Need to buy new ring and pinion gear

[joshnjulie1]

as already said if you do not have the 4.11 thick gears in the front then you will need a new carrier. if you need one i may have the old carrier with the 3.54 already in there all you need to do is swap them in. but i need to check the old garage to see if it is in there. just pm me to remind me.

I now set of 3.54's for the front. I can just use the carrier that the 4.11's were in right? Axle's link up to the spider gears like they should and the thickness of the ring gears are the same.

Not unless the carrier was a series 3 carrier that someone put thick gears on. Doesn't look like it.

From the factory 4.11:1 would have been on a series 4 carrier. To run the 3.54:1 you need a series 3 carrier.

I've always been told the 4.11's from the facory were thick and on a series 3 carrier.....So I'm incorrect in thinking this yes?

This is true for the Heep's, starting in 03' with the Rubicon. Maybe that's where the info was coming from.

How do I tell for sure which one i have and if these 3.54 gears can be put on the carrier I have???????

 

[joshnjulie1]

When I put the 3.54 gear and the 4.11 gear on the table, they were the same thickness. Am I missing something else.

There you go, your 4.11's are a standard set using a 4 series carrier. The 3.54's need a different carrier, a 3 series. The pinion gear is larger on the 3.54's set. If you tried to use the 4.11 carrier, you wouldn't be able to get the ring gear far enough away from the pinion, it wouldn't even go in.

Could be.......Thanks for clearing that up for me....

In my previous post, I have pictures that show the teeth of the ring gear chewed off. Would that necessarily mean the carrier is bad relating to the spider gears?

My thought is, the original Dana 30 is a 3.50. The newer one I picked up 4.11. Could I take the carrier out of the 3.50 front and put my newer 3.54 gears on it and place it into what was the 4.11 front?

The diameter of the pinion gear? 4.11 has a smaller pinion. This is where a "thick" ring gear comes into play. The extra thickness pushes the teeth over to match the smaller pinion gear. The different carrier moves the ring gear mounting surface over so it doesn't need filler metal of a thick ring gear.

You would need to take the carrier apart and inspect the spiders before knowing if they're good or not. If they didn't get chewed up when the ring let go, you should be able to use them.

Let's hope so. This "deal" I got is taking a turn for the worse on me if my old carrier is no good. Appreciate all the help.

If they are bad, keep an eye on the "for sale" section. Most guys go from the 3.54's to lower and thus buy a new series 4 carrier.....I see used series 3 carries and gears in that section often.

Will do.

For shits and gigles, when I have both carriers side by side (one for the 3.50 gear and the other for the 4.11 gear) what will be the defining factor on the difference? I want to be able to look at these and understand the difference.

You're talking series 3 vs 4 right?

The best way I can discribe it is with the carries sitting side by side ring gear mounting surface facing up, the series 4 will have the ring gear surface higher than the series 3. The carriers will be the same size overall but the case is proportioned differently.

Found this explanation:
If you set a 3 series carrier on your work bench with the ring gear flange near the bottom and measure the height of the flange from the bench it will be a little less than 2 1/4". A 4 series will be closer to 2 1/2".

Hope this helps

I believe that sums it up. Thank you very much for the info.

Finally took the series 3 out of the other front end and set them next to each other. I'll be damned, now I see what everyone is talking about.
The ring gear surface on the series 3 ring gear surface does sit lower in essence making the ring gear mount away from the pinion gear hence allowing the larger 3.54 pinion gear to line up correctly with the ring gear. I can now see why the series 4 would not work. Thank you everyone for the help on this. I did however notice slight friction of the spider gears (this carrier came from the ring gear that had busted teeth). I will play it safe an search out a new series 3 carrier. I would hate to go through all of this trouble only to put a bad carrier in the front end...to be continued

Take it apart and post some pictures of the parts. Then we can help you make the right decision if they are good or not.
