Need 1999 TJ MainShaft
My mainshaft is inaccurate and this caused a very strong vibrations when running.
now I need a new mainshaft and i allready have 3 from different years (all from np231 transfer-cases), each one have a minor change from the other and now one is exactly the same as i have.
can some one please tell me which years are the mainshaft is same as 1999 4.0L automatic?
what about the eliminator kit? do i ahve to buy a new driveshaft too? what are the differents between the eliminator kit and stock mainshafts?
Thank you . . .
