Sierra Cosworth Differential

This isn’t just an Sierra Cosworth Differential, it’s the missing dimensions I need to finish the suspension analysis in rFactor and Kangaloosh. I was missing the measurement between to the two 100mm drive shaft bolt flanges. Now I have everything, it’s all systems GO!

My advice : –

If you see a Sierra Cosworth Differential at a good price BUY IT NOW!

– the price is rocketing and they are getting scarce. If I had bought ones I thought were ridiculously expensive 6 months ago, I could have saved £50!

rFactor and Kangaloosh are excellent pieces of software used by the gaming community to simulate cars as accurately as possible in computer driving simulation games. You may ask why I’m using this ‘toy’ software to design a real car but top race teams use these simulation games to trial different suspension set-ups on various tracks before ‘going live’ with the real thing. If you can think of something on a car to simulate, they simulate it; even the colour and amount of smoke upon each gear change.

Back to the Escort Diff….

After 6 months of trawling the auction sites, I’ve finally got the 4×4, 3.62:1 ratio diff I needed to match the front one. The diff is a low mileage (72k miles) 7″ 1995 Escort Cosworth (never raced or rallied). It’s even the LSD model.

It will be fully stripped and rebuilt with new bearing and seals.

Once rebuilt, with the casing acid etched, a new rear cover and a new set of bolts, it should be as good as new.

Sierra 100mm Stub Axle

There is a choice of two sizes for the Ford Sierra Rear Stub Axle : 100mm 108mm For this project I've chosen (read bought) 100mm rear stub Axles (27 spline). Again, I've been lucky and got a pair of brand new Ford Sierra Cosworth Group N stub axles. Another

Sierra Rear Shafts

How do they measure Sierra Rear Shafts? There are obviously different length versions made, but even ones that appear the same length have subtle differences. Take these two shafts, at first glance they appear very similar. But one uses an both inner and outer split rings(bottom)and the other

Rear Suspension

The rear suspension is now taking shape. I was beginning to think that I would never find a Sierra Diff! Nearly a year of surfing and hundreds of bids later, I have a gem of a diff. When I opened it up, there was zero signs of wear and the

Sierra Tripod Differential

The Sierra Diff was quite hard to measure and draw up. I started with the push in shaft 7" 'Tripod' version. Most of the time drawing up this Ford Sierra Differential was taken during the measurement stages. When there are so many dimensions to be taken you almost need a

Granada Axle Flange

It seems like an endless game, drawing up all these components, but the 5 Stud Granada Rear Axle flange has now been drawn up. These are the 27 spline, 5 x 112mm axle flanges from a 1986 - 1994 Ford Granada / Scorpio. Other vehicles to share the 5 x 112mm stud

Rear Wheels

With the change in profile of the rear bodywork, the rear wheel arch can either be moved upwards or increased in diameter. This is the standard rear wheels and arch arrangement (16in wheel) before the rear bodywork re-profile. From an aesthetic viewpoint the 16 inch diameter wheel is about

Rear Cantilever Pushrod Suspension

With the rear pushrod suspension, initially the decision was made to use Sierra 4x4, for which I found that many websites claim the the rear track width to be 1468mm. I’m not sure where this comes from as it is actually 1550mm hub to hub. Initially, I chose Cosworth

Caterham Rear Diff Cover

I've replaced the rear suspension mounts with roller bearings, but in the the process discovered that there was no way to remove the differential. The rear chassis is different to the standard Haynes Roadster as it has much more triangulation. This makes the access to the differential very tight.
