914World.com _ 914World Garage _ Front wheel bearing get loose too often

Posted by: second wind May 29 2017, 11:09 AM

Happy Memorial Day.....my wheel bearings seem to loosen up far too often. I replaced less than 30,000 miles ago and when i tighten them back up I allow wheel to spin freely but with a touch of drag. Any thoughts on what is going on? Thank you!

Ft wheel bearing should be the most maintenance free item on your car. . really can't loosen up except for ball / race wear or if the pinch nut wasn't tightened properly .
Since you said you replaced the bearings recently, how sure are you that you fully seated the new inner race. . . ?? that's the 1st place to look. . then clean the bearings and look for obvious wear. . do both side do the same

Please discuss "pinch nut tightened properly". Maybe I am not tightening against the bearing enough? Thank you very much!

The front wheel bearings will loosen up with hard use. We used to see that all the time at autocrosses--about once a season, the 914s would need their front wheel bearings re-tightened.

The spec for the bearings is literally "tight enough that the washer behind the nut can just barely be moved with the tip of a screwdriver."
