24 Unlike the rear, the frontend does not use threaded adjusters. Instead, it uses shims placed on the outside of the carrier bearings similar to a GM 10- or 12-bolt axle. Therefore, the carrier has a press-fit in the housing. A case spreader is handy to relieve the tight fit, but two prybars above and below the axle centerline in this manner can be used to pull the carrier out. Be sure to mark the shims to match the original setup with the new gears.
