Frequently Asked Questions (FAQs)

1. How long do axle seals last?

Axle seals can last the entire lifespan of a vehicle if not damaged or contaminated. They require no maintenance and only need to be replaced if they become damaged. Signs of a failing axle seal include low transmission or differential fluid.

2. What type of wheel bearings are commonly used on solid rear axles?

Solid rear axles commonly use ball bearings and straight roller bearings for the wheel bearings. Since thrust is not a significant concern at the rear wheels, these types of bearings are suitable and may require regular repacking.

3. How many axle seals does a car have?

Each vehicle has an axle that transfers power to the wheels. The number of seals on the axle can vary depending on the vehicle, but typically there are two to three seals present.

4. Can you drive a truck with a bad axle seal?

If there is a small leak, you may be able to drive for a short period of time. However, driving with a leaking axle seal can cause permanent damage to the transmission. The axle seal connects the driveshaft or CV axle to the transmission or rear differential.

5. How much does it cost to replace axle seals?

The average cost for replacing an axle shaft seal ranges from $250 to $305. This cost includes labor and parts, with labor costs estimated between $210 and $265, and parts priced around $41.

6. What type of bearings are used in the rear differential?

In the rear differential, front and rear pinion bearings and carrier bearings are commonly used. Pinion bearings reduce friction in the desired movement direction, improving efficiency and ensuring smooth operation of the smallest gears in the differential.

7. Which is the most commonly used type of bearing for automotive wheels?

Ball bearings are one of the most commonly used bearings in automotive wheels. These bearings can handle both radial and axial loads, allowing for speed changes and minimizing friction between two surfaces.

8. What happens when an axle seal goes bad?

When an axle seal goes bad, it can lead to fluid leaks, particularly during highway driving. The transmission fluid level may drop, causing slipping and potentially permanent damage to the transmission if not addressed in time.

9. How much does it cost to replace a transaxle seal?

The average cost for replacing a transaxle seal is similar to the cost of replacing an axle shaft seal, ranging from $250 to $305. This cost includes labor and parts, with labor costs estimated between $210 and $265, and parts priced around $41.
