gas mileage -- 3.54 vs 4.10 rear 2500 dodge 360 v8
From : ballyg
Q: 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 . cost involved for labor parts figure $500-$600 per axle for parts/labor remember that on a 4x4 you have to do both axles. you can also reasonably expect about 10% better fuel economy. so - pulling your trailer im guessing youre getting maybe 12mpg youd get an extra 1mpg out of the gears. figure youre paying $3 per gallon of gas so right now youre paying $0.25/mile. with the higher economy youd only be saving $0.02/mile. it would take you 50000 miles to pay for the new gears. .

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 . cost involved for labor parts thanks do not assume the 3.54s will get you better milage. when i went from 3.55 to 3.92 my unloaded intown type driving went up 2 mpg. my unloaded highway milage went down 2 mpg. towing a car trailer/medium sized car on it got about the same but the truck pulled it noticably easier with the 3.92s. denny .

made the mistake of going to a discount tire store to have the rear wheels balanced. i put front brakes on my truck last week. i get lifetime warranty brake pads so this should have been a free brake job. the last one to have the wheels off was discount tire when i bought tires. on the front wheels i found 7 stripped studs and 6 bad lug nuts. only 6 bad lug nuts you ask yep. the left one of them off. good thing its a 3/4 ton or i would have only had 3 good lug nuts holding the front wheels on. i took the hubs off and carried them in to napa to have the studs changed out and the rotors turned. the rotors were worn almost to the minimum thickness. i decided while it was apart id replace the hub that i split open 30000 miles ago. my free brake job turned into 7 new studs 7 new lug nuts 2 new rotors 1 new hub and 2 hours of shop labor. im afraid to look at the back wheels. discount tire sucks. -- ken .
