the mk8 in america came with option of lsd from the factory, a local breakers to me (working stateside at the moment) has 4 of them, all 3:73 ratio, believe the mk8 is an inch or 2 wider than mk6/7, i'm trying to find if people would be interested, i'm sure i can get a deal done, and shipping not bad, i'm shipping an engine or 2 for myself, so can package, thinking i would sell them for £750 each, the axles are ford 9.75, so very strong, and lots of ratios available aftermarket down to 3.08 and lots of different aftermarked LSD's if not happy with factory, they are the same 5x160 as the uk

That's great info and offer. I'd be interested in a 3.73 will chat on your other thread.

No need to go get custom ones made.
On further investigation I've found the transit diff is just a DANA 60 with 35spline 1½" hatlfshafts.
Now there are a whole load of aftermarket options for this diff.
Torsen, Detroit, ARB, Eaton, etc.

Air locker, E-locker, mechanical LSD, friction LSD, geared LSD etc.

But as usual basically only available from Europe or states.

Not sure about this but.....

I used to own an Austin K9 military 4x4, these didn't come with a diff lock or LSD, weird but there ya go. One wet weekend I got stuck in clay-mud at a festival, towing a caravan. I was embarrassed, as you can imagine, having to be towed out by a Landover!

Anyway, once home and dry I asked about this on the HMVF forum. Apparently part of the military training on K9s was to apply a little handbrake (or brake peddal if in 4x4) which stops the muddied tyre/diff slipping and gives traction back to the other wheel.

I've since tried this on my MK6 and it does seem to work.

It does work, and is a dodge which is possibly well known to some of us older drivers on here.
I used to do this back in the seventies, to extricate my old Sherpa van from where it was parked with 2 wheels on a muddy verge.

Sadly it's of no use in my current Transit, but I tend to keep all four wheels on the hard stuff these days :P

i have 2 mk8 transit axles coming in from america but both already sold, 3.73 ratio, will be getting more as soon as i am back there working, i'm going to be bringing in LSD diffs as soon as i can find a supply, the mk8 axle is a ford 9.75 axle, early axles were 34 spline, and most the diffs sold are 34 spline or at least listed as 34 spline, i've been looking for a supply of used or cheaper new diffs, but it seems the 35 spline diffs are in short supply.

Hi bj928., I came to this forum searching for an LSD in 3.73 for my 2004 transit, in Australia. Are you able to confirm that this model uses a Dana 60 diff? And also No. of splines. I am interested in buying 1 from you, and would convert to disc brake if that is what is available. Cheers.

Did the order from Grippers go ahead? At that price + freight to Australia, it is still cheaper than I can buy locally. I am interested in joining an order.

@Airthies er al: have you found a company in Eu or US that can actually supply a locking Dana 60 diff center?
I've been looking for a few months, can find them in some of their lists, but so far have not found anyone who can quote or sell me one....
Maybe it might be better to find out which other vehicles had Dana 60 locking diffs originally and then go looking at wreckers....
I've not been successful finding any cross reference yet.
Cheers,
Joe

The US model Mk8 has them as an option....but they're a disc brake rear end, with yours being a Mk6 drums. The Mk8 is also a tad wider than the Mk6/7 rear end.

Not sure if they had the locking diff here in Aus as an option..??

Mk6 (which is the age your talking about) is a Dana but not sure which one as I've not done any research into that as they are drum braked and semifloating axle.
The Mk7 axle 2006-2014 is a Dana 60 which is such a common diff when you start looking, nobody lists it as the transit axle is not an a configuration that's used in anything else or in conjunction with a 4wd system, unless your some random chancer that recon's it'd go well with a ranger setup underneath a transit

Anyway, you can get any type of limited slip or locker you want for the mk7 axle as it's a Dana 60 with 1.5" 35 spline.
Of any locker or LSD there's two options, which have a carrier break of either 4.10 and up or 3.73 and down (don't quote me on those exact figures as I've looked at so many I can't be sure but it somewhere around there).

Personally I'd go for either an E-locker or a torsen LSD.

They should both be readily available in Oz, I definitely reckon an ARB airlocker will be as their an Australian company


The Mk8 is a Ford 9" diff apparently, which again is a fairly common unit to find aftermarket LSD and locking carriers for but I reckon it'd be easier to find a SH Mk7 axle for your van to convert before fitting.
And know it's pretty much a straight swap as it's not an uncommon upgrade in the UK.

@Joe in Oz
Here's one that'd for ye Mk6 axle I reckon
Need to double check the carrier break and the halfshaft spline count.

Re: Diff lock.

Postby Joe in Oz » Thu Dec 08, 2022 11:10 am

This thread is now a bit out-dated. But just to complete the speculation, I have the following to contribute:
My Mk6 (VJ in Australia) has semi-floating rear axles. That means they are located by C clips on the inside of the diff, secured by recesses in the drive gears on both sides. To remove the axles shaft, you have to remove the spider gears, push the drive gears towards the centre of the diff, then remove the C clips.
That location option makes it impossible to fit an LSD or locking diff. Full stop.
Airthies' mention of the Mk7 (VM in Aus) is the only Transit alternative. These rears come with disk brakes, so some messing around with the brake system involved.
I'll look into it a bit more and start a new thread if I find a solution that's repeatable by others. The first hurdle for me is that my diff (115T350) has a 5.125:1 ratio and the VM wasn't available with that option (as far as I can tell thus far). Maybe the (115Hp) engine can cope with 4.xx:1. I'd be interested to hearing form members about that .
Cheers,
Joe
