it last the life of your vehicle.
How do you replace a pinion seal on a front axle?
Using a chisel or a similar pointy object, tap the lip around the edge of the pinion seal (Figure 11) to dislodge it from the housing. Work your way around until the seal is completely removed from the axle housing. Put a light coat of grease around the outside metal surface of the new seal.
What causes a leak in the front pinion seal?
A common failure is the front pinion seal. The oil seal that goes around the pinion shaft (where the front driveshaft connects) in the axle housing will start to seep fluid. Eventually this seep will become a drip, and the drip will become a running leak.
Where is the pinion sleeve on a front axle?
The pinion seal will be in the housing, the pinion sleeve will be on the pinion flange. Both of these need to be replaced to properly fix this leak. Before you start changing the seals, be sure to clean any grease and dirt off the area around the seals. You do not want any debris getting into the new seal and damaging it.

What happens if a pinion seal fails on a differential?
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. A failed pinion seal can result in a minor leak where fluid seeps out, or a major leak that can ruin the differential bearings and gears.
How do you remove a pinion seal on a car?
Once the puller is in place and mounted, by slowly tightening the drive shaft it will begin pulling the flange/yoke off the pinion shaft. In most cases, continue driving the center shaft until the the flange comes loose and off the pinion shaft. Step 1: Set up a drain pan. Place a drain pan underneath the pinion seal area. Step 2: Remove the seal.
