My car exhibited viscous coupler rubbing. Xtreme was too kind and gave me great advice. Got to work and changed the diff and transfer case fluids myself. Turns better and brought down my anxiety about the unknown. New tools $30 Hypoid gear fluid $100. Extreme transmission saved me $100's at a local shop and maybe $1000's at a dealer. Thank you Extreme Transmission.
