4" lift ,31s w/ 4.10 what mpg`s?

Post by scarecrow » Tue Apr 24, 2012 12:54 am

ive been thinking about getting and building another awd astro i miss my old 95. for those of you running a 98-04 astro with 31" tires and 4.10 or 4.56 gears what kinda mpg`s are you seeing? right now i am thinking of getting a loaded 98-04 lift it 4 - 5 inches run 31 inch tires regear to 4.56 do a transfer case swap so i can have the option of 2wd and 4lo. and to answer your question why 4.56 before you ask.
1) i bought 4.56s for my 95 and never installed em so as long as they will work i will put em in.
2) i will use the van to tow my toys up the mountains so the gear of the 4.56 will be nice for that.
3) i dont drive fast
4) most of my driving is city

'03, 30.75" tires, 4:10's, between 15.5 and 16.5 mpg.

I'd imagine it will change drastically depending on what you are towing, especially on the way up the mountain.

I'm with Tom on this one...my 98 had 30" tires, and 4.11 gears and would get 15 all day. I did see almost 20 on trips. I think 4.56's are a little steep, but if you already have them (and YES the ones you bought for the 95 will fit up to 2005) use them. Worst case is you go to a set of 4.10's later and sell the 4.56's.

Just as a side note, the front rebuild kit may or may not work for you. Depends on what you have whether it is a complete kit with axle bearing and seals or a basic rebuild kit. The axle bearings and seals are different.
