Looking for 4.10 ratio cuz i know thats whats in the front end cuz i checked that out and i have a dana 70 in the rear end and please help thank you

4wheelparts carries a big selection of ring and pinions. In my opinion you'll want to stick with 3.55 or 3.73 gears unless you are constantly towing 12k+. Much better fuel economy and still good for occasional towing. The rear diff should have an id tag on it that says what gears it has and if it has limited slip. Anyway mine does.

No. They both have to be the same or you'll destroy your transfer case.

If you are wanting to match your rear axle and you're not sure on the gearing, open up the diff. There should be a number stamped on the ring and the pinion. You take the number on the ring and divide it by the pinion. Example: Ring gear 41, pinion 11 comes out to 3.7272 which is 3.73 gears. If there isn't any numbers stamped, you can count the teeth on the ring and divide it by the number of teeth on the pinion.

Yeah Bryce is right, front end gearing and rearend gearing need to match. You shouldnt drive it in 4wheel drive at all till that is adressed. I run 4.10's in my truck with 33 inch tires and it will pull ANYTHING but best tank was 22 mpg. I miss having 35 inch tires cause with the gearing it was perfect, boosted milage to 25ish and still had the power. I recomend changing your front to match the rear UNLESS you have bigger tires or are gonna tow alot. Also I recomend 4wheelparts.com, customer service is good, price is average, but good selection usually.
