That video is more of a sales pitch for their reman axles. I did find a good you tube from eric the car guy. Doesnt look to complicated if I can get the right size socket for axle nut, dont know if I have any that big in metric. Prob loaner where i get the axle. I was just looking for specifics to the Magnum ( 300 or charger should be same). Its a 2005 3.5. I did find that they check fluid with a special dipstick to read temp? Might just do the axle and take it to local trans guy to check level ( same guy that helped me with my 904). I also saw a suggestion to take to dealer for oil change service and ask them to check it.
