rear axle upgrade on TJ factory ordered Q

[copper_diablo]

What Dana axle is the upgrade when you order a TJ (this case a '00 Sahara) with the 30" tires and 15x8 Jeep emblem Aluminum wheels (ones commonly seen on a Grand Cherokee)? Does an auto tranny or manual make a difference? The Jeep in question is an auto. The local Jeep dealer didn't "have time for looking that up" and I've searched high and low to no avail. Thanks in advance!!

When I ordered my 02 Sahara I got the "Heavy Duty" rear axle upgrade for like $275, the upgrade was a D44 w/TracLok limited slip. An easy way to tell is to look at the fill plug, if it's a screw in type it's a D44, if it's a plastic or rubber push in it's a D35, not all Sahara's came with the D44. For me I had no idea what it was, just heavy duty, yeah that's for me and probably the best $275 mod (except for the Rock-It-Man bumpers).
