I have a '87 745t that has been lowered using IPD springs and has Bilsteins. I have replaced the front bushings with urethane. I have also replaced the front wheels and tires and had the car aligned. When I am driving 60 - 75 mph and turn left I get a strong vibration that appears to come from the left front. Turning right is fine. Faster or slower the vibration is not noticeable. I thought it might be the front wheel bearing. I did not feel any play when I jacked the car up and grabbed the wheel. Since I have the updated hubs the dealer wanted $150 for the wheel bearings. I picked up two sets from a wrecking yard. After installing the replacement hub the vibration went away for about 600 miles. Now it is back. The spindle looked ok when I replaced the hub. Should I put the other hub on an cross my fingers or is there something else to check.
