The Story Of A Cummins Suburban (Lots Of Pics)

[justcuz]

Hey Mosesburb, what is your rear pinion angle set at? Do you think you may have a rear u-joint bind? Its hard to tell from the pictures but it looks kind of steep to me. Just a guess.

Love the completed pictures and the photos of the trip.

You running 4.10's?
You just went from about a 29 or 30 inch tire to about 33's right? I bet your mileage will improve some.
A .73 5th gear would give you 3.00's from the 4.10. It seems like you should be in the ballpark now. Plus the increase of tire diameter should net you a tick lower numerically.
