I am a new member, and new to the Xterra in general. I picked up a used 2009 and I need to replace the rear axle. There are several good use around but I am confused as to the gear ratio. I cannot find a tag on the axle, and the door sticker ends just below the "Trim X "
the Model number is TLKZLRNN54EUA----E so I think that means is an "S" in spite of the trim being listed as X.

I really would appreciate help as I don't know if the axle ratio is 3.13 or 3.39 or other.

Thank you all for a very educational group!
