Default Identifying axle gearing

Need help identifying the gears in my front axle

The ring says L4 D44-411T 304 and then 079 on the opposite side to the first numbers

Should be a small metal tag, held on by one of the diff cover bolts, that has some numbers on it.

So stock was 3.54. But, by the numbers on the gears, looks like 4.11's......

If you have the driveshaft off, (four bolts... really easy) mark the ring gear, note it's position, then see how many times the pinion gear goes around for one revolution of the ring gear.

HeyYou haha was wondering if you were going to be the one to help me solve another problem, the trucks been great since we solved the misfire issue but getting it into 4 wheel drive isn't so great. When I lock it in and try and drive it feels like the front is working against the rear, which is why I pulled the cover and don't trust the tag, there's been a few weird things with this truck that the previous owner never told me about so trying to figure it out

If you have different ratios front and rear, yeah, it just ain't gonna work well. It'll break things if ran that way. Verify ratios on both ends, see what ya got.

4.11 without a doubt, you'll have more power, better fuel economy, and a longer lasting transmission as well...

Should be a decal on the underside of hood, next to the hook as you look up. It will give you a ton of info including axle gearings
