Who's running bigger axles?

[JeeperRob]

I posted on the general discussion and got a little advice. Seems to be bigger rigs under this section so forgive me for asking this ? again. Here is the deal. Recently got me a 86 GW and plan on putting in a GM 10 bolt front and GM 14 bolt rear axle. 10 bolt will be replace later on. I now need a right side drop t-case and from what I got in the other section was is, I need a D300 or a Dodge NP208 right. I have the 727 transmission and Im looking for t-case options that I wouldn't have to use an adapter $$$. So does the Dodge t-case bolt up with ease and is it strong enough for a 38 inch or a little bigger tire??
Brad W. says he has a Dodge 208 case but Im thinking I can find one here so I don't have to ship one. My deal is if I buy a D300 Im looking at probably $300 to $500 dollars around here and if Im going to spend that much I might as well buy an adapter and use the NP205 case I have sitting in my shop. Im trying to do this on a some what small budget so I can get the wifes Scrambler painted and SOA buy next spring!!!!!

I don't know how the tailshaft or rear flange on the AMC727 differs from the Dodge 727, but if they're the same, I'd angle for a 203. Should be the same side drop as the other dodge t-cases, tough as nails and dirt cheap! Usually about $100.

like I mentioned in the other forum, I think you're better off keeping the 208. Plenty of people in the 40" tire club keep the 208 without problems, they're one of the best chain-driven cases ever made. The cost of swapping to a D300 is much more than just getting a ford D44HP that will bolt up to your front and be drivers side drop. If you're looking for 38s and larger though, I'd be considering a D60/GM14bolt combo, since you're at the limits of a D44 front with about a 37" tire. A D60 now is going to be a much more worthwhile mod than trying to change your t-case. Just MHO.....

Rob brings up a good question, what t-case do you have in the wag already? Unless you have the 208 that came in a few special orders, gov orders and fleet orders, then you got the 228 and a vac front axle right? So the GM 10bolt would be worthwhile to get rid of the vacuum axle even though you'll go bigger later on, and I wouldn't trust the 228 with any tires bigger than 33"s (even though I ran 38s with 229...once :D ). So unless you got a 208 already I think you're on the right track.

Does anyone know if the tailshaft and rear flange of the Jeep 727 is the same as the Dodge 727?

[JeeperRob]

Like I said above, Im on a small budget right now and trying to make do with what I have right now. I have a good connection with a salvage yard so getting a Dodge t-case will come pretty cheap!!! Im in need of something to wheel in. The wife got me this for an early birthday pressent so I wouldn't use the Scrambler. She keeps saying how are you ever going to get it done when you take it out and brake it!Hmmm. Not to mention the sticker she put on the top of the windshield, cant drive a jeep that says( Silly Boy's Jeeps are for Girls.) My salvage yard connection parts with T-cases cheap but axles are a different story, but then again maybe I can get him to swap me!!!

[JeeperRob]

Going by what my buddy and his dad said, it is a 208!! Its still sitting over at his house because Im to lazy to go load it up and bring it home. I geuss I better get over there and make sure before I make any plans. All I know is that its a little rough and it does run. I just took a quick look at it. I remember seeing the tail gate and it said selec trac!!! Don't know if that matters or not. To be honest with you wagoneers are a whole new ball game to me. I know CJ's but Im a dumby with the FSJ's for now. I'll go load it up tomorrow and bring it home and crawl under it. Its not in a very safe place to get under it right now. It looked like it had a D44 front rear.

[robselina]

selec trac is the 208. it's a great case smile.gif WAY better than the 229......

[robselina]

oh, btw, you should have drivers side drop front and a center output rear, both D44s. Don't toss them when you upgrade since they're the 'cool' swap to YJ and TJ guys. post them on a little jeep forum, or sell them to somebody in your local club to ofset part of your upgrade....

The output and input spline counts and shaft size matched perfectly.
There was a slight difference in the adapters between the 208 and whatever the Tcase was from the 85GW, it looked like it could have been ground down to fit.

[JeeperRob]

Well it looks like you guys might have me going in the right direction now, so Thanks!!!! As for the D44's my plan was to keep them for my Scrambler or the jeepster.
The rear diff is centered on the wagon. I recall a few years ago when I had my 82, seeing one at the salvage yard with an offset rear. Am I crazy or did I see that????
Well thnx for the help. I'll take some pics as the progress moves forward.

