JEEP DANA 300 - INDEX RETAINER KIT
SPECIAL INSTRUCTIONS:
This kit is designed to fit the 1996 and up Dodge NV4500s. This retainer kit
will allow you to retain the later model tailhousing.
A special front bearing retainer must be installed on the front of your Dana 300, replacing the stock retainer. When
removing the six Allen head bolts, there are two pry groves located on the stock retainer. Use two pry bars into these
slots to remove this aluminum retainer. When the retainer is removed, you will find the drive gear, input shaft, and bearing
on this retainer assembly. By removing the snap ring on this assembly, these items will need to be taken apart. Once
the items are disassembled, you will need to set aside the stock aluminum retainer and the stock roller bearing. A new
sealed roller bearing has been provided because the new aluminum retainer does not have a provision for a seal. Using
these new components, reinstall the Dana 300 input shaft assembly using the stock snap rings. Once assembly is
assembled, you will then need to reinstall this retainer assembly back into your Dana 300 transfer case.
**CAUTION: Make sure the pocket needle bearing inside the transfer case is still in place and care should be taken when
installing so that the gears mesh. DO NOT FORCE . Use a sealant on the aluminum retainer between it and the case to
prevent leakage. Install the six Allen bolts to the transfer case.
The stock seal in the adapter housing may or may not need to be removed. This is depending on the chamfer on your
Dana 300. If this seal has to be removed, the sealed bearing is adequate in isolating the two gear box fluids. However,
some gear boxes develop pressure which will sometimes cause leakage between the two gear boxes. An alternative is
to run NV4500 fluid in both gear boxes.
