You can replace the output shaft and tailshaft housing and other components that may have suffered the same faith without having to replace the whole t.case.

There should be a tag on the Backside of the transfer case that will tell you what it is.. I could be wrong, but it might be a 247..

thanks i will check ill upload pics on the fix ill be leaving for jersey on the 20 no work for me haha but thanks as always steelheadz

Look at the round tag attached to the rear half of the case, both the 207 and 231 were using in '87.

Your transfer case can be repaired in the jeep, but may be easier to remove it. It will need a new mainshaft, tailhousing, and tailhousing extension. I have all those parts if you're interested (if it's the 231).

If you were close to St. Louis I'd rebuild it for you, would take about an hour. Could also rebuild it if you wanted to ship it to me.

Any idea why it broke?

It's right at the bearing journal.

 

[87jeepwrangler]

it the pics is what broke the transfer case say the ratio is 272 so is that what it is

 

[Bounty__Hunter]

No, higher on the tag is the model number, either 207 or 231.

It's possible there are more problems inside. No noise or abuse led up to this breakage?

 

[87jeepwrangler]

no abuse led to this i think what happen was the cap on the u joint came out and then the drive shaft feel out. then the drive shaft when crazy and snapped the whole thing. i think and i will check the tag again tomorrow it too cold and dark out here sorry but i will update tomorrow around 12 thanks for your help

 

[87jeepwrangler]

Ok well i couldn't wait. The tag said 231amc so I'm guessing its a 231.

 

[Bounty__Hunter]

Yes. I have all the parts you need if you're up to the rebuild.

It's rather easy, get a set of lockring pliers (knurled duckbill ends) and use this for reference: http://www.pirate4x4.com/tech/billa...Jeep component service manual TCase_NP231.pdf

 

[87jeepwrangler]

how much are u looking to get for the parts

 

[87jeepwrangler]

and also what jeeps used that 231 transfer case what year and what model thanks joe

F.Y.I.. i just priced an Output shaft from a Dealer,$367.20.. your still going to need the tail shaft housing and other hard parts.. The New T.case (231) is $981.00 plus tax from a Dealer..I think you have a better deal with Bounty_Hunter.

 

[Bounty__Hunter]

Send me a PM or email at bountyhunter AT sija.org . I'll take care of you, will be a small fraction of dealer cost, even after shipping.

If your jeep has the 5spd, then your 231 has a 21spline short input. You want to look at other Wranglers with either the 4.2L and 5spd, or the 4cyl engine. The transfer case behind your 5spd switched from 21spline to 23spline so a 231 behind a 4.2L could go either way.

You can also get a 231 from a 4cyl XJ or MJ up to '95.
