1. You must buy new bearing bolts as they are stretched during installation. 3. There is 2 kinds of thread for this bearing. Make sure bolts fit beforehand. M12x1.5x45 vs M12x1.25x45. 4. Removing the strut from the knuckle is some work. There is special tool to open up the knuckle. Use rubber mallet if needed. 5. Once you torque bearing bolts to spec, you need to do additional 90 degrees. Use sharpie to mark your target angle. 6. You also need to replace strut pich nut
I’ve done this job on my 6 series and can here humming now from front. I torqued it to the correct spec but didn’t build it up from low torque then a round a high torque. Could this be an issue? Thanks
