I'm trying to answer a question for my girlfriend.... I'm searching online for the wheel bolt pattern of both an '04 Exploder, and and '98 Nav/Expedon't. Does anyone know off the top of their heads what both those patterns are? I found a site that lists '90-up Explorer as 5x114.3, and '97-'00 Expedition as 5x135. WTF??? I know my '94 2wd Seirra is 5-on-5.5 lug pattern, but this site says it's 5x127. I'm lost. Can someone straighten me out?
