Tundra Issue Options

[Tad]

Although my 2005 Tundra is running great, and I'm very happy with its reliability and performance, I am having a minor problem that I can't quite figure out (probably because I haven't actually worked on a vehicle since owning a '71 Maverick during the 1980s (IMG:style_emoticons/default/tongue.gif) ).

Each morning when I back out of the driveway and turn the wheel I can feel a slight vibration in the rear (I think???) of the truck. The same problem occurs sometimes when moving forward at slow speeds while turning the wheel. At first I thought it might be a brake caliber, but have had the brakes checked twice and the front brakes replaced once. My 4-wheel drive is working fine, and the tires are all new. My mechanic thinks that it may have something to do with the differential (rear?), and verified that the fluid levels are all fine.

Anyhow, has anyone experienced any similar type of issues?

Any help or information would be appreciated.

Thanks! (IMG:style_emoticons/default/liebe011.gif)
