I don't know if someone thought of this befor. But wouldn't it be easier and cheaper to make the hub mounting bolts the weak/shear point for the front drive line?
All you would have to do is replace the hub mounting bolts with weaker ones. This easy mod would work for ALL suzuki SUVs since they all have either a auto or manual drive hub. Or drive flange 99+ TrackVits.
What I am thinking of doing is finding the weakest bolts I can to replace them with. When they fail I will inspect the front diff for any cracks (2000 Tracker

)!
If no cracks I will replace the bolts with the next up in strength. And go from there.
I would rather carry and replace a hand full of bolts than carry and replace a axle, cv's, axle housing, half shafts, or what ever else.
This is similer to warn hub fuses it just uses the bolts instead. And if your thinking it's hard to replace a broken hub bolt your in the wrong LIFESTYLE. A good cordless drill, some sharp bits, and a screw extractor is all you need if at all.
