Tech Note 1: Ford NP205
Ford only offered the NP205 Transfer Case from 1973-1979 and all are left drop models with the front output shaft on the drivers side. From 1974-1979, Ford offered both the part-time NP205 and full-time NP203 transfer cases for F-Series 4x4s. Ford used a remote mount in the F250 from 1973 to 1977.5 and direct mount units from 1973-1979. For 1973-1977.5, only the 1/2 ton F100/F150 was available with the direct-mount NP205 (for 1973-74 with auto transmission only). The F250 got the direct mount NP205 when the 1977.5 "Low-Boy" truck debuted, but the Bronco had to wait until 1978 when it was up sized to the 1/2 ton truck drivetrain.

Tech Note 2: Used Inventory
Our QU50260U inventory are used components taken from NP205 assemblies we disassembled for parts. These Input Shafts are good and usable, but they are going to show evidence of use. You can return it for full parts credit/refund for up to 30 days for whatever reason. After 30 days, it is yours.

Tech Note 3: 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 4: Wear Locations
NP205 Input Shafts may also have damaging wear on 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
