A Driveshaft on a Porsche or any other car is one of the most critical components of the vehicle outside of the engine and transmission. With a high-performance car like the Porsche, any damage to the driveshaft or its support system will be felt right away. In this article, we will tackle how to identify driveshaft support failure in a Porsche and how to deal with it.
The Function of the Driveshaft and its Support System
Before we discuss how to spot driveshaft support failures in a Porsche, we must first understand the purpose of the driveshaft and the support system.
A driveshaft on a Porsche acts as the muscle if you will of the car. The driveshaft takes power from the Porsche’s engine and transmission and transfers that power to the wheels of the car. Since the drive shaft rotates at fast revolutions, it needs a solid support system to keep it from moving.
Symptoms of a Failed Driveshaft Support System
Porsches have installed a center driveshaft support system, whose job it is to keep the driveshaft stable. Without the support system, the driveshaft could become unbalanced and break underneath the car. Here are a few signs that your Porsche’s driveshaft support system may be failing.
- Grinding, clunking, or scraping sounds that are coming from underneath your Porsche may be coming from a failed driveshaft support system. The support system acts as a bearing for the driveshaft. When its components break down, they will make the same sounds of a bad bearing going out.
- When placing your car in gear or taking off, jerking motions can be caused by a poor driveshaft support system. The driveshaft needs to spin with the shaft as straight as possible. If the support system fails, it can allow slack in the driveshaft that shows up as jolts to your car.
- Broken drive shafts may occur if the support system has failed. If the driveshaft on your Porsche breaks, you will find yourself stranded wherever you are.
- Burning smells from components that have been damaged or worn prematurely, and overheating can produce a strong burning smell. If you have burning odors coming from anywhere on your Porsche, it is a good idea to have it checked out immediately.
Why do driveshaft support systems fail?
There are a few reasons why a driveshaft support system could fail. Let’s take a look at some of the reasons.
- Damage: With the driveshaft located under the Porsche’s undercarriage, the driveshaft and its components are at risk of damage from road hazards. Boards, blown tires, and other debris are found on our highways. If some of these objects are in your path while driving and strike under your car, they could cause damage to the driveshaft and support system.
- Lack of Maintenance: Some will tell you that normal wear and tear are a reason for a failed driveshaft support system. This is partially true, but the root cause is, in reality, a lack of regular maintenance. Professional technicians who are trained to work on Porsches know what to look for during an inspection and correct any issues before they arise. Many owners think they are saving money by skipping regularly scheduled maintenance but will pay for it in the end with high repair costs.
- Defect in the Design: Although Porsches components are usually designed for a precision fit, it is still possible to have a defective driveshaft or support system that slipped through a quality check during installation. This is another reason to have certified technicians service your Porsche on a scheduled basis to find any issues that can cause problems later.
