Will an e-series diff fit into an au?

Falcon87 · 12-12-2007, 03:45 AM

As above...

Would an e-series diff fit up into an AU?

My friend just installed an EB LSD into hes EF...The only thing we had to change was a little section of the brakes, which was nothing anyway!

Thanks...

If you fold the rear seat down you should be able to get it in the boot!

The brakes are different, particularly the parkbrake. Unless your AU has IRS, it will likely fit, but they are a different width, hence different offset wheels. I would expect a diff from the wreckers would be close in price for an AU to an Eseries.

the centre will fit into an AU housing but it would cost more than it was worth to get them changed over as stated the offset is different on the AU that id why pre AU have different wheels so this will have to go into the too hard ( or costly) basket

Why not just Buy an E-Series dude .. your car has Enough Parts from one now ..

^I agree, you are downgrading your au. So just buy an e-series!

StealthAu · 12-12-2007, 12:28 PM

I'm pretty sure the AU's have the same centres as the E series or atlease EF EL. So in what way would using an E series Diff be downgrading?

you would be changing the rear track and impacting on drivability as stated above these have a different offset also the brakes are different AFAIK

Hey I realise what you are saying, I missed a word out of my post, last line should have said "So in what way would usin an E seires diff centre be downgrading.

blackers10 · 12-12-2007, 12:48 PM

im told the diff centres are the same from EB-AU live axle
but IRS has a wierd little groove in it that holds the driveshafts in (its for a circlip)

the 4wd systems LOKKAS(used in 4x4s and completly road legal) can be bolted into the stock open center and give more power handling than an LSD does..
but not QUITE the same effect as an LSD(no real slip.. but does open on cornering unlike a minispool or locked diff)
they only cost about $500 too!! + fitting
an au is just a series 10 EB anyway.. most of the driveline isnt that different
good luck mate!

yes you'll notice i mentioned the centre earlier in the thread i also said by the time you pay to swap them over it would be too dear. and if you don't have the equipment and the experience to swap a diff centre don't even thing about it unless you like wine ( whine) and clunks

blackers10 · 12-12-2007, 12:59 PM

on the other hand
you could possibly run some WICKED dish on the rear hehe

but then it depends if it fits next to the suspension
and then you are changing track by more than XYZ% that makes it illegal anyway

If you were looking to upgrade your single spinner with a second hand limo, a low kay centre out of an E series would be just as good as one out of na AU. As far as tools required, to swap a diff centre all you need is a socket set and a set of axel stands.

to just bolt the centre in yes but to adjust it and get it running right no. thats why so many lsd conversions fail " experts" who thing the can " give it a go"

Falcon87 · 12-12-2007, 06:18 PM

We'd be swaping the diff's over our selves...Have already done it on an EF!

So in conclusion will an e-series diff fit into an AU1? I know the off set is diffrent, which isn't that big really...

FGII-XR6 · 12-12-2007, 07:07 PM

are you talking about swaping it housing and all?

Sorry, I'm not trying to stirr crap here, but what adjustments are required to an LSD on fitting? I realise if they are not in great nick it is a good idea to get them reconditioned, but after fitting at least a dozen LSD centres to verious cars successfully, I would be interested to here what adjustments I should have been doing.

FGII-XR6 · 12-12-2007, 07:49 PM

the crown wheel and pinion need to be lapped in when u change housings also as i understand it there are shims involved too i have heard a lot of home built diffs and they all whine or clunk or both

No. Swap the centres, but not the whole diff. Besides the width being different, and brakes being different, suspension pickup points are also different, and the handbrake mechanism, while based on the same idea as EF/EL is different again in the AU.

Why not try putting the EA Dash into the AU .. that could be fun ..

or Moulding an EA Front Bumper to the AU for that Awesome "Oh nah , its Rustic" Look ..

He he he, while you're at it some EA front seats and how about a 3.3/2L(whatever it was) EA CFI engine.

Why do people have to be smart ***'s when im simply asking questions...

BLACKAUXR8 · 13-12-2007, 01:43 AM

Short answer is NO it wont fit. The suspension mounting points are different. If you cut the suspension mounts of and re-weld them maybe it will fit. Then the suspension mounts will probably snap as there under a fair bit of load so you'd want to be a good welder to pull it off. In my opinion its to hard and to expensive

you would never get it to work ( re welding the mounts) as a home job the alignment is critical. the car would crab up the road and there is no adjustment

Was only stirring mate .. calm down .. but admit though .. why the hell would you put so many E-Series Parts (Allbeit there cheap ..) on your AU when the Replacement Parts arent that much Dearer ...

There was a Reason the Trans And Diffs Have a Slight difference , BECAUSE THEY WERE UPGRADED ..

Hmmm....How were they up graded from an e-series? It's the same BTR and Borgwarner concept

FGII-XR6 · 13-12-2007, 12:15 PM

car parts evolve often in small ways that may seem insignificant. during the life of a car ways are found to improve things and these are adopted as running changes . what may seem a minor change to you is something that had been identified as an isue by ford. it would be cheaper to make no changes but not good for the evolution of the car itself. using older model parts is downgrading the car and in some cases may be illegal as it may impact on ADRs emmisions or other critical design features. since the BTR was introduced in 1990 there have been a wide range of changes and today BTR bears only some resemblance to the original 1990 model. the borg warner diff was also used in the XP but is nothing like the diff in tadays cars. your statement that It's the same BTR and Borgwarner concept would be like saying an XP falcon is basically the same as an XF as the use the same floor pan/ sub frame and are both falcons . if you sell the car in the futuer and don't tell the new owner you have downgraded it with old inferior parts you open the way for litigation so i would think before i turn the car in to an e series

blackers10 · 13-12-2007, 12:22 PM

so blksam
ring up your local ford dealer..
and grill the service technicians and say look how different is the earlier diff center over the AU item??
then you can prove to the world its different or the same..

but for sake of saving money.. just do it.. if it breaks.. it cost you 1/2 the price

as by the sound of it you have access to alot of E series parts for a damn good price!

good luck dude

Thank you man!!! Amen to that lol!

U have an EB trans in ur Lane dnt u?

StealthAu · 13-12-2007, 10:08 PM

The centre is the same, there is no question. If your centre is rooted and you have an e-series one slap it in, no issues. Except gears, I think they were a bit shorter in the early E povo packs

blackers10 · 13-12-2007, 11:58 PM

i had an EB box in my lane yes

but now i have a strengthened AU item as the EB one has a solinoid issue and this other box came up at the right time for the right price so i grabbed it!! its about 1000x stronger than the stock box etc etc

good luck have fun
