Rear axle

[juanZ28]

OK so my rear axle or differential or how ever you guys want to call it just went out on me it doesnt get a hold of the gears all it does is my drive shaft just spins and makes a knocking noise i took off the plate that covers up the box and my gears are are grinded down
what should i do? should i just go with a stock one or should i put a different one on my car?

This!

Don't waste money on something that is a known problem in our cars.

You have an auto or a manual, how much power do you make and intend on making?

i have a manual and i dont know how much power my car is making and i want to try and get the most power out of my car as possible

whats the difference between the 9 and the 12?
and where can i get one at?

[allbaugh_04]

The manual is pretty hard on the 10-bolts so you should probably go with an aftermarket rear end as mentioned.

Moser makes both, the 12-bolt and the 9".

Plenty of other companies offer rear ends as well. If you didn't know already, they cost more than 2 grand.

9" is stronger, almost unbreakable, but I believe it is heavier and has more rotational mass (lose a little HP)

12-bolt is supposedly not as strong as the 9" but I've never seen anyone break one personally either.

You can get these a lot of places, texas speed, or go straight to moser.

Midwest Chassis makes rear ends as well. Just do a google search cuz there are quite a few options out there.

I've heard stories of 12 bolts breaking on M6 cars (But I suppose anything can break.) And you are exactly correct about the 9"... bulletproof but very inefficient.

[allbaugh_04]

Usually the autos go with the 12-bolt because they don't need a super strong rear and they have less rotational mass, so yea, that could be why they don't break as easily.

That and in an A4, you can preload the drivetrain for launches, which takes all the stress and backlash off the rear... as opposed to an M6 car where you pop the clutch and pop your rear end right out of the 10 bolt.

That's why they say M6 cars go with the 9" because it's a free floating carrier. At least this is what I remember while doing a little research for myself before buying my 9".

what is A4 and M6???

[TLS_Addict]

A4 = automatic 4-speed
M6 = Manual 6-speed

I have a Moser 12 bolt,i would STRONGLY recommend order whatever you decide to with straight from the manufacturer.another option is the Strange S60 which is quite strong.

Moser 9' or Strange 12 bolt.

[juanZ28]

A4 = automatic 4-speed
M6 = Manual 6-speed

ohh ok so i have an M6 then

[pajeff02]

Here's how it breaks down:

Strength:

Dana > 9" > 12 bolt

Weight:

Dana > 9" > 12 bolt

Efficiency:

12 bolt > 9" > Dana


Our car is an A4 that sees track duty. I went with a Moser 12 bolt, but in hindsight may have been happier with a Strange 12 bolt.

Dana=Strange S60
