I believe that even a 2 mpg gain on a standard US TOD would be worth the cost. I am still curious if there are down sides besides lack of AWD get up and go. I don't think the back lash would be an issue since there is no forward or back up pressure on the freewheelin front parts. --at least thats how my head sorts out what I have read so far..

The only time I see more then standard power applied to the front tires on the display on the dash is when I FLOOR the throttle.. and I rarely do that any more.. There is enough OOMPH in the regular driving to avoid situations I get Myself into on the road..

OffRoading I would think that you would engage the hubs even when you thought about going that direction since the system is designed to run that way anyways.

I really wasnt looking to install a new TOD 2HI/4HI/4LO. Just add the hubs

Thank you for the replys so far.. we have been keeping on track fairly well..

Thanks GM for your input.. (I never really thought about the JDM side of this issue and your insight has benefited this thread immensley.

So far I have learned that the hubs will help out if I lost CV.. and that there is a cost for isolating the fronts out of the system.. Albeit good or bad..

I reread this thread often as I can to see if I missed anything..

Thank you again (so far) for the time you take to enlighten Me.

Peace
Jeff
