Section 2 (Drive Axle): Description
The Corvette uses 2 rear axle carriers, a Dana Model 36 (7 7/8" ring gear) and a Dana Model 44 (8 1/2" ring gear). The Model 36 is used in vehicles with automatic transmissions and Model 44 is used in vehicles with manual transmissions.
The axle is a semi-floating type. Differential carrier housing encloses the differential case and hypoid gears. Internal components of carrier are of conventional design, incorporating hypoid gear set with a pinion supported on 2 preloaded, tapered roller bearing assemblies, and a two-pinion differential assembly supported on tapered roller bearings.
Pinion mounting distance adjustments are made through the use of shims, as are differential bearing preload and backlash adjustments. Differential side gears drive 2 splined yokes which are retained laterally by snap rings located on yoke splined end. Yokes are supported on caged needle bearings pressed into carrier. A lip seal, pressed in outboard of the bearings, prevents oil leakage and dirt entry.
