First, you have a D30, not a D35. Yes, you can sleeve, gusset and run Chrome moly, but that might still be marginal for 37s, esp after regearing which will use a smaller pinion gear IMO. Yes, you can upgrade to a D44 and even a built D44 while at it, and yes, the D44 off of your JK sport will fit, not from a TJ sport though

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
