I drove home yesterday hearing a high pitched squeal coming from the left front wheel area. Mainly heard while driving straight above 20 mph and in left turns. Changes pitch in the turns and over bumps. The left front wheel was hot to the touch when i parked. I pulled the wheel and outer bearing for inspection. Grease appeared as new with no burnt smell and no dripping. Using Valvoline synthetic disc brake bearing grease.The bearing looked fine with no discoloration or marks. If anything the adjustment seemed a little tight so I repacked the bearing , re-adjusted and put it back on the road. Same noise today and still a hot wheel. I'm thinking of buying a new bearing set and replacing as maybe it's the inner bearing making the noise? Bearings, rebuilt calipers, rubber brake lines all replaced last year and have about 12,000 miles on them. Any advice appreciated.
Thanks.
