Re: 10 bolt corporate or Dana 44?
Front axles, which the original post was referring to, do not have c-clips but rather are a full-floating design.
Concerning the strength differences between the front Dana 44 and GM 10-bolt, the only real difference in strength is the 28 spline axles in the 10 versus the 30 spline axles in the 44. However, if you plan on upgrading to ORD chromoly shafts it doesn't really matter as the 28 spline chromoly shafts are already stronger than the u-joints so there is no reason to convert to 30 splines in the 10-bolt. Also, Warn no longer makes the front 30-spline 10-bolt axles so they cost extra to have them custom made and the rare factory 30 spline front axles are extremely hard to find (trust me). For the carrier change, if you are planning on installing a locker or posi anyway it's a moot point (a good aftermarket locker or posi usually beefs up the assembly), but if you plan on staying with an open carrier you will have to pay the cost of buying another carrier for the 44.
Or, as I'm sure someone else will say, buy a front Dana 60 which would already have 4.10 gears and stronger axles. The chromoly axles and gear change will probably cost around $800-$900........
