How hard is it to replace pinion seal?
Fortunately, replacing a pinion seal isn't a difficult task and there are a variety of methods to successfully accomplish that. ... Like GM, we, too, must caution that the relationship of the pinion gear, pinion flange, and retaining nut must be exactly maintained so that pinion bearing preload isn't altered.
How serious is a pinion seal leak?
In this case total gear failure is imminent, and will definitely cause catastrophic failure. Even barring catastrophic failure, and the very least, with lack of fluid you will wear the gears and bearings out way faster, and will generally cause the differential to “howl” especially at highway speeds.
How much does it cost to replace a pinion seal?
The average cost for a Pinion Seal Replacement is between $229 and $276 but can vary from car to car.
What would cause a pinion seal to leak?
As the rubber on the pinion seal wears down, the pinion seal's functionality is affected. It starts becoming less and less effective and cause leakages. For this reason, you should check the pinion seal every time you schedule your car for maintenance.
What does a pinion seal do?
The pinion seal, also called a pinion shaft, is designed to keep oil in and any water, dirt or debris out. ... 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.
What happens if you run out of differential fluid?
If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
How long does it take to replace differential seal?
According to most service manuals, the job of replacing the differential output shaft seal may take anywhere from 3 to 5 hours to complete.
How much does a pinion bearing cost?
Q: How much does it cost to replace a pinion bearing? The replacement of a pinion bearing would cost an average of $239 – $286. Parts are estimated to cost about $66 – $68, while the labor costs would be around $173 – $218.
What does a bad pinion bearing sound like?
If both the ring and the pinion go bad, the sound will be pretty intense when the car accelerates. The sound is a loud howl or a whine. That sound is a clear indication that the ring and the pinion are both worn. In some cases, you can notice the sound only when the car is at a certain speed range.
How long does a pinion seal last?
In terms of lifespan, there's no set duration for a pinion seal. Really, they last as long as they last. There are many different factors that come into play here. All seals will degrade with time and exposure to differential fluid, but your driving habits will have a significant impact on lifespan.
Why is my rear end leaking?
Rear Differential Leak – more commonly, the problems stem from low rear differential oil. Rear differential leaks are the culprit, either at the axle seals, the pinion seal (where the driveshaft attaches), or the rear differential cover.
What causes a ring and pinion to go bad?
Possible Cause #2: Worn carrier or pinion bearings can create excessive play between the gears and produce an uneven wear pattern or chipping teeth. Check for worn bearings and replace as necessary. ... Possible Cause #4: Improper break-in will lead to premature wear.
