4.10s and driveline vibes

[trailblazr81]

OK, first I wanna thank everyone here for helping me decide to go 4.10's instead of 3.73 or 3.90. But now Im hearing from "other forums" about a driveline vibration with 4.10's when coasting from about 80 down to 65. Does anyone else experience this? Cant be a good thing. I wanna leave the driveline vibration problems with my old lifted 4x4.

With 4.10s the driveshaft is always spinning faster so proper driveshaft balance becomes even more critical. It is highly suggested to do aluminum driveshaft when doing gears but not absolutely necessary. If you keep the stock shaft make sure to line up the marks when reinstalling.

I ran the stock driveshaft with 4.10's. I experienced some vibes over 90, and some while coasting downhill. It was never enough vibration to bother me, but slightly noticeable nonetheless. An aluminum driveshaft would have helped, but I never got around to it.
