Not sure how much the TOD is tied into the main computer. As long as it mechanically bolts up you should be fine but you may get a bunch of CELs if all the sensors aren't happy.
Before you commit, check the TOD error codes, check tire pressure, check all electrical connectors under vehicle, check transfer case fluid level. Ya may want to go to a grassy or dirt area & do some donuts in reverse (really punching it). Whilst your at it, try exercising the ABS - prolly not associated but it never hurts to try.
