Front axle length?

Uh-oh. Time to do my front axles/CV joints on my 2002 WJ, and NAPA's website is offering me a choice of axle lengths....

How do I determine the correct axle length? Is it a function of the front differential type? Or...????

Yes, it has to do with the internals of the D30 front axle. If it's got a factory LSD (Vari-lock) as the Quadratrac or Quadradrive systems do, the axles are different.
