The problem with the C-clip arrangement, even if the axles never break, is that as the friction plates in the diff wear, axle play goes up. If you let the diff go long enough, you can get a quarter inch of endfloat.

Granted, that does make for a simple way to check the condition of the diff, but it's just not right.

The Thing To Do is to hack off the ends of the housing and put 9" style ends on, and use 9" axles. But this is flippin' super mega extreme overkill for anything rotary powered that doesn't involve 10.5 slicks and a load of nitrous at the launch.

And if you're going to go to that kind of extreme expense, I see Summit has "Grand National" full-floater rearend setups on sale for about $700 - you get a clean, bare 9" housing, full floater ends, the axles, the hubs (you can get 5x4.5 bolt pattern), and a pair of 12" rotors, but you should be able to get 11" units no problem. Just add a pumpkin and you're done.

Or you can do the Toyota thing for half the price and a shit-ton less weight.

You know, I found that Land Cruisers '96-up have full floating rearends, too...

Damn near got my finger stuck in an 8.8 tonight.. That's what I get for using it to check fluid level.. That would have been a fun one to explain to the extraction team.

1.) If a dana 30 is sufficient (coming from my Jeeping days, that is just so hard to see) then an 8.8 in stock form is way overkill, no need to go looking for c-clip eliminators.

2.) If by some stroke of luck you are breaking shafts, Superior Axle and Gear was making a 'Super 88' kit for a while. Came with some nice billet contraptions to hold the bearings. It did make the axle a bit wider, but it helped me clear a lot of things easier with the tires a hair futher out.

3.) Glad you got it figured out.

Yeah realistically the Dana 30 with its 7.2" ring gear and (what the hell 29 spline---what a fucked up typical gawddamn stupid 'merikun in the baddest way means of measuring something--idiotic---and yet everybody uses it--fuck it!) With its 29mm spline ends is way heftier than all the little Japcrap OEM rwd stuff in like RXs and Commodahs,

And it would SEEM!!!! that with billions upon billions of Volvos in the yards there would be endless supplies..
'ceptin Volvo started doing a "em-biggen-ed" versio with more or less Dana 35 sized pinions and Dana 42 7/8 sized ring gears at some unknown point in the early 80s so a lot of the axles have a BIG PROBLEM using the affordable Dana 30 gear sets...

Second: Dana 30 LSD are simply put never gonna be found in the junk yards, and if you find them they (all 3 I have ever stumbled across) are always blown up, and blown up bad. The crossshaft for their 4 pinion set up breaks, the asleep at the wheel either hippie sprout-head driver or/ broke ass urban hipster both i-podding and grooving to tunes drives it till there's only metal particles resembling coarse sane left inside...

That's a big problem if you want a real LSD...(course you can make it into a ESAB diff, or a Kempi diff or in Norte America a Miller or Hobart diff, that works fine)

Yeah so mainly Europe only ring and pinions if you get a Volvo 1040 or whatever the fawk they call it)

Dana 30 lives just fine under my 250 hp wagon, beating the crap out of it at drift days and such. Lincoln locker.

Toy for sure but theres options for cherokee axle its a 35 with disk and 5 on 4.5

TSSFAB.US No HYPE just parts!!!! And check us out on Facebook!!!

Just to clarify you mean Grand Cherokee because Cherokees all have drums and post 90'ish all have AAM Chryco axles anyways.

No doubt that they work fine under those sorts of conditions. I've just spent too much time playing with bigger truck axles. The Dana 30 in the front of a Jeep, with its offset pumpkin, tends to be a bit of a weak link stock. We also have an extra 1000lbs of vehicle and a transfer case upping the torque input 2.72x to 4x. All the while we put large tires on and tend to get in situations where the tire really isn't allowed to move.

That all ends normally with a broken short side shaft.

Never really thought about the c-clip effect on LSDs. Makes sense, but again in this sized axle I'm used to a switch that goes from open to locked with no in-between.

At least if you find dana and yota truck stuff that fits, finding an LSD should be a lot cheaper than the other jap stuff.

John, what makes the 7.2" volvo stuff so much better than the 7" mazda stuff? Is it the axle design itself and not so much a matter of the ring diameter?

Size of the half shafts
Wall thickness of axle tubes, bearing size, intent.

Funny you should ask. Top shelf Sellholm now sells modded volvo axles as a replacement for the unobtainable Atlas.

hmm intriguing

volvo stock is what? 5x4.25?

It was a Ford Germany made axle originally supplied in bigger engined V6 Capris and Transit vans.

Now they are very expensive to build or buy, but everything you could ever imagine is available---but it could be a $4000 axle when you're all done..

As Alperti Kunkanenen points out in recent years the Volvo Dana 1040 thing has begun to be more popular in UK, Sweden and Finland.
I think they're calling it "Titan"...

I had one here4 but said fuckit and gave it to Portland's rezident Saab perv Garth who is doing some historic legal rwd Fords.

Is it true that the Atlas is a copy of a Dana something-or-other?

I forgot where I'd seen that... some UK forum. You know what the say about "internet knowledge"...

Hi newbie! Just found this forum from a british car forum and well here in the US I am the odd duck building a Rally TR8. I for over 4 years now thought about different rear axles for my TR8. I ended up with a Ford 8.8 from a 1986 Ford Mustang SVO with disc brakes and the ebrake in the rear caliper. I looked into a Dana 44 and finding one in the right size and converting to disc brakes or using a Jeep wrangler rear axle was almost a done deal. I bought the 8.8 for a steal that was already set up for a 4x95.25 bolt pattern, suspension mounts and well just needs the 3.55 gear changed for 3.73 ot 4.10s.

More than enough for 320hp & 360ftlbs of torque!
