Re: Dana 30 front tuff enough for my use?
With all due respect to those who say it will hold, I have to cast some doubt. I have a stock 258 with 30" tires and 3.54 gears. A couple of weeks ago I was stuck nose down and couldn't go forward. In spinning the wheels trying to back up I shucked 9 teeth off the ring gear. I have a T18 where reverse is in the 7:1 range, but there still isn't a lot of torque there, and all four tires were in soft dirt. (That's why I tried spinning them) It has less than 70K miles, has never been thrashed, and has had fresh lube in the gear cases several times since new in '78. I do plow some snow with it, but not a lot.
I am not going to bother putting out $300 or $400 to replace the R & P; I'm looking for a D44.
And in your case the pinion in a 4.10 set is getting pretty small. I wouldn't give it much of a chance to hold together, especially with a locker.
