{{Copyright}} ++introduction== There have been several very good Mopar rear axles used through the years. This page will help ID them ==ID by shape== The easiest way to identify an axle is to look at the cover on the carrier housing: *7-1/4" has a 9 bolt rear cover. *8-1/4" has 10 bolts, evenly spaced. The cover is almost perfectly round. *8-3/4" has no rear cover. The back of the axle housing is round. The center section is removable from the front of the housing. *9-1/4" has a 12 bolt rear cover. Rear cover is roughly octagonal (stop sign-shaped). *9-3/4" has a 10 bolt rear cover. The cover is wider on the driver side. ==Casting numbers== These may not be all the casting numbers that were ever used on the various axles, but are a starting point: ;7-1/4 :2070051 :3507881 :3723675 ;8-1/4 :2852905 :3723598 :3723599 ;8-3/4 :1820657 (small pinion shaft, up to 1964) :2070741 (small pinion shaft, 1965 to about 1972) :2070742 (large pinion shaft, 1957 to 1968) :2881489 (tapered pinion shaft, 1969 to about 1974) ;9-1/4 :3507890 :3507891 :3723199 ==Resources== [[Image:mopar axle.jpg]] [[Category:Rearend]] [[Category:Identification and decoding]]
