Often the difference between a poor rebuild and a good one comes down to this question: Did you replace all the small parts or not? We stock the shims plus just about every other small part that is still available for the NP205. From Case Plugs to Thrust Washers we have the small parts your NP205 needs.
Nuts: All the Shaft Nuts on NP205 Transfer Cases are prevailing torque Lock Nuts. As a rule, these type of nuts loose a percentage of their locking ability every time they are reused. For maximum yoke retention always replace your shaft nuts when rebuilding your transfer case or performing yoke or seal service. NP205 yokes are an easy slip fit on the shaft splines so it is not uncommon to find a yoke has worn into the washer. If your flat washer or flange nut shows ANY evidence of wear from the yoke splines, REPLACE IT!
Thrust Washers: One of the most common parts to find worn out in an NP205 is the thin, Tanged Low Gear Thrust Washer. The original part was made from a soft material similar to engine main bearings. Quite often the bent over tang will be broken and/or the low gear rollers will have worn a groove in the face. Replacement Tanged Thrust Washers are stamped steel. The Clover-Leaf shaped High Gear Thrust Washer gets clamped between the front output bearing and front yoke so it rarely needs replacement unless the yoke was loose.
