not sure if it belongs here, but have a yj dana 35 with 307s and has some form of lunchbox in it, and have some 4.10 axles i am going to swap in, i know 35 is crap, but have other stuff to do. will the locker out of the 35 with 307s come out and go right in the one with 4.10s. any help would be appreciated. this will be my first attempt at this. thanks
 
According to the powertrax website, there is only one part number for a dana 35 lock right, so you should be okay.
One thing you may run into though. Some lower gears (4.10 +)will not allow the cross pin to be removed with the ring gear in place. Most higher gears (3.73 down) will. You may be able to remove the lock right without pulling the carrier and gears, but you might not be able to get it in the new setup without pulling the ring gear, at least. Just make sure you are swapping in a matching front axle to go along with the 4.10 rear gears,too.
 
There are (2) Lock rights for the D35. The 2310 is for non ABS carriers and the 2311 is for ABS carriers. To simplify that, 87-92 were non ABS years and 94 and greater were ABS years irregardles of whether it was equipped. 93 is the pivotal year. 93 is the year they switched to ABS in the middle of the production year. If your old axle and new axle are both pre-93 or both are post 93 then you are OK. If one is pre 93 and one is post 93 then you have a problem. If either one or both is a 93 then you might be in luck but you have to run the numbers first. Numbers being the BOM.

The ring gear problem is with D30's not D35's. You won't have to pull the carrier/ring gear on a D35.
 
I see from your profile that your YJ is a 93. You'll have to run the BOM of your existing axle to see which lockright it would have. If you don't know the year of your new axle then you can run the BOM on it too in order to figure out if the lockright out of your stock axle will work.
 
If your 93 has 605528 then it will have a 2311 Lock Right. If the BOM is NOT 605528 then it will have a 2310. What year is your new axle?
 
I don't know jack about what fits what from what but you can grind the suface of a ring gear tooth carefully and then surface it slightly with a roloc disc if room is needed to remove or access the center pin. Just be sure to clean things up extremly well when your done and don't over do the depth of cut.. work slow.. and keep the parts cool by taking your time. This is a comon practice in very large gear sets and does not hurt its strength since the load is much deeper on the gear where the wear pattern shows up.:popcorn:
 
Don't try it on a D30 though. You have to take too much off to clear the cross pin. It's pretty small. I tried it once on a 3.73 set. Only took off enough to clear the crosspin and it was still nearly half a tooth plus some off of another.

Is the D30 pretty rare? I must be remembering doing that on a larger gear for a D35 and few other axles. Is it because the overall carrier and ring gear is smaller and makes the cross pin that much larger in the limited material?
 
It's not required on a D35. The cross pin will clear on all ratios.

The D30 requires grinding but on the 3.73 I did it was way too much. It was a trashed axle and I decided to see how it would come out. The 3.73 uses the low gear carrier so that is probably why it didn't work. Something I didn't consider before I posted. It might actually work on the high gear carrier (3.55 and up) and because there are less teeth it could mean that less grinding is required. So it may actually work. That's something I'll leave up to the people that have done it. I've only tried it on 3.73's and it doesn't work for them.
