    I can post a picture when I get home but when I replaced the front diff I searched the part number on it and got one from a pick n pull but it said 4.10 gear ratio on it and I’ve been in 4wd plenty of times since I replaced it no hopping or front end spinning faster or slower than the rear so I figured it’s 4.10 in the rear too

    Take a look at your door jamb sticker and dollars to donuts it will say A04A as your axle code. What's been said about you not having 4.10 from the factory is correct. As far as which gears you should run for 37s, 5.29 will be the better choice with your auto transmission.

    You could be right just wonder why it already had a 4.10 in the front because when I searched part number on diff that’s what showed but if it does only have a 4.10 in the front I feel bad for it when it was in 4wd all those times

    It's probably worth figuring out before you grenade your transfer case. Or, use it as an excuse to swap gears asap so you'll know they're the same.

    Someone else correct me if I'm wrong, but here's how I think you do it, though I've never actually done it. Might be worth double checking what I'm saying with a YouTube video.

    Let's say you have 3.73:1 gears, that means for one full tire rotation, your pinion will rotate 3.73 times. Put your axle on jack stands and then disconnect the rear driveshaft. Take a paint pen or something and make a mark at the top of your tire and the top of your pinion. Slowly rotate the tire, counting how many times the pinion rotates. After one full tire rotation, your pinion should have rotated 3.73 times.



    This is your pinion.

    Correct, 1 full tire rotation should turn the pinion/driveshaft 3 3/4 with 3.73 gearing

    Why even disconnect the drive shaft?

    Definitely time to regear appreciate the info it came out to 3.73 I thought it was 4.10 all along it pushed these 37’s pretty decent other than up hill won’t be putting it in 4wd until I get that done I think I’ll go with 4.88’s what brand gears do yall recommend?
