'91 4runner front end squeal - stumped
Running out of ideas on this one. '91 4Runner, 22re, ADD disconnected and front axle sleeve is locked in the closed position. I have a persistent squeal coming from the front end (right side, I think) that is tied to vehicle speed, not affected by brake actuation or the clutch. From 0-22mph it sounds like a gritty grumble, then at about 20-22 it's a rhythmic chirping squeal that gets louder, higher in pitch and faster as speed increases. Applying the brakes doesn't change the sound at all.
Sounded like a classic wheel bearing issue, but no dice. Checked inner and outer bearings on both front wheels, and the bearings are perfect, grease is clean. Races are good. Just replaced the left CV, right is about two years old; both boots are good, joints are packed with grease and clean. Plenty of meat on the brake pads; wear indicators are about 3mm away from the discs. No obvious leaks anywhere on the axle.
What am I missing?

I hadn't thought of the spindle bushing--that makes perfect sense.
Checked both wheels when I did the bearings, and everything turns very freely; no binding.
Thanks for the tips!
