also just went outside spun one side and they spun the same way then noticed a sticker near the end of the axel, trac lock,

 

There are thousands of folks here on CF running D35s. I've been here for about a year now and catastrophic axle failure is rare, regardless of manufacture. There are far more threads debating which one is better than there are reports of actual failure. The C8.25 may hold a marginal advantage on paper but in practice (as far as I can tell) it seems there's no appreciable difference in reliability when compared to the D35.

 

The ring gear is 8.25 verses the D35 7.62.
The 8.25 pinion is the same diameter as the D60.
The 8.25 axle tubes are thicker and stronger than the D35

and size does mater when u look at the d35 compaired to the 8.25 it looks way beefer

 

give me a d35 with my current setup and no change in driving style, i will break a shaft every trip. Been there done that.

 

a 29 spline 8.25 is comparable to a D44, and c clips can be taken care of easily with a c clip eliminator kit. Compared to a chryco 8.25 the D35 is a turd.
