But I must say, these 4.30's are a PERFECT match to the gearing. 1st through 4th is brutal on the spine and 5th and 6th are flat out insane cruising gears. 2050 RPM's at 80!!

Probably just order up the same.

Didn't know what was going on? Everything on this car is only 5,000 miles or newer.

It worked for a while. I'll try one more time until money is flowing, which is almost never, or else the car sits. The leak was slow, and is suddenly fairly substantial. The stuff I used, White Shepherd, is made for pinion seals, among other things. I only used a tiny bit before. Now I'll use a bit more, with fresh Royal Purple.

Seriously tho.... One of my axles leaked fluid for a good long time... just monitored and refilled a couple times till I could afford to get it fixed.....

True, you really don't know what you are in for until you pop the cover, but if you aren't hearing any clanging around back there, it might be as simple as re aligning the pinion & new seals/bearings... Hopefully that's all it is.....

[justbob]

Well fluid was full, the spiders were MINT, as well as the clutches. Zero teeth left on the pinion, looks to be 11 sheared on the ring.

Ford racing over already enroute, new gear set to be ordered soon. Just need to pick a smaller set to ensure a bigger diameter pinion (that sucks...) and button her up.

Guess its time I learn this gear thing or at least try to..

When you replace your pinion, you can replace the crush sleeve that normally goes onto the shaft with a solid spacer, under extreme load these spacers crush more than they should and leave your pinion bearings loose.

I did actually see a pony with a 8.8" solid like ours on the lift at a dyno shop last summer that was leaking right between the housing and the pumpkin. Car had just a tad over 500rwhp and was twisting the housing on launch. They ended up welding them and it helped.

[justbob]

Finally time to get this girl back together, although a band aid, the best I can currently afford. May just be a little easier on it and start saving for a custom 9".

Ordered up a 4.11 Yukon gear set to help increase the diameter of the pinion over the smaller 4.30 set, 5 quarts Lucas gear lube, 2 Ford Racing FM's (enough oil for changing it out again soon), new pinion nut, ring bolts, solid spacer kit, Ford Racing girdle cover (thanks Derrek!) and a dial indicator. Also ordered a new Cobra IAC to address the hanging idle issue.

Still need to round up an inch pound dial type torque wrench on the cheap.

Thanks Chris, for one I have never heard of solid spacers, and for two, you were right! I finally got in the mood to yank the pinion tonight and found the yoke to be loose as all get out!

Plus the oil slinger wasn't installed the last time? Is that common or a simple mistake? I'm sure that both of those reasons contributed to the constant drip since a couple weeks after install.

Anyways, I took your advice and ordered a solid kit with the 4.11's last week. Probably have the stuff tomorrow or the next day and in late week depending on other duties. Plus I will probably just have to buy yet another install kit.. So much for budgeting.

That was a bad mistake and was the leading factory to the early failure to the rear - especially if it was left out of the final assembly AFTER the test fit w/the corect shim pack for pinion depth! Constant drip would have been from a loose pinion shaft/deflection.

Sounds like you got the right parts for a solid rebuild. Might want to use a different installer!

Figured as much. Regardless, I wouldn't throw sticks at this guy, he has always done me real good. God knows I have made my share of mistakes, we all have. It does suck considering current total of parts is right at $500 plus the $129 tow (that State Farm is covering, hopefully all of it)

Work has been slow added to the cost of another tow, I found this to be a good time to dig in and learn this. I already made a sweet yoke holder, ordered a dial indicator with base, and a 1/4" beam type torque wrench i'm borrowing till I find one I like and can afford, I kind of like the dial type, but pricey. Everything else I own. I just never took the time to look into setting up gears, but not really seeing what the big deal is? Just one more step to the countless axles, bearings, spiders, and clutch packs I've done for years on quite a few.

Pinion depth measurement with the digital caliper and old bearing is the only thing I seem to be confused on so far? The 8.8 rear is supposed to be designed at 4.415? I'd have to check my notes. What math do you do with that and the caliper measurement from end of pinion to top of bearing?

Anyone? Bueller?

For pinion depth I got a tool from ratech. Then if you get gears other than ford racing they usually have the pinion dimensions engraved on it. ratech tool (http://www.summitracing.com/parts/rat-10006) On my old bearing I honed it out so it slides on nice and easy.

Its not a huge jump with the .50 soaking up so much. Higher RPM in the lower gears you'll notice a difference. I love 4.30's. With your car/trans. I'd throw in some 4.56's. I just don't know if that 6th will do you any good, especially if you're running aftermarket cams and you are out of an optimal cruising tq range.

I agree 100%. I am following advice from others on staying 4.10 or under simply for strength with the larger diameter pinion. The only difference I have noticed really is sooo minor but in traffic I don't have to give an entire car length before I start releasing the clutch. It still wants to get rolling super quick with every 1/4" pedal travel, but ever so slightly more controlled it seems.

I'm being picky, the car really couldn't feel any more sure of its self.

Its so bad ass. :beer: Btw another thing you could do to attempt gettting a bit more gear back is running a slightly shorter tire. The borderline truck tire sizes on these cars soak up gear like crazy. My little fox body with 3.55's actually turns the same RPM as my MM does with 4.10's. And it has a steeper OD!

I understand what you mean about the R/P sizes. 4.30's they do start getting pretty small.
