Frequently Asked Questions (FAQs)

1. How do I know if my rear differential bearings are bad?

Signs of bad rear differential bearings include regular clunking noises, a howling noise from worn-out bearings, and rumbling while turning, which can indicate bad wheel bearings. These symptoms suggest that the bearings are not properly supporting the gears and may need to be replaced.

2. How much does it cost to replace diff bearing?

The cost of replacing differential bearings and seals can range from $400.00 to $650.00. However, if the issue is with the transaxle, the cost can be twice as much. It's best to consult with a professional to get an accurate estimate for your specific situation.

3. Can you drive with bad differential bearings?

In most cases, it is not recommended to drive with bad differential bearings. However, there are rare situations where it might be possible, such as in a simple four-wheel-drive car with no torque vectoring and a completely stripped input gear into the rear differential. It's important to assess the specific circumstances and consult with a professional before attempting to drive with bad differential bearings.
