Hi everyone. Here's my issue. I have an 08 Tacoma 2.7L open diff 4x4. There is a groaning noise which resembles that of very aggressive off road tires on pavement ...only , its not. This groan occurs going straight and turning left...but goes away when turning right. It increases linearly with speed. There is no vibration to be felt. I suspected it was a wheel bearing so I replaced both front and rear passenger side bearings...the noise was still there. I checked the drive shaft carrier bearing. Fairly snug and very little play. Finally, I changed the front diff fluid...it looked like liquid metal. The magnet was filled beyond capacity and the fluid was clearly ruined. So , I suspect this groaning noise is actually a diff noise. I've owned the truck for 20k miles. It has 90k on it currently. Is there anyone out there who has had a similar issue and/or knows anyone who is seasoned in helping to rebuild a differential for the right price? Thanks in advance for any help you can give.

East Coast Gear Supply is right down the road from you.
If that's a unit bearing setup, it could also be the driver's side bearing. In my experience, they make more noise when they're not loaded. So the noisy bearing on a left hand turn is actually on the left side.
Either way, ECGS can look it all over and figure out what's wrong.
