Thank you all for the advise. I guess it would be a great way to work out fast but also to spend more money than what I would be saving. Thanks again. As for trading up that will take some time ...

Thank you

 

Locked diffs will prematurely wear out front end items... bearings, joints, gears etc.... not worth it... too much strain on the front...

 

I just picked up my 2006 500 4x4 auto last week out of the crate. I have already put 30 miles on it and most of that was in 4 low and beleive me, I have had to use the locking front end several times. It is cool to be able to lock and unlock the front at will. The back is locked solid at all times. We still have a little snow left in the foot hills here and locking in the front diff can either make or break your forward motion. You had better be aimed in the direction you want to be headed before you flip the lock lever or you may not attain it after! Have fun and keep the rubber side down..
