Strange axle sound. It just started making a weird noise in the drivers side front, a weird combination of scraping and squeak like rubber sound. I could only hear it with the windows down. It went away with moderate breaking so I thought maybe the pads. Then I noticed it went away with moderate acceleration. I put it in neutral while driving and coasting, no noise. Revved it whiles stopped no noise.

I got home and lifted both fronts, rotated slowly by hand, maybe noticed it? Lowered it and went for a drive and now it's gone. I was going to post a vid but it's gone for now.

I'm. It sure if it's the differential, the axle, or something else. It's not the pads. Why would moving the tire back and forth and letting the front spin in opposite directions in the air change this?

I bought the truck at 60k and was told by the dealer (not Lexus) that they changed the diff fluids and transfer case. If that was done, maybe I'm due now at 111k?

Any suggestions?

Snd what hat gear should I use? Mobil 1 or Lucas?

 

I doubt the noise is a result of it needing a fluid change, I would suspect something else like the wheel bearings or CV joints.
