Abstract
A vehicle transmission housing or four-wheel drive transfer case housing which is shorter than previous arrangements, with the output shaft extending beyond the end thereof. As such, the drive shaft slip yoke or the output fixed yoke is mounted on the extended end of the shaft exterior of the seal at the exit end of the housing or transfer case, rather than extending through the seal into the housing or transfer case. The advantages include generally weight, part and machining reduction; reduced seal wear and performance requirements and, hence, minimized oil leakage; elimination of the usual grinding/polishing operations on the yoke; and consequent cost reduction.
