Hi first off i've searched and cant find quite what my problem seems to be.
Just driving through town all of a sudden i heard a bumping sound, vibration kind of like driving over road turtles or driving with a flat tire but not nearly as bad. It happend to me three times so far and i went and drove over each road where it happend multiple times to make sure it wasnt just the road which it was not. it onl last a few seconds then goes away and you can drive minutes or hours before it comes back. I havent been able to get it to happen again trying everything from fast acceleration to slow to just plain driving fast to slow. Shifting at different points in each gear. Turning hard each direction then driving straight. Etc. Could it be part of the suspension or drivetrain, transmission or anything like that? Any help would be greatly appreciated. Thanks

Go search for threads on this and see if it sounds familiar. If so, you have worn out RTAB(s) which will require attention asap... or you will be paying a lot.
