hi Dale, Best practice is to drive the bearings in and out on the outter race in any normal installation. Applying impact to the inner race during removal or installation will normally reduce bearing life. Carrier bearings are big, and they are also limited use items, so if you don't have a drift to get to the outside race, GENTLY tap the inner if you have to. The damage will take YEARS to show up....Also on re-assembly, DO NOT use impact tools- tighten and tention by hand. Rattle guns will kill your bearings, even if you don't tighten it up fully- the jarring will briuse the hardening, and in a high speed application such as a wheel bearing or gearbox bearing, a failure will result...... a fact that my mechanics seem to forget at times, usually with the end result a new bearing needed 12 months later, all to save 2 minutes work.
