Is it still an issue?
I did mine after 200 miles. You can tell the bearings got hot. Did another car and same deal. Cheaper to do it, be done with it, rather than pounding on bearing races and replacing worn out stuff.
Guys will spend $1k on a tuner and clutch kit, $1k on A Arms, $1k on radius rods, etc etc.. But don't want to buy a tool for $40ish and put some grease in the hubs for peace of mind?
Some guys have had issues, some haven't, it's just insurance for the bearings...
