Negatives to a spool

[Roxtar]

I'm rebuilding my 8.8 with alloys and 5.13 gears.
It's already heavily trussed and I'm running 35" Creepy Crawlers.
I'm considering going from a Detroit to a spool.
It's a trail rig, DD limited to big snow days when the G-Force tires on the Mark VIII are worthless.
Any reasons to change my mind?

[sawhead]

with spools in the snow how do you plan on turning very well,wouldn't that be a little trickier???

other than the obvious possibility of snapping an axle....monster amounts of traction

i know these obvious,but the only ones i can think of

[BRIANHO13]

As long as you have good shafts, they only negative I can think of would be tire wear on pavement.

I am spooling my 9".

[Haggar]

I know plenty in my club that run them. A friend is running a spool in his rear Dana 44, 2001 XJ on 38x12.5 Swamper SXs, and it does fine on the pavement.


It will defiantely fish tail you on snow, but so will a locker, and a locker has the unlocking effects in snow which can cause a spin out when one side unloads and doesn't have traction.

The Spool will always be predictable.


Heh, yeah, GeForces suck in the snow. My SRT-4 on 1/2" of snow was worthless...

[xj4life]

where are you getting the shafts from? Dutchman?

[XJ_ranger]

maybe this is good - maybe you can get some super beef 35 spline shafts or something...

hmmm :D

[Lawn Cher']

Now, keep in mind Brad that I am MMWMCC, but I think the simplicity, predictability and price of a spool makes it more desirable for a dedicated trail rig. I have them in both of my as of yet non-wheeled trail rigs. I did however like my No-Slip when my XJ was a DD.

To me this is simply a way to raise a little cash to help defray the cost of rebuilding both axles.

i was wondering why you would get rid of a perfectly good detroit for a spool

i would personally stick with the detroit.....but i like a decent turning radius

[David Taylor]

I went to a spool in the new axle from a Detroit. I can't tell the deference driving on the trail. Where I really notice it is shifting from drive to reverse. With deep gears my Detroit had about half a drive shaft slack before it hooked up. None of that with the spool.On the street is a whole different story. It's a trail only rig but I do move it around the parking lot at work. You should see the amount of rubber left on the concrete from my creepy's. But, I would still get a spool in the back again. I know it's not going to brake ever.

Are you going to clear enough cash between selling a used Detroit and buying a spool to make it worth it? Especially if you drive in snow occasionally? What else are you doing to the axle?

[Roxtar]

Are you going to clear enough cash between selling a used Detroit and buying a spool to make it worth it? Especially if you drive in snow occasionally? What else are you doing to the axle?I thought so based on finding spools for $100-$125 a year ago.
Actually, as I called around for pricing it became a moot point.
Not only have prices doubled but I just realized I can't run a spool with C-clip axles. :doh:

IOW


Nevermind.

[BRIANHO13]

find a 9"
leave your front fullwidth
put in a mini spool for $20.

[Roxtar]

Run the Detroit.

[seanR]

I am glad that the good citzens of NAXJA have helped you out with your delimma.
That is what we are here for!

Next question.....

[ROBZ95Xj]

.
not true, ipkyss is running a spool in his 8.8, i dont where he got his from but if ya shoot him a PM im sure he'd tell ya.

[BRIANHO13]

We are all forgeting about the lincoln spool.

[Jeffro600]

The Spool will always be predictable.

Ditto...as the springs/pins and other parts wear out inside of a locker, they start to be more and more unpredictable in their locking/unlocking characteristics. Not to mention, the different handling between when your on and off the gas. Less moving parts and a much less complicated theroy makes it more reliable and easier to do trail repairs if need-be.

The only real downside of a spool i can see is increaced tire wear...but then, i wouldnt recommend running one on a DD. My rear is spooled and while tire wear increace is noticable, its not enough to mandate a locker for me as my XJ will be lucky to see 5000 miles in a year(mostly to and from trail time)

[Rev Den]

You know....if you get into an accident and they investigate and find you have a spool, your insurance co. can refuse to pay and you can be held liable.

Just like no front swaybar.

:D

Got any references to back that up?? :rolleyes:

Are you kidding?

[OT]

If you want a real spool, you should weld it.
Never heard of anyone breaking an 8.8 carrier.

[Jeffro600]

Are you kidding?

No, id just like to know where hes getting his info from...i cant see why it would cause an insurance company to not follow up on a claim as its not really a safety issue as much as maybe say, a swaybar not being installed.

[Gil BullyKatz]

Any insurance will look for any way to weasel out of paying on a claim...

You think they enjoy paying up?

I can actually see them denying a claim based on the amount of "not for highway use-off road only" mods done to a vehicle...

hell they could probably deny it based on the amount of legal lift allowed in your state...

[OT]

just like how hard it is to break 8.8 shafts?

I still think his "broken 8.8 shaft" was a photochop.
Nobody can break an 8.8 shaft.
Period.

a 28 spline could be broken, but i agree the 31 spline 8.8 from an explorer with disc breaks that bolts into an XJ - no one can break thoes with the puny 4.0L...

id bet that the top fuel dragsters will start switching to 8.8's once they realise their potential...

i saw one break just a few weeks ago actually, V8 ZJ on 36s, the kid driving was a leadfoot on a near impossible 8' ledge and wouldnt give up, we were all amazed that it popped the shaft.

never say never gentlemen.

i think Sean is running a "mini spool" inside the diff.

