Q: on feb 23 231=a0pm tom lawrence tlawren...@earthlink.net wrote im towing a lighter camper & was thinking about changing out a 4.10 to a 3.54 rear for better mpg what difference can i expect . =a0 cost= involved for labor parts figure $500-$600 per axle for parts/labor remember that on a 4x4 you hav= e to do both axles. =a0you can also reasonably expect about 10% better fuel= economy. =a0so - pulling your trailer im guessing youre getting maybe 12mpg =a0youd get an extra 1mpg out of the gears. figure youre paying $3 per gallon of gas so right now youre paying $0.25/mile. =a0with the higher economy youd only be saving $0.02/mile. = =a0it would take you 50000 miles to pay for the new gears. lol .. i was just setting up a spread sheet to do the calculations after i knew what the percentages are ... and you figured it out already. yeah seems like i will stick with what i have because i pull a camper 6-9 times a year with an average of around 2k mi/yr.. thanks ! .
