Well my 8.8 is in and I have a slight problem... my driveshaft is to short (if it were maybe 1" longer, I could have driven home... lol). Instead of throwing another 200-250 into another driveshaft, I think it's time to chuck the 249 in favor for a 231 with a 32 spline SYE and a new driveshaft. I don't really want to buy a used case as who knows what quality the innards are in (unless I feel like rebuilding the thing). I was looking at a 231HD from JBConversions OR getting a junkyard 231, rebuilding it with a 4:1 and HD output shaft OR... I don't know... I had a few people comment that the 4:1 is a bit excesive for stock jeep brakes and they recommended the 231HD, I've had people argue the opposite.... I just wanted to throw it out and see what you guys think.

I run a 231 D in mine .. It is very strong case .. I dont do much rock crawling but I can tell you that it has pulled my rig and a fullsize blazer with 3 people in it up a steep muddy hill with no problems.. That is almost the exact circumstance that destroyed my 242. :roll: (I gotta start driving to the top and using my winch.. :lol: )

Anyway.. I dont know anything about the 4:1 but I can give you rave reviews on the 231D ..

Oh and how did your shaft end up to short? Mine was about an inch to long when I put in the 8.8... :?

Your probably going to want to get the HD 231 before the TERA 4:1....i have heard/read several times...that if you use the standard 231 and the 4:1 it puts too much stress on the Tcase and it will fail in the mid-long term.

Speak to JB conversions, they should be able to give you more history.

Anyone else confirm this?

I have friends with both horror stories about mating a Tera 4:1 to a stock 231, and those with NOTHING but praise too. Mind you, the guys that like them, are in much lighter rigs.

My concert with a 4:1 on your setup would be actually stopping it on the trail. 4:1 and automatics + our tiny brakes = lots of drift.

I say go 231 HD from JB if you're going 231.

But if you're set on 4:1, why not flip a d300? Several threads on here have argued it's cheaper and parts are more readily available.

TEAMFX3 has a 231 w/SYE 8.8 and Clayton LA's -- using stock Exploder driveshaft

I think I'd look for a factory shaft that was a hair longer

but since you seem to like spend more money than just wheel it why not get an Atlas? I'm sure you can convince mom and dad to throw some dough at you for it :mrgreen:

i have the 231 fron a 97 TJ. and i wouldn't put anymore money into it. go for the flipped d300. wayy stronger. no slip yoke. and twin stick.

I've run 231's, with and without the 4:1 gears set, 249's, and now my Atlas.

The 231 is a great case, the 4:1 gears are great for control. However, if you're paying for everything at close to full price then why not just go to an atlas? You can have it built to order for you and be in it for 1600-1700 before you buy your driveline. I wager thats pretty close to what you would spend for a 4:1 231 or a flipped d300.

And you'll never have to worry about the atlas breaking :D

ohh, and BTW, I never had much of an issue stopping the 4:1 or my atlas. IT's a little stronger, but if you have a ZJ with the disks on all 4 corners, I don't think it'll be that bad.

Considering this is coming out of my pocket, I think 4:1 or an atlas are just out of reach. I'm pretty settled on the JB 231HD however I am going to try and see if they'll be able to get it to me by friday. Thanks for the advice.

I sell JB stuff....so this might be a little biased. lol

Flip a 300.

I will sell you a 300 flip kit, 32 spline outputs, twin sticks, and 4:1 gears for 1400 bucks or depending on shipping.

Every CJ on the face of the earth damn near has a d300....very comon. And the case is stronger than a Atlas.....

Would it really kill ya to just get a longer driveshaft? Mine was about an inch too long as well when I put the 8.8. Have you accounted for the flange adapter and everything already?

Nordic1
11-01-2004, 03:52 PM
yea... I put the flange and the driveshaft on after everything was botled up... the driveshaft sits perhpas 3/8" past the oil seal on the 249. I thought with the flange that the shaft would be long enough, looks like I was wrong.

Much to my disapoitment, I think I am going to get a new driveshaft and call that good for now. It looks like I'll be researching the 300 a bit and upgrading my t-case in the near future howeverI have to get my rig driveable before I can consider doing a T case swap. I have the 8.8 to break in. I need to build sway bar setups f/r. As well as front control arms to convert. I guess I'll prob bump this topic again a little closer to spring (besides I'll be up in the snow a whole bunch anyway this winter and the 249 comes n handy then).

Let me know. We can easily piece the 300 stuff together, so that come spring you are ready to put it in but it doesn't cost you 1400 all at once.

Would cost you a bit more in shipping but not a whole lot.

First thing you need to do it go find a D300. There were 3 forsale on pirate yesterday....lol. I bet you can get one for free if you know enough "Jeepers".

If it was me, I'd get a 231 from a junkyard and run it. Find something that's newer and it won't need a rebuild. I think I paid $400 for mine. Came from a 99XJ with 15k miles.
Rebuilding a 231 is cake too. The kit is like $150. You can have it done in a weekend easily.

As for the driveshaft, if you want to save some $$, just have if lengthened... cheaper than a new driveline.

231 is money down the toilet. Especially if you plan on continually building your Jeep.

231 is a good case don't get me wrong. But there are better options out there.

Sorry Brent but I went with the 231HD

http://www.transfercases.com/order.new.htm

These folks are out of OAKLAND!!!!!!!!!!!!!!!! Thats like 20 mins from my house!!!!!!!!!!!!!!!!! I guess these guys do alot of buisness with JB conversions (as in JB buys parts from TCE). I'll have the 231 in my posetion tomorrow!!! Schweet. Sorry I'm stoked because I thought my jeep would be imoble till I could order a t-case from JB (JB is at Sema and won't be back till next week).

Not a problem. But why did you spend 945 dollars (plus shipping I imagine, and TAX) on a Tcase that is aluminum, Chain Driven, not twin stickable?

Ease of installation?

Oh well hopefully my advice will help someone.

lol aside from the fact that it's a bolt in and yes chain driven (I drive a DD remember). IDK... I don't know anybody local with any experience with the d300 . Some day when I have the time, I'll do the 300 thing but for now I don't really have time to trim the tunnel and do the twin stick mods.

Cody

Damn, If I had known you were going to drop a 'g' on a t-case, I bet I could have sold you a 231 w/ 4:1 gears with 2 trips on it for that price.

yea I know but I didn't have the money for that sort of thing back when you were selling your 231

I'll see exactly what he wants out of it. I know he wants an atlas and told me to sell his, so I'll see what he's into it etc.

So is the 300 really the best way to go for a DD?

I am still not sure what TC I want to run in mine, I am actually thinking of an Atlas, but the 300 is something I want to find out more about.

Atlas or 300, you're looking at alot of work... both are VERY cool though