I think you guys are on to something. I'd pay good dough for an unbreakable axle shaft package.

Hmmmm...

All you have to do is swap out your SuperNinjaUltraMayhem-60 for a junkyard 8.8 out of an Explorer and you'll have sweet disks and 4.10 gears and if you get lucky, you might find one with a limited slip.
Unfortunately, you'll have to relocate the spring perches which I'm sure is out of your league, so you'll have to farm it out.
But, at least it's not a c-clip D-35, ha ha ha ha.
Am I right, or what?

[ipkyss]

Hey mike, don't forget... I made it up that near impossible 8' icy ledge. Its just an XJ thing i guess... And my 8.8 is just welded up... Beat the crap out of it with 37s this summer with no breakage.

[sidriptide]

SPOBI!


um no.. Ipkyss is my witness.

[ROBZ95Xj]

are we talkin about the same ledge the big YJ rolled on?

[ipkyss]

Ya, the same ledge the blue yj on dana 60s rolled on. I did witness the 8.8 break. After all the beating i did on my 8.8, I couldn't believe it myself.

[Roxtar]

Actually this break strengthens my trust in the 8.8.
It hit hard enough to bend the ring gear teeth that were engaged when it caught traction before the shaft snapped.
I'm amazed the pinion gear and support held up to that.

[CRASH]

I'm amazed the pinion gear and support held up to that.


That's the strongest part of an 8.8.

Richard, I have an 8.8 that I'd be willing to trade for your Tera, if you float a little cash over to help make up the difference in value.

[Root Moose]

Kid, if you are really planning on doing a lot of winter driving on a spool, well, I wouldn't.

It's gonna want to swap ends every time you break traction in the rear end, kinda like driving a really tight LSD or locker in snow but it'll "always" be wanting to do it even when driving fairly gently.

I'm baised, I don't like TADs in snow on the street, would rather have an open diff compared to even an LSD for normal snow driving (as opposed to competitive, I'm watching my energy management and apexes for every metre I travel).

During the early morning fog of my mind during the morning commute I'd rather not have to drive the vehicle all the way to work. I do some of my best sleeping behind the wheel. :)

Warm up the CC/LoC and put in what you want, screw the half measures at this point. Six months from now you won't even miss the couple hundred extra dollars you are wavering on.

$0.02.

How about we swap and I throw in a Commanche with a bad motor.....that should work, shouldn't it?

Can you at least set it up with 5.13's to match my front? Oh wait, that can't be done. Damn!! :mad:

[Roxtar]

My 5.13s will be here Monday.

[XJ99]

hey I dont wanna run your post off subject but I figured I'd ask since the topic is spools and I dont really know what one is, Im pretty sure Its differerent from being lincoln locked (welding the spider gears)?....

I'm buying a rear d44 next weekend that has 5.38's and is "spooled".... It will be going under a dail driver and I'd rather replace the spool effect with a lunchbox or arb... something thats a bit less rough, maybe even a limited slip...

so my question is, what is a spool? Is It the actual carrier that acts as a locker? Is It as simple as having the spool removed and running without It? school me please.....

[Haggar]

In the future, you might want to school yourself *before* you buy parts that you don't know what they are..


A Spool is a full carrier. In most basic terms, its a 'solid' carrier. There are no spider gears. The axle shafts fit directly into splines into the carrier itself. There is zero differential action ever. Because its all one piece of metal, and usually quite beefy, they are very strong.

A Mini-Spool is like a lunchbox locker. Except its a single piece that acts as a solid coupler between the axles. Zero differential action. It uses a cross pin to affix the axleshafts to the OEM carrier, so the strength is dependant on the cross pin itself, and the carrier.

A Welded diff is when you weld the spider gears together and/or to the carrier. Strength is dependant on the quality of the welds, and the OEM carrier itself. Zero differential action.


All of these sometimes are referred to as a spool. All are not the best choice for a daily driver is tire wear is a concern.

[Roxtar]

How they act:
A spool, either full or mini, locked both tires together, forward or reverse, under power or not. When one wheel turns the other turns the same, period.
A locker, lunchbox or full, is exactly like a spool when under power in forward. When you hit the gas pedal, both wheels lock up.
It unlocks when coasting, however. This allows you to let off the gas in turns and have it unlock.

[CRASH]

Can you at least set it up with 5.13's to match my front? Oh wait, that can't be done. Damn!! :mad:


Oh Goat, you really ought to web-wheel more often. 5.13's are readily available from multiple sources.

I'll take the MJ though. I'll even throw in 4 sets of Dana 44 balljoints to get you through summer!

[cal]

My insurance broker called me a few weeks ago to inform me that starting 2006, my insurance company will no longer offer liability to vehicles with lift kits. The insurance company DID offer to let me keep my multi car discount if I kept just my pickup insured with them - I am switching both to AAA this month.

The insurance company who is dropping coverage is SafeCo.
