What exactly IS my diff??

[MidnightSXT]

First off lets take into account my mag is an ex rental, so maybe it has fleet options not available on non fleet sales. I have the build sheet for my car. This is a 3.5L v6 rear drive.. Axle code says DMWP 2.87 axle ratio. Well after reading the 06 service manual it says there are 3 axles available. a 198 axle is available only in AWD, and in v-6 rear drive models, available in 3.07, 3.65 and 3.90 ratios. Ok no ratios here match mine. Next is the 210 axle available in ONLY v8 equipped models with a 2.82 ratio. OK this ratio is very close to mine but i dont have a v8. Last is a 215 model, which the service manual gives no description of, so lets assume its for the SRT models since its the biggest of the three. This is definately NOT my diff. So what i`m concluding from all this is my v-6 car is equipped with a v8 rear axle?

I think the 5-speed trans SXT and R/T both get the same 210 mm axle... while the 4-speed cars get a spread of different ones.

AWD are all 3.07, and all 5-speed trans.

SRT are 3.08, and 5-speed trans
