1996 Toyota Tacoma

Hello I’m hearing some sort of noise from the back of my 1st gen Toyota taco I jack up the back and spin the tires the dif is dead quite sound comes and goes my friends call me crazy because it never makes the sound when someone is around like a scraping sound I went under it to. Shake stuff around to see what’s loose I found that my spare is a bit loose

 

Looked at the rear brakes?

 

Those are drums and are brand new

 

But you can't duplicate the noise now?

 

I originally thought it was the drums but I changed them and the noise is still the same but comes and goes seems minor to me because my truck runs great and drives down the road just fine

 

Im in process of replacing my Carrier bearing due to a scratchy metallic type noise that we found in the diff. My noise was constant at any speed. It drove fine though.

Not to be confused with the Center bearing on the driveshaft.

 

Wheel bearings might be about to call it quits.

 

Noise comes in goes doesn’t stay constant I go on the highway even everything is quiet might be a wheel bearing otw out I do have 226k

 

Yep, could be the wheel bearings too, that wasnt my problem though.

 

Mileage is about right for failure, and mine did the same in and out noise for a few weeks before they went for good. Good luck with the diagnosis. Maybe the backing plate for the rear brakes is bent and rubbing the drum when the truck weight is on it? Pull a wheel off and see if there is a shiny spot.

 

This is the truck

 

Check the dust covers on your wheels to make sure they are t scraping inside of rim
Tolerance is very small, if they get bent just a little they can sometimes rub.
