bmw x3: front drivers side wheel bearing going..wheel drive

Resolved Question:

I have a front drivers side wheel bearing going out on my BMW xi all wheel drive car. I would like to know if changing out this bearing requires the bearing to be pressed off and on? Also want to know what tools are required to do this job and if I can get a quick run down of the steps.....

The bearing DOES have to be pressed in; after removing the brakes and the front axle shaft, the wheel hub has to be pulled off using a slide hammer, then the bearing can be pressed out using a wheel bearing press tool, which has special sized cups that allow the wheel bearing to be pressed out and in.

 

You would have to purchase the correct sized cups that are specific to the bearing size, this will be costly, especially if they will be used for this one job. I would recommend leaving this one to a repair shop that has the tools.

 

I have provided you with the instructions for the bearing repair also:
