Bearing and setup kit for regearing or rebuilding a Chrysler 9.25 inch rear axle, so new gears go in on new bearings with fresh hardware.
ExCel XL-1042-1 from Richmond Gear is the ring and pinion installation kit for the Chrysler 9.25 inch rear axle, the 12-bolt-cover rear found under Dodge Ram 1500 trucks and similar Chrysler applications. It is not for the later ZF-built 9.25; confirm by the cover shape and axle tag before ordering.
It is the bearings and setup parts for a gear swap or a rebuild of a noisy rear in one box, so you are not chasing individual bearings and shims mid-job.
When a 9.25 starts whining under load, the cause is usually worn pinion bearings that have let preload go loose, which then eats the gear pattern. Replace the bearings when you replace gears, set pinion depth and preload first, then carrier backlash, and check the pattern before you put the cover on.
