Ian noticed that the '03 models list a 4.900 axle gear ratio in this thread.
Some of us are trying to find out what diff ratios were used on the 2002 models, when the 4.900 gears became available and what trim they were used on. If you have a 2002 Xterra, please post the following info:

Build date (top of driver's door jamb sticker)
Axle code (bottom of driver's door jamb sticker) such as HG46 or HG49

Vehicle trim:
XE V6 w/o sport package (no limited slip)
XE V6 w/ sport package (limited slip)
XE V6 w/ enthusiast package (limited slip)
XE V6 World Championship Edition (LSD?)
XE Supercharged (limited slip)
SE (limited slip)
SE Supercharged (limited slip)

Transmission:
Manual or automatic

I just got back from a dealer. They had an '03 XE V6 auto with just the power package (no LSD) that had the HG49 axle, as well as an '03 SE V6 auto non-SC (with LSD) that also had the HG49. So it seems the HG49 is not non-SC SE only as nissannews.com indicates.
I also saw 5 XE V6 02 models, all of which did NOT have the LSD and had the HG49 axle with both manual and auto transmission. The oldest was built in 12/01. I saw no '02 SEs and no '02 XE w/ LSD left on the lot.

Have a 2002 XE World Championship Edition, I'll look after work for the numbers. Question: how do I tell if I have the limited slip dif?

Look for an orange sticker on the back of the rear diff.

Looks like I'll have to add a new option to the gearing calculators...

OffRoadX,

Judging by the responses, I'm beginning to think the question should have been phrased slightly differently:

"Does anyone own a non-supercharged 2002-on V6 with anything other than an HG49?"

In our (un-scientific) poll, I don't see one...

It also shows that the HG49 has been around for 14 months now (Hunter's X and DesertHB).

Regards,
Richard

I may be wrong, but it seems to me that if you have an 02 with factory fog lights, then you do have LSD. Correct?

Yes.

Richard.

Right. My vehicle, an automatic, has no fogs - has the pigtails to hook them up though- and NO limited slip dif (as identified by orange sticker on the back of rear dif I'm told.) Built 9/01
