How hard is

[Lake]

It to change a wheel bearing? I believe I need a new one and don't wanna start something I can't finish.

Do I need any special tools, or machines?

Car: 1985 BMW 325e

If you know of any tutorials please link them.

Thank you,:-P

Search, topic has been covered in the DIY section on how to replace both front, and rear, wheel bearings.

easy if you have the right tools. Usually no puller is required.

A front wheel bearing is pretty easy to change. You might need a puller for the inner race. The rear wheel bearings are easy with a B90 tool set and a real pain otherwise.

Front's are easy, rear can be a real PITA, even with the right tool. I had more trouble getting the axle back in the hub than anything else. Harbor Freight sells a FWD bearing kit part #66829 that makes it easy to get the bearing out.

I have seen a BMW special tool that makes getting the half shafts back in a piece of cake, but I have no idea where you'd get one now. And I have learned to very carefully examine the splines on the half shafts for any evidence of galling. If I find that, new half shafts and hubs will be used.

Heating the hub to about 250F and chilling the half shaft spines in LN2 (or in an alcohol & dry ice mixture) helps. The one thing that you cannot do without damaging the half shafts is to drive them in.

I did my front one and it was super easy but I have been doing auto repair from the age 13.
