BenJ,
These pic files are too large to post here [6-700k each, pm me your email and I'll send them direct if you want them They're nothing flash, as I said I only wanted them for a visual reference for the EB setup on an EL Diff.

Ok

I had already put one replacement diff in the EB earlier this year. It was just a SS 3.27 diff I had in my spare car. The original diff was making complaints and now resides under the parts car. I borrowed some parts from it to get the EF diff ready to bolt in.

I spent yesterday and today cleaning parts and preparing the EF diff to go into the EB.

This is what the backing plates and dust sheilds looked like AFTER I degreased and steam cleaned them.



After some work with a wire brush and my dremmel they turned out like this.




I was surprised to find out the backing plate was made of aluminium. For some reason I thougt is would be cast iron or something. Oh Well.

I then removed the 4 9/16th nuts holding the axles in and backing plates on and popped the axles out (use the discs on backwards with some nuts and use them like a slide puller). I installed the EB backing plates and put the axles back in and tightned the nuts up a bit at a time until it was snug.

I then installed the brake lines as the EF use a different arrangement. First I removed the EF handbrake cable. Then undo the breather from the left hand axle tube and install the brake line junction from the EB. I had bend the brake lines a little bit to route them through the old handbrake brackets. I used cable ties to keep them secure.

Pics of it ready to install tomorrow. icon_biggrin.gif






Once the diff is in the car, I will mount the current calipers and discs on and it should be good to go.

I also purchased the correct speedo gear from Ford for $14.

Will let you all know how it turns out.

BenJ,
Forgot to add in the e-mail, these pics are so much better than my much abused Ellerey's. It's also good to know for sure that I can swap in the ABS axles from the EB2 if I want to.
Cheers

Hey Paul

Didn't your EF diff have ABS axles? Mine does, but my EB doesn't.

I presume then that your EB has ABS fitted?

As far as I know you can swap axles from EBII onwards as they are all 28 spline. As I understand it, early EAs at least had 25 spline axles and therefore are not compatible.

From what I can tell from your photos, there is a small black box looking thing on the backing plate behind the disk, and I think that is the ABS pickup. Just pull one of the discs off and you should see the ABS ring on the axle.

Let me know how it goes.

Ben,
Yes it has ABS standard on the XR6 diff. and is fitted to my EB2.
Sorry I wasn't very clear, the ABS on the EL is a later version and I don't know if it is backwardly compatible to the EB2 modulator. I should have added an "etc"after axles in my post, the axles are interchangeable to my knowledge, it's the sensors [pickup] I'm unsure of, I'll soon find out. This is actually the first time I have ever had more than the most elementary contact with ABS, usually just removing and replacing like items, so its alearning experience for me.
Cheers
Paul

By the looks of that diff hat its a EL one. So the Watts Linkage point is lower and will reduce a old flacons body roll a whole heap.

Well It's in. icon_biggrin.gif

And I think it has a buggered pinion bearing. icon_cry.gif

I fairly howles like a banshee.

I wil take it to a diff place in the morning to see if they can diagnose it. And yes I did check to see if it had oil in it. Does anyone know if you have to dissassemble the diff to change a pinion bearing?

The only hiccup I had putting it in is that the EF/EL diffs use different swaybay brackets, and I had to make a trip to the wreckers to get the correct ones.

Will let you know what the result is.

MATE !!! Checkthe Diff Angle. It could be out. You may need 350mm upper arms to straighten the Diff and Axle length so its all level.

Does it Howl and Vibrate.
I had that problem with my conversion.

No vibration, just noise.

The car is lowered, in fact I installed 10mm spacers when I put the diff in to raise it a tad. As it is an EB, I am not sure if I can install the shorter upper control arms and bracket.

Should and LSD be difficult to rotate by hand? My single spinner rotates far more easily than the LSD does.

Now my diff was sitting for a number of years, and I suspect that the outer pinion bearing may have dried out/coroded during this time.

I guess I will find out tomorrow.

put it on axlestands. but put the stands under thediff to similate the car being on its wheels
and then stick it in drive and slimb under and have a look at everything.

Did you change the diff oil ???

im thinking shorter upper controlls to str8en it up.

normally a bearing will be okay evean after sititng a few years.

Ive seen a car started after just a oil change thats been sitting for 20 years. it drove flawlessley

Sorry,

Yes a lsd should be difficult to rotate because its driving both axles.

but if you feel slight grinding feeling it could be a bad bearing.

Thanks for the reply.

No I didn't change the oil, and I am relunctant too until I have had it diagnosed tomorrow. If they take the hat off to inspect it then I am just flushing money down the drain.

It did feel a bit rough when turning it over by hand so am thinking the outer pinion bearing.

Worst case, I will take the diff back out and put my old one back in. I am driving to QLD next week, so need to be sure its all good. I would rather sort it out when I get back.

Regards

Oil is cheep. Diff centres in the LSD flaviour arnt hehe.

In the morning I will put it up on stands and see if I can isolate/identify where the noise is coming from before I go see a couple of Diff places.

The little bit I drove it, it certainly feels more lively than the 3.27. Oh Well.

More news tomorrow.

Well, I saw a diff specialist this morning and it needs all new pinion and carrier bearings, about $460 to fix it.

So I pulled it back out of the car, second diff swap in two days, and put the old one back in.

I will put the XR6 diff in the garage until after christmas and look at getting it fixed then.

BenJ,
Sorry to hear that mate, wasn't game to comment on the screeching in case I jinxed you.
Might not suit you but check out what Bunter's got in this list, he doesn't mention any ratios but $250?

Hi Paul

Never mind. My primary concern is my trip to QLD next week. The car needs to be 100% for the trip, and my funds are allocated already.

Here is a link to the Australian Ford Forums site and my build thread. If you are not a member there you should join as it is also a good source of information.

http://www.fordforums.com.au/showthread.php?t=11191441&page=1&pp=25

I will wait until next year when funds will be available and get the diff fixed then.

The Diff Bunter has is a 3.27. I have one of those in my wifes ED Ghia but it needs servicing as it spins one wheel. Thanks for the heads up tho.


Regards

Have a safe and happy trip,
I'm also on AFF and have been watching your thread. I hope I have more luck than you, although this diff was running OK recently. I think I'll finish putting the EL engine in the car, run it on my old diff to make sure all is well, then pop the LSD in next week. We also have to visit family in Qld before Xmas and understand your position. I would prefer the LSD in for that trip but the std one has been there many times and is a good standby as is yours.
Cheers,
Paul

Hello once again.

I finally have an update for this thread.

The diff has been dropped off at a diff specialist. They looked at it for free and even took the hat off and checked the teeth for wear etc. They said the LSD needs shimming etc, which I expected, and bearings.

So for $480 they will put in new carrier, pinion and axel bearings, and service/shim the LSD centre, setting it all back up again.

Should be better than new.

I will be picking it up next Wednesday afternoon and Paulmac hopes to come down on the Friday and help me put it in. While we are at it I hope to be able to do something about the pinion angle with a bit of parts swapping.

Will post how it all goes.

Cheers
BenJ
