ABS/Wheel Speed Sensors
 

I'm in the process of replacing the front sensors on my 1994 325is. I have removed the bolts but the sensors are very tight. As if they are seized in place. Is there an easier way to remove them, or does it just take brute force?

Dont just use brute force or you may break something. Use Penetrating fluid first, soaking it liberally. Then try it. Add a cheater bar onto your wrench for more leverage but go slow and dont force it.
