well i got in trouble again hahaha
this shouldnt get deleted i hope im trying to help out this guy and others on the road
all im saying is that its unsafe, using a dana 30 front with 40's on the road is scary. Heres the differences:
1. Braking power wouldnt be sufficient. Dana 30 brakes are small 40s are heavy and alot of rotating mass at highway speeds.
2. The dana 30 unitbearings have the tendency to break under stress like big tires.. i know ive seen it.
3. getting the gear ratio for ease of driving would be difficult i would say (dana 30 tops out at 4.88)
4. Steering issues. You would need hydro assist most likely and heavy wall/ heimed or BIG tre's. If you say no you dont ask yourself... What happens if i hit a big pot hole going 60mph and the stock tierod ends snap tossing my truck into a passenger car.(stock dana 30 TREs are small ment for tires around 31 ish)
5. Ball joints on the 30 would be under alot of stress breaking those going 50mph wouldnt be good.
6. fast wear on all mechanical parts.
7. Expensive to set up mechanical hubs, the front end would always be engaged if running a non vac disconnect.
8. the height of the truck and tire size would most likely result in big bump steer, again not good for other traffic.
please just be smart about it . I am not being a dick and im sure everyone will say your wrong blah blah blah at least i can say i tried to help
