Think this would be an issue with the Rams?
IMO
Well that's a loaded question............but, yes, it could be. However, I don't think I'd worry too much, just be cognisant when the front end is flexed out, especially when the wheels are turned.
Now to be fair, I did have a Loc-Rite up front in the Tacoma and let me tell ya, that thing was a BEAST for a full bodied, IFS rig, lockers front and rear will do that for ya!
Now for the ram, having an open diff will work in your favor and if you have the 44-44 on demand case, that would probably help abit as the shock load transfer should be a little less but that logic may go out the window if you are mashing the gas to "keep" the case locked up...........
And it's not like you can't snap a cv on a stock ram with the sway bar connected..................just be smart about it and hey, at the end of the day a cv isn't hard to replace. I kept a spare in the Tacoma and could swap one out in under 30 minutes on the trail (yes, I snapped a few and had a little practice, as did some of my fellow Taco wheelers)
