    I can hear a squeaking when I am coasting at a low speed. It doesn't matter if I am accelerating or coasting. I think its coming from the back. Anyone know what could be causing this squeak and what I should look at first?

    None. Bone Stock. EXCEPT: Brushguard, tow hitch, both welded to the frame. It's good to have friends and a fully equipped garage!

    Check you e brake cable brackets. They're located by the rear sway bar links on each side of the frame rail. Put a little grease at any contact points to reduce the friction and that might alleviate the squeak.

    Tried the grease zerks, didn't fix the issue. I notice this squeak around 15-40 mph, as I increase speed the squeaks frequency goes up until I can no longer hear it. I'm beginning to think I might need a wheel bearing to be replaced, it sounds like its coming from the left rear side.

    Obviously I hope it isn't a wheel bearing because they cost $100 just for the part. Don't know if this is a job that I can do myself either.

    What else should I replace or grease? Could it be a worn bushing?

    Edit: and I'll try the brake cable bracket too.

    Could the rear brake shoes need replacement?
    Could the rear drums have been damaged, struck somehow, so one is slightly out of round, and thus rubbing on the shoes in one spot as it goes 'round?
    Could the rear shoes need adjustment? Too tight or too loose?
    Could the rear brakes, or all of them, need to be bled? Could there be a leak inside the drum? Could the cables for the parking brake need lubrication, adjustment or whatever? Could the bell-cranks need lube or adjustment?

    Just tossing ideas out there?

    Keep us up to date!

    Have you put it up on stands, chock wheels, put in neutral and hand turned rear wheels? Listen and feel as you rotate wheels. Maybe help you narrow it down.. Are you missing a cat? Lol

    @Trekker Did you ever resolve this? I am having the same problem with a 2015 4Runner. Symptoms are exactly the same as yours: high-pitched squeaking at low speeds, gets more frequent as I increase speed then stops after 35'ish mph.

    @DudeDnB, @Trekker I also have a 2015 4Runner and experience this front screeching noise, at very slow speeds and only when braking. I had the dealer inspect it and they couldn't replicate the noise, they flushed the brake fluid, noise is still present. They said it is possible grease from overfilling the ball join SPC UCA could have drooped down.. but I may just go and buy some new bosche quiet drive and ceramic pads and call it a day.

    From some article in the interwebs "the squealing noise is caused by high-frequency vibration of the brake pads against the rotating disc. Vibration is the unavoidable result of friction generated by the pads as the caliper clamps them against the rotating disc. Mounting the brake pads more tightly in the caliper would only make the noise louder."

    I've heard of a torn CV axle boot can cause squeaking. I don't think thats happening on mine
