I have a buddy who knows a kid from a local jeep group in MASS selling a d44 for 250 and i'm thinking of buying it but i'm not familiar w/ axles and what not so considering its so cheap (he says its in "good" condition) is there anything you guys would say i should look out for before buying it, or is this more like i wont know till i install it and drive it if something is messed up? Thanks for any info.
