Odd problem. My 99 4cyl 4runner started making a loud squeaky noise when I put it in reverse. The faster I backed-up - the faster and louder the chirp. All heads would turn to see where the noise was coming from.
We find out that it's coming from the transmission directly below the drivers seat. I squirt some white lithium grease in there and it didn't help. After a few days the noise goes away. The noise has not come back but now:
When driving and not having the foot on the gas - between 35 - 50 it began making a loud shake/hum noise almost like a caliper/rotor problem. It is getting worse. No noise in reverse so i assume it morphed into this. I can now hear it at almost any speed and with my foot on the gas. You really hear it coasting down a large hill.
Any ideas? I'm about to get it into the Toyota repair shop unless someone can point me at the possible problem or at least a head's-up so I know what I am talking about.
It's got 130,000 miles - routine oil-changes - new Bumbo rotors about 6 months ago. New tires and whatnot. Working great until the noise starting when backing up. I don't feel much loss in power. No noise backing up. No leaks anywhere and fluids are all at the correct levels.
ANY HELP WOULD BE GREAT!!!!!!
