Tech Note 1: Prior to 1985
Prior to 1985, GM used QU50284 10 spline input shaft on NP205 transfer cases behind the SM465 4 speed manual transmission and QU50044 short 32 spline input for Turbo 400 applications.

Tech Note 2: Clutch Teeth
The most common wear issue with NP205 input shafts is worn clutch teeth. It does not take much wear on the input shaft and sliding clutch collar teeth for the transfer case to "jump" out of high range. If your input shaft has significant wear on the clutch teeth, replace it and the sliding collar.

Tech Note 3: Wear Locations
NP205 Input Shafts may also have damaging wear other locations. Input shaft with significant wear that can be felt with your fingernail should be replaced with a new shaft along with the matching component. Look for wear at these locations:
Rear Bearing Pilot: Indentations from the needle rollers that fit in the front of the rear output shaft
Helical Gear Teeth: If run short of oil, teeth will show temperature discoloration and/or visible wear
Input Splines: Visible wear on the splines is usually caused by lack of lubrication
