Ford 9"

[foxriderry]

ok so today I dove in and order my ford 9" axle housing from quick performance, ive yet to order the center section yet, but id like some opinions on whether I went the right way with it or not. Im mainly looking for a street/strip car, right now its a 6spd heads cam ls1 Camaro ss. I may go to a turbo in the spring time, I guess that depends on the bank account and transmission. Here's what I ordered

QPF9F9HA QP GM 1993-2002 F Body 9 Inch Housing & Moser Axles
Housing Center Piece: New Fabricated (light & strong) - $100.00
Housing Ends: Billet GM Flush (with seal surface for GM 93-02 F body disc brakes)
Moser Axle Spline Count: 35 Spline
Moser Axle Wheel Studs: 1/2"-20x2"
Gundrill Axles 35 or 40 spline only (lightening): No
Star Flange Axles (lightening): No
What year is your car?: 2002
4 Channel ABS/TCS rings installed: yes - $200.00

im gonna go with 4.11's for the center section, im not sure if I should go with a spool or what so any input on that would be greatly appreciated

also not to sure about axle seals and bearings, im not sure if the axle comes with them installed and what not, so any input on that would be great

quick performance says that their centers come set and ready to bolt in but I think it would be wise to check backlash however, im not certain how to do that so maybe when the time comes someone could help me out?

I think that's it as far as worries, its another learning experience for me and I cant wait!!!

[BonzoHansen]

no spool on a street car.

[foxriderry]

hmmm ok so than an eaton truetrack? mind shedding some light on a spool and why it wont work? just for my knowledge, I trust your judgement bonzo

[BonzoHansen]

Spool are great for drag racing. Not much other kind of driving.

Spools do not allow the back wheels to rotate at different ('differential') speeds on a turn and thus can cause potentially dangerous problems turning, worse if the pavement is wet. They also stress wheel studs on turns.

There are guys that will say that is all crap, spools are fine. I politely disagree based on my experiences and the professionals I have talked to over the years. Not anecdotal stories from the internet. YMMV

Give percentages how much street vs strip. 50/50? 99%/1%? Be honest. Also no auto-x intentions at all right, true street/strip?

[foxriderry]

no auto-x for me cant afford that sport haha, but no its probably more street than strip, id say 75/25 although that may change now that I wont have a rear to worry about, but im probably gonna go with the truetrack I think between the gears, and the not worrying about my rear exploding im gonna be happier than a pig in ... yeah

[BonzoHansen]

I think you'll be happy.

[B4C]

The eaton got some pretty bad reviews lately. Quick is going to try and push the strange center section, get the yukon. It's beefier, the main caps are bigger, and its the same price. I got that with 4:11's and a wave track. IMO spend alittle more and get the wave track, lifetime warranty, drives like stock, strong, acts like a spool when locked.

[sweetbmxrider]

Ya you don't want a truetrack with an m6. Detroit or wavetrack are what you should look at.

[foxriderry]

sweet thanks for the input guys!

[B4C]

I got the same rear your looking at ordering. I dropped the center right in with no issues, wines alittle bit but that can be expected with 4:11's. They say to use only rtv, mine leaks, spend $20 and get a lube locker gasket. If your going turbo you might want a different gear ratio.

[LTb1ow]

Gear it for what you have now, not on the future dreams you have.

A turbo gear will suck without the turbo part.

[Dudbird113]

Eaton or no posi says my engine builder

[foxriderry]

ok cool thanks, it looks like swapping gears in a 9" would be a lot easier considering you can pull the whole center section, as far as axle seals, and what not in the tube, b4c, did you notice if the housing came with all those? I don't mind buying the extra stuff, but I don't wanna buy it and find out it came with them. was everything installed? all you had to do was bolt the center to the housing? and obviously attach brakes... im just trying to get all my ducks in a row so to speak

[foxriderry]

oh... and if the jeep sells for a moderate price, the turbo may be happening sooner, can anyone shed some light on a good turbo gear for me? :help:

[LTb1ow]

3.08 - 3.54 range pending turbo size, redline, and trans..

[foxriderry]

ok cool im thinking about getting in on the tech group purchase, im not sure if im allowed to say where there buying from though... so ... yeah

[B4C]

Eaton or no posi says my engine builder

There's better choices, anything is better than the eaton with the clutch packs in it...

There are o-rings on the axle bearings, no need for the axle shaft seals. Just put some vasoline on the o-ring so you don't roll them, I also put some rtv on them to be safe. You have to install the studs for the center section, and drill the shock mount, and Panhard bolt holes alittle bigger. Only thing other than that is to install the backing plates and axle bearings. I got mine without abs so idk if your going to need anything for that.

[BonzoHansen]

I've heard about issues with carbon fiber clutches our something like that. Is that what you are taking about?

[B4C]

No, why buy a posi with wearable parts when you can buy one with out. Like a Detroit locker or wave track

[BonzoHansen]

i don't see where eatons wear out very quickly, and clutches are rebuildable unlike say an auburn.

A Detroit locker is good for a street/strip car. The yukon stuff we have used has all been good.

[foxriderry]

yeah i added the abs option cause thats what my car has on it now, did it come with any directions from them by chance? i guess that sounds kinda dumb but idk my way around axles that well

Strange has one comparable to he wave track too that seems pretty good. Me personally I would just rather not be bothered with it. The eaton in my car the clutches wore out in about 3 years.

I don't remember I think there were some torque specs and patterns, it's not that difficult to assemble pretty straight forward. I could lend a hand if your close enough.

