That's the worst form of clip elimination, they are known to leak. There are other ways like 9" ends ect

I haven't had an issue and I go fast. I know plenty of people running 9's or more on stock. 31 spline 8.8's good luck breaking one. It's funny how against this rear end you are. There is a reason so many switch to it, c clips are cheep and easy to get away from if it bothers you, and its still a dirt cheep indestructible rear end.

Point me to a "specced out" 9" for $200 or less...I'll take 10.

It's funny how into ****ty rear ends TB is. Now I know you're kidding, the 8.8 is far from indestructible. I know why people switch to it, cheap isn't really a good reason when you've made a sideways move at best.

Nobody, including myself, ever said the 9" was cheaper, its just vastly superior. TB loves to delude itself that its little darling 8.8 is some magic bullet.

From one of the big block Ford/4x4 sites....

FORD REAR END WEIGHT COMPARISON

8.8-inch Rear End Assembly Weight : 170 lbs.

1. Housing: 36 lbs.

2. Axles: Medium Journal, 28-spline -15 lbs. ea.

3. Brakes: Small 10" x 1¾" Drum Assemblies - 22 lbs. ea.

4. 3rd Member: Reinforced Revision 8.8-inch Case - 60 lbs.




9-inch Rear End Assembly Weight: 194 lbs.

1. Housing: 38 lbs.

2. Axles: Large Journal, 28-spline - 18 Lbs. ea.

3. Brakes: Massive 11-1/32 x 2½" Drum Assemblies - 26 lbs. ea.

4. 3rd Member: Conventional Diff. - 68 lbs.
a. w/Traction-Lok Diff. - 71 lbs.

(24 lbs. Difference Between Drum Brake 8" & Drum Brake 9" Rear End Assembly).


Versailles Disc Brake Rear End Assembly Weight: 215 lbs.

1. Housing: 39 lbs.

2. Caliper: w/Pads, Anchor Plate & Flexible Brake Hose - 24 lbs. ea.

3. Axles: 20 lbs. ea.

4. Rotors: 10 lbs. ea.

5. 3rd member: Conventional Diff. - 68 lbs.

(45 lbs. Difference Between Drum Brake 8.8" & Disc Brake 9" Versailles).

If you are concerned about the weight ... a aluminum center section saves 20 lbs.

Part of what makes the 9" so strong is that there is more interface between the pinion teeth and the ring gear teeth. This should result in more parasitic loss with the 9" (anecdotal evidence by stranger's postings)....guess someone will have to man up and do a before/after dyno to get at data on that one.

The 3rd pinion support bearing also adds to the strength of the 9".

But... that high offset pinion is terrible from a friction/powerloss standpoint.

Dude dyno'd 901 hp through 8.8 in another thread, I was sold. I doubt I'll break it with my turbo 2.1.

I've seen about 5 ford 9inch pinions on the ground on the laundry h pad. Never seen that with a 8.8. physically bigger does not mean it's better.

LOL well, you won’t break it. On the other hand, you may not be able to rotate it.

I think a lot of people get lost in comparing the 8.8" and 9". While, technically, the 9" is a "better axle". That does not necessarily make it better for the application; especially when cost of entrance is taken into account. An 8.8" is easily modified and installed by a proficient DIY guy in a weekend and can be had with a number of gear ratios and with a limited slip plentifully for $150-200. A 9" is going to take a lot more dough and a shop putting it together for you to make it happen. To get one around the Volvo with and set up well is going to take a cut down housing set up by a shop, a pair of custom axles, a third-member with gears and a carrier of your choice, and a custom brake setup (iirc, not a whole lot of factory disc brakes compared to drums. A guesstimate of getting a 9" into the back of a 240 is $1000 on the cheap side of things, realistically more like $1500-2000.

You're gonna spend 5k for a 9 inch that doesn't grenade. Or 120 bucks for a complete 8.8

You're right on the money with the estimate.
I priced this out last year through Speedway Engineering: http://1speedway.com/?route=common/home

Having a shop build a "drop-in" 9in for a volvo 240, with the aluminum 3rd, and a clutch-pack LSD was $1850.
Same width, axles drilled, and wilwood brake brackets, but no 4-link mounts.

But that's with all new parts, so not too bad. It's just $$$ right?

The fully rebuilt Toyota 8" going into the rally car was ~$1000 all said and done.

The ford 8.8 going into the drift car is about $500 so far, and that includes a new LSD and diff rebuild kit. Would have been much cheaper if the LSD hadn't been ran with a loose cross-pin for a while.

yep, I'm at probably $350 for my 8.8 with an LSD rebuild kit, new axle bearings/seals, and a fancy cover for it.

I will probably use 9" axle housing ends with the Oldsmobile bearings to keep the oil in, in my AutoX Hoonmobile.

Really depends on use, the nine inch is handy as you can have several third members set up for different tracks instead of trying to setup a Salisbury type rear. I doubt anyone here needs that feature really...There was a time that the nine inch was cheap and easy to find too around the time when 455 buicks and 472/500 cadillac and 428 pontiac engines were there too, and good luck finding a disc brake Lincoln 9 inch, they were rare 30 years ago. Some have argued that the third bearing was a crutch to fix a design flaw because the pinion bearings ended up so close together? But i dunno....and I thought i read somewhere that the height of the pinion I relation to the center line of the ring gear adds strength at the cost power to turn..but I can't revert either...Just give me the cheap stuff..I run a 12 bolt in the 65 and Dana 60 inn the charger..A friend of mine converted a full floating 14 bolt truck rear end to give lug to use in his 65 impala
