Does anyone know what the rear axle in a 71 commando would be and what it would take to put it in an 85 cj I want to say I read somewhere it was a dana 44 and would drop right in but that would be to easy right

Dana44 info

Pay attention to centre section offset, spring perch location, brakes and track widths etc.

It's a one piece flanged Dana 44, 30 spline. Tread width is 50.0". Your '85 CJ's tread width is 55.1".

Tim thanks for, info one more question though when I measure backing plate to backing plate on my cj its 49.5 inches not 55.1 does this mean that I have narrow track not wide track axles? Also what about spring perch locations I thought that I read it was a direct swap? Thanks

if you have an 85 then it should be wide track.. havent heard of many people swapping narrow for wide.. but you never know.. i dont have the measurements here on me.. so i cant tell you for sure. my little green book is somewhere's but here. but i do believe that the cammando is narrower.. (is that a word)..but dont quote me..

I helped my brother put the axle from a '71 Commando (yes, it's a Dana 44)into his '78 CJ7. The spring perch location was exact, and it was one of the easiest axle conversions I have done. Measure the spring perches on your '85 and compare. It does seem like yours is a narrow track based on the brake backing plate measurements, though. If I remember right the '71 has smaller brakes, also. May or may not be an issue for you.
