Grinding sound need help

[Doyt W. Echelberger]

Sounds like maybe a heat shield that got pushed up against a turning axle 
shaft. There is such a shield, shaped like a cup, and it keeps exhaust pipe 
heat away from the inner boot of the US passenger-side front axle shaft. 
Happened on my 86 4kq, and to find it I had to put the car on a lift and 
look straight up into that area from below, using a strong light. Fixed it 
by poking around with a long sturdy screw driver.

Another possibility is that a splash shield on one of the front brakes has 
rusted and is getting deformed enough to rub against a turning metal 
surface. Happened on all four corners of my 86. Had to take the shields 
off. But if you pulled the wheels to check the brake, I'd expect that you 
noticed the condition of the shields, so that probably isn't the most 
likely cause.
