Your club sounds like it sucks.As said by literally everyone else. Get the lsd. You’ll be glad you did the further you get into jeep ownership and modification.
One of my clubs requirmenrs is no D35. Lol I know it’s a different axle but Jeep failed at giving this new one the same name
Also, all new advantek 44’s (220mm) are 32 spline. Rubicon or not.
