2.0 Axle on a 2.8I

[fordperv]

Have to agree with terra the ratio doesn't equate to its strength, I gave my 1.6 axle a severe pasting with a hot 2.0 pinto did it have any problems............... No

[chris_v888]

i tell you all what do it your way as you must have so much cash to burn i still say use the right thing yes built the same diferant rashios? but you will be quicker off the mark but no top end and use that bit more fule ok end of all this crap now ive most probaley forgot more than you know ok

[Terra-Kotta]

No need to get your nickers in a knot

[Major_Tom]

Cooool your boots, its all good.

With regard to ratios i run a hot 2.0 through a 3.77 1.6 axle and thats all good.. never really noticed any loss of top end. Mine still goes 115+ in 4th gear without screaming too much. On that private road that we all use lol.

Just a quick update, I have found that i have this type of diff see image below.

(This is not an image of my actual diff - This is just for reference)


Hopefully you can see where the red circle is in the centre! This is the pin that has snapped in half on my diff. I have since purchased another second hand diff of the same type for £39 which i thought was fairly cheap. (It appeared in good nick i,e no broken teeth)

My farther decided to replace the diff whilst i was at work so i didnt see how he did it (he is far better with a spanner than me however he or myself are no F1 Engineers). In short he told me pulled out both the half shafts and just replaced the diff using the same bearings that come on the replacement diff not the original bearings.

However since then we now have drive which is a start i suppose but now have a large Whining / Buzzing sounds which does not sound healthy! It is familiar to a dodgy wheel bearing x100 so at present i wouldn't dare drive it over 10mph it really is that loud.

To be honest i think we are going to have to admit defeat and send it in to somewhere that actually know what there doing. I Would like to know what you lot might think is causing the sound we don't think it is the half shafts we think it might be the large pinion that turn the crown wheel and that may also be the reason the initial diff broke.

Thanks in advance!

Hi I rebuilt my 2.8 axle with lsd using new bearings and a 3.44 cwp reading up on information from the net but you do need certain specialist tools and knowledge. With the 5 speed box I think the 3.44 ratio wakes the cologne up a bit and will still pull similar top speeds but at higher revs. If you change the axle ratio don't forget the drive gear in the gearbox for the speedo.

It needs setting mate for lash. I have done one with help of Simon race on here but really it's specialist job.

[Terra-Kotta]

Personally I'd put that 2.0 axle in and enjoy the extra go

[Wilky]

As I'd said previously, it's a specialist job to change. The difference between getting it right or wrong is hundredths of a millimetre

The backlash and pre-load must be set.

After reading about the classic ford project injector its my understanding that ford fitted the sierra XR4I with the same ratio as the 2.0 Capri.

hence why they fitted their 2.8I Capri with a 2.0 axle, they did swap in the 2.8I half shafts and rear brakes.

Its a direct swap over all, however I have lately found them to be a bit heavy (but that might be due to my back injury).

anyway as said the top end speed will be lost but it will be faster off the line.

However I have no idea if ANY of the bearings in the 2.0 axle are the same as the 2.8I
ones, so that would be worth checking if the 2.8 ones are "better" so to speak.

But it kinda is away of making the car that bit quicker with out having to declare it as ford were well known for bodging the last of the Capris.

[Terra-Kotta]

You won't loose any top end. It will just rev higher. Unless you drive round at 100+ everywhere you won't even notice.

I've been in a 24v V6 with a 1600 axle. And that was a 4 speed!!!!

Also bare in mind the 2.8 has the crappest type 9 known to man with a second gear longer than London to Brighton.

[QuadCamCapri]

As Glyn and Wilky have already said only difference in the axles is the ratio, including halfshafts which are all the same.

I built a 3.75 LSD for my Cosworth BOA with 224bhp, and also a 4.1 with a Quaife LSD which was fine with a 300bhp Essex, although I did eventually break a halfshaft whilst leading a race at Brands, then changed to Quaife ones.
Will soon be using same axle for a few races with a V8 which will be around 450bhp to start with, until I have time to change all the running gear, and the engine heads north of 500.

It did rev quite well didn't it

For a non pinto haha

I would have liked to have been there when you said to your mate "floor it" and he knocked it down into third!! Change up!!!! Change up

Yeah as we were doing 6k in 4th I was a bit surprised

Hi

Quick Update, I purchased the 2.0 atlas axle in the end as it appears to be in really good condition and have been guaranteed it works a treat. It also came with the brakes and anti roll bar which is an added bonus. The axle looks the same so i imagine it should all bolt up nicely.

I wont get to the car until this weekend as i have left it at my sisters. Is there anything else i might be missing before putting it back together? Also i am hoping where the propshaft connects to the axle the same?

Oh and i all ready have some new u bolts for putting the axle back on.

Thanks in advance.

Heath

No. The brakes are different. Fit your old ones, you'll need to remove drive shafts to swap ALL the brakes over.

Other than the brakes the Axle it the same. Gear change points will be different. You'll hate the shorter legs at first but give it a few days. It will feel lively.

Just thought id pop in and say i have a 2.0 axle on my 2.8 fitted it myself.

Same prop fits fine.
Rear drums are smaller, so you now need to buy 2.0 drums/pads etc
Handbrake will need to buy 2.0 handbrake cable.
Other than that, all fine no problems

Enjoy
