Mainly spinning 1 tire...

Maybe thats part of my issue not sure, i had a mopar trans and driveline guy set up the third member for me. Im running 275/60r15’s. I might have it do it once every 10 times i drive in that certain place. Not sure if its just a characteristic of the diff paired with the 4 speed or what, nothing is broken yet so i guess thats a good thing lol. Im with ya aj, i put one 8oz bottle in it to start and i put another 8oz bottle in it and seemed to help a bunch
