Here's one example of acceptable gear mesh patterns as shown in the Yukon Installation Kit instructions. The manual describes the installation process in detail, giving practical tips, and showing these and many other good and poor mesh pattern examples. The resulting pattern from the test should indicate if the pinion depth is correct. If the depth is off, the carrier and pinion must be removed, and pinion shims changed. The whole assembly is rebuilt, backlash set, and the gear mesh pattern checked again. The process is repeated as needed.
