Puzzler for All You Viper Experts....

I used to have a 4x4 that made that sound every time the crank bearings went bad. Sooner or later it turned into a clanking sound and that's when I knew the bearing had desintegratated. Hopefully that is not it.

Have a Viper Tech you trust take a stethescope to it and see what his best guess is.

What's the engine RPM at the time? If it has someting to do with the rear main bearing or front bearing of the transmission, then it would be worse in 6th?

Ulysses: ..."every" time the bearings went bad? Ouch!

Sounds like an exhaust leak to me

Have the flex pipes (webbing) in the exhaust checked. If the webbing holes are opening up when they get hot it may be allowing exhaust noise and gases to escape. The area of the noise sounds right for this problem. How many miles are on the car and what modes are on it?

Yeah...sounds bad, but it was an off-road thrasher that had huge tires and 250,000 miles underneath her. In the span of the 250,000 miles I had her, the bearings went out 3 times. Not bad given the abuse she took (a lot of vertical runs).

I've posted this question before, but does anyone sell just the flex pipe section?

Even though the differential does not seem to be the source I would check it anyway. I just burnt mine up flying back to Texas in a rush. Too busy to stop and burnt a bearing which in turn whacked the rearend. Probably won't have the wheelbearing problem affecting your differential but that's another area I would check.

Noises can be seeming to come from one area when in reality they are comming from some place totally different. It may resonate depending on which gear your in more than other gears. By the time you figure out where its comming from you have much larger repair bill to contend with.

I would check wheelbearings and differential.
