Perhaps worn tires (outer edges)
Tire pressure? I've been told that it is the result of imperfect geometry in the steering system, that one or both of the steering tires is not in a perfectly matched turning radius with the other. This results in part of the tread on one, or both, of the tires sliding [being pulled, or "scrubbing"] on the driving surface. That scrubbing, and the resulting sound your describe, is actually a mild form of the same squealing which occurs when "burning out," or when braking too hard.
I have a 1999 Chevy Suburban LT and if I stay at the recommended hwy speed I easily get 19mpg
It is located on the left rear of transfer case.
Most likely, 355.
Left rear of the transmission on 2 wheel drive trucks.
blower resistor is bad
Most common cause is your alignment. specifically the "toe" adjustment.
dig a very large whole and roll that p.o.s. into it and bury it. boom. done.
The speed sensor can be found on the side of the transmission and can be easily removed with a 9/16 ratchet. Remove the wiring harness from the speed sensor before removing the speed sensor from the transmission.
This car (the four-wheel drive is optional) has four-speed, electronically controlled OD transmission.
With no speeds at all, check the fuse, then check the blower speed switch and it's electrical plug.
There is not a gear in the engine, they do have a speed limiter in the computer. Also some older automatic transmissions have a "governor" to adjust shift points.
When your tires squeal at a low speed it can mean a number of things. The tread on your tires may be almost gone or you may have low tire pressure.
