shudder on take offi

[timelessconstructionllc]

I've got a slight shudder upon takeoff. Nothing when sitting still. Nothing once above 5 or 10 MPH. Any ideas?

Probably a driveshaft u-joint getting tight. Might want to consider a single piece driveshaft if so.

Already running a one piece shaft.

Mine has started doing this also, was told I need to change out my differential fluid...

Front, rear or both?

And while we are on the subject 75-90 or 75-140? I tow anywhere from 5k -25k. And run without a trailer probably half the time.

I'll do both, undecided what i'm going to use, maybe synthetic. I was told the friction modifier was breaking down causing the shudder, I just don't know, my u-joints all appear in great shape but appearances can be deceiving.

You should use sythetic since that's what's in there now and it's what Dodge specs. You don't have clutches so you don't need friction modifier.
