My MJ rear sounds like it is grinding rocks. I am still driving it, but don't dare go far.
Dana 35, 44 or modded 8.25 works for me, but want a quiet one.
And a track lock,suregrip, or whatever you choose to call it would be great, mine isn't.
I am not a rock hopper or a mud dauber, and not running huge tires, so not afraid of a 35. One has held up to a LT1 in my xj for the last 5 years for me, soooo...
Oh, and my research looks to me like '72 to '84 Dodge pu will be about 3" wider, if you have one of those, I could get interested, I have saddles, would need to figure the angle of the dangle and find a good welder.
Thanks!
