Has anyone experienced excessive play in a newly installed rear wheel bearing? During the restoration of my 72 I installed new bearings. The left rear has no play and the hub rotates smoothly. The right side seems to have excessive play and with the car on the lift I can wiggle the tire and wheel left and right about 1/8th of an inch. Thinking I might have damaged the bearing during install I ordered another one. Yes I bought decent quality from Pelican and not a made in china cheapie. Again I carefully pressed in the bearing feeling confident it was not damaged but once again the hub rocks while the other side doesn't. Thoughts?

Here's my theory on why the boxster guys have trouble with the bearings while most of us do not. I think the brand new bearings are filled with a bead of grease from a machine instead of having grease worked into the bearing retainer. The boxster spec cars are getting used on the track. So the guys take out there cars and immediately start driving some hot laps. This sudden increase in speed doesn't give the bearing much chance to warm up slowly so the grease can soften and flow to the bearings. So for at least a while, there is hot metal on metal. The bearing gets trashed before it ever has time to get lubricated. Most non track cars would be driven slowly for a while and the grease has time to warm up and flow around the bearing before any one part gets too hot.
The boxster guys are not modifying the bearings, just making sure they are completely lubricated. just a theory... |
