Description
QU10083 1998-2004 Dodge 4x2 NV4500HD Rear Housing fits Diesel and V10 Dodge Ram 2500 and Ram 3500 4x2 trucks from 1998-2004. These bare, new take-out housings are from brand new transmissions we disassembled for parts. Order QU10025 rear bushing and QU10023 Rear Output Seal separately. These housings do not have the hole for a speedometer so they will not work on 1994-1997 trucks. USA Made.

Applications
Tech Note 1: Clean Mating Surfaces
Since these are cases from brand new transmissions we parted out, there will be some RTV sealant you will need to clean off the mating surfaces.
Tech Note 2: Housing Specs
QU10083 Dodge NV4500HD 4x2 Tailshaft housing is approximately 11-7/8"” long. The casting number is 25945. The bolt pattern on the front is the universal NV4500 8 bolt main case to rear housing pattern.
Tech Note 3: Transmission Mounted Speedometer
1998 to 2004 Dodge Ram 4x2 models utilize the rear axle mounted ABS sensor for the speedometer signal. QU10083 is not machined to accept a speedometer sending unit. If you need a transmission mounted speedometer, see QU10024.
Tech Note 4: Sealants
Early production NV4500 Transmissions used an anaerobic sealant (QU90003) to seal between the main case and input bearing retainer, top cover, and rear housing. Mid-production units used anaerobic sealant just on the input retainer and RTV for everything else. Later production transmissions used black RTV Sealant (QU90006 or QU90005) for everything. Either type of sealant works fine (except the PTO covers ALWAYS should be sealed with RTV), but I prefer RTV for all components. Regardless of which sealant you use, make sure excess sealant does not block the lube access hole at the top of input retainer pilot that fits into the transmission case! Also, the threaded holes in the main case for the four retainer bolts and 12 PTO bolts are open ended, so you must use new bolts with factory applied threadlocker or apply Threadlocker (S24200) to your existing bolts to prevent oil seepage past the bolt threads. See my TM1003 NV4500 Shop Manual or VSG1003DVD NV4500 Overhaul Video for more information.
