Driveline issue

[mag]

I had a trac loc with 3:73s installed along with a Dynotech driveshaft I am now experiencing a speed sensitive rumble . The noise is more pronounced on acceleration any input would be appreciated.

Sounds like you should go have the gears install checked.

Did you get new u joints with the driveshaft? If so, I would have to think it has to do with the gears. Hope you find the problem soon.
