Front drive shaft / wheel bearing question (1 Viewer)

[Indiana80]

On my 2005 LX, I’ve been experiencing a wa wa wa noise from ~20MPH up to highway speed where the noise just kind of blends in with the highway noise. I’m fairly confident that it’s coming from driver side front wheel area. My IR gun indicates left front hub runs about 120 deg F and right front hub runs about 105 deg F. My wheel bearing kit came today, so I’ll be swapping out wheel bearings and races in the next week or 2 hoping that cures it. Interestingly, I took an hour long interstate drive tonight and when I got home I shot the IR temps of the front drive shafts at the barrel that mates up to the back of the knuckle. Passenger was 120 degrees F and driver side was 150 degrees F. Front driver side drive shaft is just over a year old with 15K miles on it- OEM replaced by previous owner at Lexus dealership. I’m hoping that high temp reading is from inner wheel bearing. Any thoughts on why the front drive shaft would be that hot right where it meets up to knuckle when the part is basically new? I’d hate to do front wheel bearings then have to go right back in and pull drive shafts. I should mention that I did grease my spindles about 6 mos ago when I checked and adjusted front wheel bearings- both front wheel bearings had been running loose- driver side was the worst.

Check and make sure your calipers are not sticking

Assuming both brake pads look good and caliper is free (land sharks comment):
Once swapping in the bearings I'd throw in a new flange gasket and cone washers and perhaps order a new flange and c-clips. Not super expensive and good to have on hand in case you see any damage.

Yep, I’ve got all those items to swap in. I don’t think I’ve got a caliper sticking- just IR gunned both front rotors after a 10 mile drive and both scanned about 135 degrees F. Seems like if I had a brake dragging, one rotor would be noticeably hotter.
