V6 Capri Diff Replacement

Hi All

I'm in the process of restoring a 1970 MK1 V6 Capri, now one of the parts to be totally replaced is the diff, due to the previous owner taking it for one last drive & lunching it......anyway I was wondering if any of you out there have replaced the diff with one from another bread of vechile, if so, how difficult was it & what did you use ?

Cheers
Blair

Re: V6 Capri Diff Replacement

Blair,
I have put a hilux diff in my capri. Had to have it shortened, and got the spring pads re-made to suit. I also moved my suspension inboard about 5 inches as well, but that is because i am going to have mini tubs, with a lot of rubber. If you keep the standard spring location, just find any diff that you want to use, and take it and your std one to a diff specialists, and they will shorten the new diff to the same as the capri item, and make spring pads the same as the capri ones. They will set up the pinion angle the same as the std unit, and also weld on the upper control arm mounts ( if you have them ) as well. All you need to do is find a diff that you are happy to use. The only down side to the hilux diffs are that the smallest ratio centre you can get is a 3.7 from a 2002 model hilux or newer. Most of the older ones are 4.1 and up.

A falcon diff might be a good choice if you are going to stick with the std v6. Just get on from and old xf at a wreckers, and have it shortened.

Re: V6 Capri Diff Replacement

I've got a standard Ford 8 3/4" in mine.

Shortened of course.

Should be plenty of those arround and lots of ratios available.

Re: V6 Capri Diff Replacement

I have a Borg Warner LSD out of an XB with XF axles in my Capri (XA-EL are the same width). What I did was had the housing narrowed by 93mm per side, had the right axle shortened 186mm (now the left axle) & used the uncut left axle in the right side. The reason for using the XF axles was that the XB axles are thinner in the middle than they are at the splined end so cannot practically be cut whereas the XD-XF (probably XC too) axles taper larger toward the wheels (as do XR-XY axles).

The advantages of doing it this way are that you only get to pay for the re splining of one axle & you end up with a diff that is a fraction narrower than the stock Capri item.

I tried the Centura route. It's a Borg Warner 78 not an 8 3/4
it has piddly little drums on it & it is wider than the Capri diff by at least an inch.

On the other hand the Centura front brakes are so close to a direct bolt up on the capri that it's not funny.
