Why does everyone recommend an 8.8 over a Dana 44? Calipers or no caliper when that shaft breaks it is coming out. The break caliper will break with it if you try to wheel. The Dana 44 breaks you can still wheel.

The axle shaft strength tested by Warn Ind:
F8.8= 6,500 (lb. ft.)
D44= 4,600-5,000 (lb. ft.)
D35C= 4,000-4,300 (lb. ft.)
-------------------------------
COT: Continuous output torque rating
MOT: Maximum output torque rating

(Numbers from January edition of Fourwheeler, page 60.)
Dana 35 rear axle COT: 870 MOT: 3480
Dana 44 rear axle COT: 1100 MOT: 4460
Ford 8.8 28spline COT: 1250 MOT: 4600
Ford 8.8 31spline COT: 1360 MOT: 5100
Dana60 semifloat COT: 1500 MOT: 5500]

I get that the 8.8 is stronger. But of you break a shaft your still screwed unless you add the c clip eliminator kit.

That's the reason. You will be less likely to break it in the first place. And if you are still scared of breaking the 8.8, get a c-clip eliminator/chromoly kit for like $500. It'd be like twice as strong as a D44. Well, that's a little exaggerated, but not much..

If you get one with disc brakes you can limp it home alot easier then most alternatives....
The rotor/caliper WILL hold the wheel in until you can limp to a repair spot, same method as what happens wit breaking an axle with eliminators, only difference is eliminators will save you some brake wear....

Regardless, you dont want to wheel with a broken axle, you will get metal crud in bearings (they never break clenly, and floping around creates carnage) and possibly get stuck in an even worse place, better to limp and repair then wheel and seize up your whole diff....

Also, the 8.8 tubes are 1/4'' thicker. I welded mine to the diff housing for even more strength.
