I admittedly don't know a ton about toyota axles except that I've always heard good things about them being cheap, reliable, durable, and plentiful. Same with the D44. If toyotas are what all your friends run and that's who you tend to wheel with, then it's an advantage to have the same gear since there tends to be more knowledge and spare parts nearby. As for the Indy 4x4 kit, I think it still needs to be installed by an offroad fab shop, so if it was me, I'd talk to a shop first, they may offer you a better deal or options if all the parts and work are done in house. Like ZEUS mentioned in another post on here, a front locker only tends to blow out CVs if you are stomping on the throttle and then only usually if you are turning the wheels(more stress) or having intermittent traction like on rocks when the wheel catches. In normal situations, I'm sure a front locker is just fine. However if you are trying to go with bigger wheels, you may need the solid axles strength. Just out of curiosity, when you are going up these dirt hills, do you pull up on your parking brake at all? The limited slip in the rear will usually engage at that point and basically lock up the rear so you aren't spinning back there. The VX's limited slip is pretty good so it's worth a shot in the mean time. Good luck!!