[Dudbird113]

if were worried about stuff wearing out just get a spool. **** I know people that drive spools in the rain with slicks

[sweetbmxrider]

wut

[B4C]

Thats why I got a wavetrack.

[Sprayed 99]

Detroit locker. Bullet proof. I loved the one i had in my TA. Spools take some getting used to but they're not that bad on the street.

[KingPin1094]

I have a 9" in my camaro with an Eaton Truetrac and 4.11 gears. I like it, besides the mild gear whine. I really just wanted to share this video of how the Eaton Truetrac works, the video is well done and it easily shows how it works.

I've had nothing but problems with my Wavetrac. I recently sold it to a member on here who will hopefully have good luck with it.

With that being said I will never mess with an LSD again. How much street driving are you planning on doing? Spools really are not bad on the street at all, most of the people who say that you can't drive them on the street have never actually driven them on the street. If you're not looking to rip through every turn and you know you're not going to autox/road race just get a spool and never look back.

[foxriderry]

i dont do that much street driving, its mostly just leisure driving on the street, but i dont wanna lose the ability to give my car a "spirited drive" now and again so im still up in the air.

In other news i got the axles in the other day, which is pretty exciting. The bearings/seals (not really sure which they are) fell out of the packaging inside the box, so i hope they're ok. It didnt really come with instructions on how to install them on the shafts. Do they even go on the shaft or do they go on the housing?

They get pressed on the axle shafts, put the backing plates on the axle shaft first!

No issues with mine, I love it. Drives like stock around town, acts like a spool when locked up. I followed the break in instructions and fluid recommendations to a "t" tho.

Doesn't seem like there are many issues with them which is why I was so bummed when it failed on me twice.

How often do you race the car and what's your setup?

[foxriderry]

so i bit the bullet and went with the wave trac ... again no instructions really =/ what fluid did you use in yours b4c? and what kinda break in and other pertinent information do i need to know (if you dont mind me picking your brain).

In other news i also ordered an sjm linelock/abs delete kit, a straight throttle cable and a bmr tunnel mount torque arm with d/s safety loop.

Next on the list is tires, im kinda tossed between nitto nt05r's and some E.T. streets, so any input is always appreciated.

I used non synthetic with no lsd additive...could only find it at advance auto. The gears came with brake in instructions.

[foxriderry]

well provided i get my new driveshaft by saturday the install will be going on this weekend. I have a buddy coming over on saturday to lend a hand, but hes leaving around two. If anyone else is interested in getting their hands dirty feel free to pm me, ill send you my address. There will also be at the very least one case of yuengling (probably more) and I would be happy to share with anyone who feels like getting involved.

Your going to have to do some drilling...shock mount holes are too small, as is the hole for the Panhard bolt. Depending on your torque arm you might have to do some grinding on the mount...

[foxriderry]

ok, thanks for the heads up. That's kind of bothersome considering the fact that the housing is designed for my year car, and the incredible amount of money i paid for the thing, i would think it would all mount right up. I guess we'll see what happens when i get their.

[foxriderry]

anyone have any input on how much of a difference it will make not having a rear sway bar in? im up in the air on purchasing the mount kit, especially because idk the dia. of the stock sway bar, or the axle housing.

[foxriderry]

Ok so just to update, I got the rear up under the car and have the lca's bolted on. Still have to drill out the holes for the shock mount, and PHB.

As far as the brakes go, the line lock is all installed, just needs to be wired up.

The tunnel mount torque arm was giving me problems because the bolts wouldn't thread in, so I wound up tapping out the holes to 5/16 x 1.25 thread. Now I just need to locate some 5/16 fine thread grade 8 bolts (proving to be a hassle) and that should slip right in ... hopefully.

If anyone is ever in the area, and feels like turning some wrenches feel free to send me a message and ill send you my number. This install has been quite a pain considering im doing most of it solo.

Is there a Fastenal near you?

I get most things within 2 days or less. http://www.mcmaster.com/#

[foxriderry]

not sure about a Fastenal, ill look into it, and thanks blackbird, I'm hoping to locate them locally as I would like to get these problems done and out of the way today... but if not ill be ordering from online.

My only question is that the tap I used was, like I said, 5/16 x 1.25 thread. Apparently 1.25 thread is a metric measurement. I'm pretty sure that that would convert to fine thread in a standard bolt, but if someone could confirm my suspicions that would be great.

[LTb1ow]

IDK what the "x 1.25" means, usually that would mean you want a 5/16 threaded bolt, 1.25 inch long. It wouldn't make a lot of sense ot have a STD thread mixed with metric denoting

Any more details on teh tap?

This fit the bill?

I am assuming it's 5/16" -24 x 1.25

[foxriderry]

that does seem to fit the bill, I found a trucking supply store in Elmwood park that says they have what I am looking for, looks like ill be making a stop their after work.

the tap merely says 5/16 x 1.25. I can only assume the 1.25 is referring to the pitch of the thread. It is a blue point tap kit, so its not a cheap set.

[foxriderry]

So i have another update on how things are going.

The rear is all the way in and bolted onto everything. The only things left to do are to install the drives shaft, measure and adjust the angles, and install the brakes. Ive learned my new rear didn't come with provisions for the brake line brackets, so I'm gonna have to do some Jerry rigging to get it all hooked up. I'm hoping down the road to weld it to the housing, unless anyone thinks that's a bad idea. One way or another i hope to have the car off the stands and driving by tomorrow.
