Porsche Vibration Repair

Porsche Vibration Repair

In my opinion, Porsche makes one of the nicest vehicles on the road today. But there’s nothing worse than driving one that has squeaks, noises, and vibrations. We saw one today where the customer was concerned about an aggressive vibration when accelerating. While there are many things that can cause this issue, this one was pretty simple to identify. Today I’ll tell you about this Porsche Vibration Repair, what happened, how it happened, and how you can prevent it from happening to you.

You can see from this picture that the housing for the bearing support is just hanging on the shaft. It’s not connected to anything.

Porsche Vibration while accelerating

This customer’s concern was a vibration while accelerating. The back story is that he called a few other shops and went to one that wanted him to replace the front brake calipers (spoiler alert, the brakes and calipers are perfect). The first step for any customer concern is to first verify it. This is done with a simple road test by one of our Master Technicians. In this case when accelerating normally the vibration was so violent that it felt like someone was under the vehicle hitting the bottom of the driver’s seat with a hammer. The next step was to put the vehicle up in the air to take a look and inspect for the exact cause of the vibration.

The Technician checked all of the tires, brakes, suspension, and drive line. While most everything was in great shape it was obvious that there was a problem with the drive shaft. A drive shaft is a rotating shaft that transmits torque in an engine. More simply put, when you step on the gas pedal the engine turns, the engine turns the transmission, the transmission turns the drive shaft, the drive shaft turns the gears that make the vehicle move forward or backwards.

On this Porsche Cayenne the drive shaft is pretty long so in the center of it there needs to be a support to hold it tight while rotating so there is no vibration. This support is called a “Carrier Bearing”. The carrier bearing just sits in the center of the shaft and the shaft rotates through the center of it.  There were a few problems here.

First, the customer recently purchased the vehicle second hand. The drive shaft in the vehicle was replaced somewhat recently with a used part from a junk yard. This was obvious due to faulty installation, missing bolts, and yellow writing all over the shaft indicating a stock number from a junk yard. The second issue was that the bearing wasn’t just faulty, it was completely destroyed. It literally wasn’t connected at all. So when the drive shaft would spin to turn the wheels, it would vibrate and essentially hit the floor of the vehicle causing the aggressive vibration felt while driving.

The repair was actually pretty simple. Since the carrier bearing is part of the drive shaft and has to be purchased as one unit, we simply removed the old shaft and installed a new one. While putting the new one back up, we installed any and all missing hardware to ensure this one lasts. The total repair took a little over an hour and the customer had the vehicle back the following day because we had to order the part.

After the repair we took a second road test with the vehicle to be sure that the vibration was gone. We’re happy to say that this Porsche Cayenne Repair fixed the issue and the vehicle is back to

rolling down the road as smooth as silk.

How can you prevent this from happening to you?

The reality is that if you drive a vehicle, things wear and eventually break. If a vehicle sits and doesn’t get driven, things break down and need replacement. In this case the bearing was pretty bad. On a scale of 1-10 (10 being the worst) this bearing was about a 12. There was nothing left to it. Which leads us to believe that there was a significant noise and smaller vibration for a while before the bearing came completely apart.

The first step towards preventing this level of failure would have been to have the vehicle properly inspected by us prior to purchase. Whenever buying any used vehicle you always want to have a trained and impartial set of eyes check it over for you to spot any apparent problems or anything on the horizon (like a faulty drive shaft….). Our Technicians see Porsche Repairs all the time so it’s  very easy for us to spot common problems before they fail.

This is how the bearing should look without the bracket in place.

The next option is to have your vehicle serviced regularly. I say it all the time, “Scheduled maintenance is the key to avoiding costly and unexpected break downs.” By following the service schedule for your vehicle we would see your vehicle roughly every 3-5,000 miles. During each of those visits the vehicle gets a full 55 point inspection for FREE. This inspection is specifically designed by our staff to spot safety and mechanical issues before they cause major issues or put you in harm’s way. If we had seen this vehicle, we most definitely would have seen this so that the customer would have time to prepare and budget for the repair.

In this case since it was unexpected and the part was pricey, he took advantage of one of our Payment Plans. Approval took about 10-15 minutes and he had the funds available the same day. His repair is also backed by our 2 year, 24,000 mile Nationwide Warranty and 12 months of Roadside Assistance at no additional cost. This customer can rest easy knowing that he received a quality Porsche Repair and peace of mind at a fair price that he can pay for over time.

Precision Auto Repair and Sales West Springfield MAI’m new to Porsche ownership. I always wanted one and finally had a chance to get my dream Porsche Cayenne. When I had this issue I just din’t know where to turn. Some co workers recommended James so I gave him a shot. I was not even slightly disappointed. They got my baby in right away and had the issue pin pointed in a few minutes. The pricing was very fair and the financing was a breeze. I got 0% for 6 months, my car back the next day, and they even washed it for me. I’ll most definitely be returning for future service here. Great job James and staff. My family and I are very appreciative.
