High pitched squeal similar to a bull elk's bugle with some mechanical grinding-ish noise thrown in.
91 FJ80 with lift and 32's.
I get a high pitched squeal under heavy load such as:
* Climbing mountains in Pennsylvania - steep enough incline that the road has truck run-off ramps
If I let off the accelrator the noise stops. Resume application of accelerator, and it almost always returns.
I had to stay under 35-40 MPH to ensure the noise did not return
* hard acceleration - like merging onto interstate (mostly only if it downshifts)
My 87 (almost bone stock) FJ60 makes the same noise if I stay in gear a bit too long while accelerating hard.
I don't drive these like race cars, but sometimes you gotta do what you gotta do accleration-wise.
Belts look OK and don't seem adversely loose (I have a problem with over-tightening things once I touch them).
Any help appreciated.
