Opinions-New output shaft against old ring gear?

[turbovanman²]

I can get a brand new output shaft for $60, but the ring gear is $275-:eek:

Thoughts on using a new output shaft and good used ring gear? I know it could possibly be noisey also but I am willing to live with that.

[BadAssPerformance]

how bad does the ring gear look?

I have a few and they look good, or I can get another one from my parts guy.

Sounds like a $275 gamble... what will it cost if it breaks vs. this?

The only reason the teeth broke on the ring gear was the exploding output shaft teeth?

[BadAssPerformance]

I meant if the used ring gear causes an issue, you'll be out a $60 pinion plus the $275 for a new ring gear plus??? vs. spending the $275 now.

I'l only be out $60 plus time. So I might just go for it.

I thought you were going to have your new gears magnafluxed??

I was going to have my new/used set done but If I can get a brand new output shaft for $60, theres no need. The ring geer teeth are perfect except where they got chewed by the output shaft.

Get a used ring gear that YOU haven't used. Seriously. Shooting in the dark has to be better than one that was part of one of your grenades.

Hahhhahaa, I know, i have a few spares that are unused by me. I ordered the new shaft so we'll see, it won't be here until next week.

With all the parts you break DC should have special air delvery. I had a customer from the Fenton plant that broke a driveshaft on a Mopar Rv near Plains Ga. The garage said a week or two. The cust borrowed the phone and made a call. (before cell phones) The garage owner freaked out the next morning when a corporate jet made a low pass over the highway and then landed on the return. New driveshaft in 8 hours.:evil:
I know I have a lot of bs stories, but they are all true.:nod:

[turbovanman²]

Hahahahahaha, thats a good one. I wish I had connections, that way I could get my part sooner. Doesn't really matter, I don't have the time anyhow. BTW, someone told me there not a matched set so it doesn't matter. :thumb:

[DUGZSHELBY]

I think you would be OK but Id recommend checking the gear pattern "mesh" with some "dykem blue" just to make sure your getting full gear contact. A used gear meshing with a new one may not fully mesh correctly and lead to another failure.... which Im SURE you dont want again!

[MiniMopar]

When the sprag teeth go on a gear in a manual tranny, you have to buy a new gear. The other side of that gear pair is on the input shaft, which has all four gears cut right into the shaft. Therefore, if you had to make sure both mashing gears are new, you'd have to buy a new input shaft every time you had to replace a gear. Then you'd have to replace the other three gears, since the new shaft has all new gears.

Unless something strange was going on with the old gear that caused it to wear unevenly across the teeth, you should be fine. The new gear should have a slightly rough finish that should break-in quickly to the old gear. Dugz idea will make sure that you are OK. Giving it some highway miles before wailing on it is never a bad plan either.

[turbovanman²]

I just wasn't sure if they were a matched set, but apparently, there not so all bets are off.

Good idea Russ on doing some highway miles first, :thumb:

It doesn't matter. I've used new with old just to "experiment", And it worked fine, even funny that there was no noise *most* of the time! I think a matched set would be better, but I woulden't pay 275 for a ring gear. Get a used set outta a TBI car. 1991+ should be solid pinion.........

The new ones are now solid so that part is cool. I have a solid one in one of my parts trans but upon closer inspection, one tooth is chipped, grrrrrrrr. :mad: Then calling the dealer, my pleasant suprise to find how cheap a new one is. I guess my loss is your guys is gain, all this new info coming about or being resurfaced, :( lol!

I don't know if this will help at all but I am going to make a new diff cover, I will use 1/2 inch aluminum. It might help keep the deflection to a minimum or might not do squat but hey, it won't cost me that much to make.

[MiniMopar]

Another thing to check is the diff centering. I didn't like how close the OBX brought the ring gear to the case on my A555. Looking at the wear marks on the pinion gear, it was clear it needed to move. That's why I put one of the shims (about half the total shims used) behind the other bearing race (passenger side).

[turbovanman²]

Thats one thing I did check when I put it together. It was perfectly inline, :amen:
