I sort of disengaged from Cruiser world for about 7-8 years, but kept my 40. Now rebuilding a transfer case, and the last time I built a transfer case (in 2004) the thing to do was machine the speedo gear housing for a second seal. Have folks decided if that is still worthwhile or does a leak free 3sp transfer case really just hinge on a groove-free parking brake drum and a properly preloaded output shaft?
