Porsche 944 Turbo Rear Wheel Bearing Replacement (1986 - 1989) 

Please note: There are several inaccurate steps within this article, please only use as a basic guide and DO NOT follow step-by-step.
If you are starting to hear a high pitch wine, like a jet taking off, from the rear end of your 944, or your 944 has over a 100,000 miles on it you should inspect your rear wheel bearings for replacement. The bearing supports the full weight of the car both while stationary and under load. While 944 rear bearings are known to last a long time, as the mileage increases on the car, the bearing will eventually fail. Replacing the rear bearing can be a trying and difficult job depending on the state of the car. You will have to commit to the job, as you will be destroying some old parts in removal and will not be able to use the car until the new ones are installed. Make sure you have everything you need before you start.
Before you begin the job place the new bearing in the freezer, preferably over night if you can. Freezing the bearings will decrease the outer diameter and make installation into the hubs easier.
You will need to first remove the brake caliper, rotor and axles. Please see our articles on these procedures for further assistance.
