The GM AAM axle tubes exhibit a smaller diameter at the spindle compared to the AAM Dodge axles—measuring 4" for GM and 3.5" for Dodge from the housing. In design variation, newer GM trucks are aligned with Dodge axles. Additionally, GM incorporates a vibration damper on the yoke, while Dodge positions it on the drive shaft.
GM began making 4x4 Chevrolet Kodiaks and GMC Topkicks that utilize a Dana 70 front axle for the 2005-2009 models. These Dana 70 axles had open knuckles and ball joints. The Dana 70 axle only came with 5.13:1, 4.88,5.31 [citation needed] gear ratios and had a GAWR of [citation needed] these axles were rated at 7-9klbs as seen on 5500 door ...
GM's Automatic Safety Transmission (AST) was a semi-automatic transmission released in 1937. The first mass-produced fully-automatic transmission developed for passenger automobile use was the GM Hydramatic introduced in 1940. [1] The Hydramatic was a big success, and had been installed in the majority of GM models by 1950.
Total face width is the actual dimension of a gear blank including the portion that exceeds the effective face width, or as in double helical gears where the total face width includes any distance or gap separating right hand and left hand helices. For a cylindrical gear, effective face width is the portion that contacts the mating teeth.
Starter ring gear attached to a flywheel. In cars with a manual transmission, the starter ring gear is fitted to the outer diameter of the flywheel.The ring gear is usually fixed to the flywheel through use of an interference fit, [2] which is achieved by heating the ring gear and so that thermal expansion allows it to be placed around the flywheel.
Some dealerships are willing to run a VIN and print out its RPOs (with their definitions) free of charge. The records are in GMs' electronic database since at least the 1990 models. RPO decoder (for newer vehicles). Beginning as early as 1967, [2] and to all their models since 1984, GM attached a Service Parts Identification (SPID) label. The ...
A variation of the Dana 60 known as a Dana 61 was made to accommodate gear ratios that allowed for better fuel mileage. This was done as a direct result of the 1973 oil crisis. A 3.07:1 gear ratio was common for these axles and unachievable in a regular Dana 60. To allow for the different gearing, the Dana 61 had a greater pinion offset.
This ring and pinion is significantly stronger with a better pinion to ring gear tooth contact patch and angle. It was typically used in the back of jeep JKs, Isuzus and Nissan pickups. This ring and pinion does share some components and can be adapted into an earlier Dana 44 but requires some work, different bearings and spacers.
