The Novak Dana 20 front output rear bearing caps were designed as an upgrade to eliminate any gear oil leaking from this location. The factory bearing/shim cover is one of the few notorious locations a leak can be found on the Dana 20 case. This is due to the shims being placed between the case & the cap, with only a copper spray-gasket applied to the shims to seal the cover. The Novak shim/bearing cover utilizes a three tier O-ring setup to seal the case from leaking; two O-rings per bolt, one inside & one outside the cover, as well as one larger O-ring following the hole path inside the cap. This triple O-ring design is sure to eliminate your likely present oil leak at the bearing/shim cover. Installation of these kits is quite simple, especially with the help of the included detailed instructions.