[FSJ Thing]

LOL! You saw correctly, the QuadraTrac FSJs as well as the D18 FSJs had rear outputs offset to the passenger side and the axle was offset to match. Sorry about any confusion I caused, Grand Wags all had the 229 or 219 except for 86 when they came with the 228. Only a few special orders and government/fleet orders came with the 208 so I was thrown off. ;)

[Robber80]

could you check your local salavage yard for a dirverside d44 out of a Widetrack cherokee or J-truck?? i'd keep teh jeep np208 and try to get a driveside d44 for now. also i know on all the new jeeps like 2004 select track is a transfercase that includes 2wd, 4wd, 4full time, N , and Low4. the part time case like the np208 is called comandtrac or something. was the naming for transfercases changed as they got newer?

[Bob Barry]

The NP208 was called the Commandtrac; the NP228/229 was called the Selectrac; the BW1339 and NP219 were called the Quadratrac. The Commandtrac was the standard case for the GW up through about '85 or '86; after that, it was only available for fleet use.

The rears were all offset to the passenger side up through '79; a little bit for the D20-equipped trucks (never a D18 in an FSJ) and a lot for the BW1339-equipped trucks.

That 10-bolt will work fine for up to 35" tires; maybe a HD-44 or 10-bolt from a 3/4-ton truck would work up to 37" tires, if you're gentle.

as for hd-44 or 3/4 ton 1- bolt holding up better, than a standard 10 bolt, I don't think they would since it's still same axles and u-joints, which are the weak links....

[Robber80]

i just don't like 10bolts very much. 14bolts aren't bad to me. but i'd rather just stick with a d44 or something in the front.

[scotty]

here we go again ;) the 10 bolt is almost as misunderstood as the FSJ amc 20,and is a better axle than the 44...

for the record,there is no difference in 10 bolts in 1/2 vs 3/4 ton,other than the bigger rotor and lug pattern. tube thickness and such is the same. actually,i have never noticed any differecne in FSJ housings,either,other than widths. scout 44 housings are way over-rated and use skinny,thin wall tubes.

i put together a 4.56 geared 10 bolt with a free gearset,and a $100 ebay EZ locker after i got tired of searching for a cheap used carrier/4.10+ gearet for a 44.

i break u joints on occasion,but for the abuse i put it thru with 38" SXs and a wide ratio t18 my 10 bolt (and 44for that matter) hold up fairly well. i dont really want to add the weight of my d70 up front till i have too...

[Robber80]

scotty, i just pearsonly wouldn't run it because i like a driveside drop axle for some reason. i dont' know its just my preference. i'm not saying ones stronger or weeker. i just like driveside drop.

Scotty is saying that the tubes on 0.5 ton and 0.75 ton 10 bolts are the same.

[Bob Barry]

Ah, ok; he's talking about 10-bolts only...

[JeeperRob]

Well I know several guys running 10 bolts with 38's that hold up. We mostly do trail rides here and make trips down to Disney OK. a couple times a year for some rocks!!!
I brought the Wagon home today and was a little disapointed. Started it up and backed it off the trailer after figuring out the cluster flup at the solinoid. Had a sliht miss in the motor so I started checking things out, oil was clean but the coolant is white and foamy Hmmmmm. Then the heavens opened up and let the rain out with a vengance so I had to let it be.
Cant realy complain for a $100. I have another 360 and a 258 if needed. Hopefully its nothing to major. I wouldn't feel to bad if I had to change the head gaskets. That would be some good experience for my oldest son......

i was just responding to the mistaken notion that the 44 is stronger than a 10 bolt(comparing standard cut axles) cause everything is more or less exactly the same,except for the 10 bolt pinion,which is bigger smile.gif 10 bolt shafts,diffs and gears are also reaaaal easy to find,which is another big plus in my book.

at any rate,not to worry,i didnt take any kind of offense to your remark,its just that 10 bolt vs 44 and amc 20 vs 44,along with ford 9" vs 14 bolt are some of my favorite web debates :D

[JeeperRob]

I would much prefer a 60 or a 44 myself but Ive had the 10 bolt sitting in the shop for two years now and have no money into it, just some trading. So I might as well put it to use until it breaks.
I was at the local mud run this last weekend and their was a guy with with a YJ sitting on 14 bolt rear with disc and D60 front with driver side drop and beadlocks sitting on TSL 44's fairly new. He said he would sale both axles,coils,links tires and rims for $5500. They have 513 gears and both diffs are locked. He is wanting to swap in unimog axles.

[robselina]

you can build a lot of stuff for $5500 smile.gif I'm a cheapskate though.....
