right side wheel bearing
have one person sit in the truck and one person with their ear on the gas tank. have the person in the truck turn the key 2 clicks and listen for humming. if there is no humming fuel pumps not working
With each wheel raised, Use both hands, one at 12 o clock position, another at 6 o clock position of the tire/wheel. Shake it, any movements? Should be none. Another way is, when driving, there is a "humming sound", it will get worse if you turn it to the right, or worse if you turn it to the left. The humming sound will go louder. If humming sound is stronger when turning wheel to left, RIGHT BEARING IS BAD. If humming sound is stronger when turning wheel to right LEFT BEARING IS BAD.
The most common thing would be worn tires. It could also be a bad hub bearing. When you turn the car to the right does the humming noise change or go away? If so, the left hub is probably bad. When you turn left if it changes the right hub is probably going out.
If its right after you turn off the key it might be a power antenna motor.
The turn signal flasher relay is under the dash of the 1996 Nissan truck. It is on the right side of the steering column.
Turn it off.
Turn it off...
stay behind it.
I have a similar issue with my Stratus, except instead of humming, mine rumbles slightly. This answer is only speculation, but I believe that it happens because the power steering is stretched to the max while turned completely to the right. You'll hear a humming noise because the hydraulics are trying to pump even more fluid in order to turn further, but there isn't enough fluid in the system. Alternatively, your passenger-side front bearing could be worn out, but it would be much more noticeable than just a humming noise.
I'm almost positive that the problem is a left or right wheel bearing. Replace BOTH. Easy and inexpensive.
Into the slide. If the back end is going right, turn the wheel right. If you turn out of the slide you'll end up doing circles.
The turn signal flasher on a 1977 Ford custom truck is behind the instrument panel. The instrument panel is located to the right of the steering wheel.
