As long as the CV boots aren't torn, then I'd say go for it.
Some ... not all VXs with 3" lift will start tearing CV boots very soon after the lift. If PO did the lift some time ago & there are no problems then I'd say you won't experience any in the future either.
Unfortunately I wasn't one of the lucky ones. My CV boots tore soon after purchase & I had to do the diff drop. No problems since.
