Sierra 4×4 Front Driveshaft Cover

This Sierra 4×4 Front Driveshaft Cover forms part of the Cosworth front axle assembly normally bolts to the nearside of the sump.

In this design however, it will be mounted to a custom axle assembly.

The cover would normally bolt to the right hand side of the sump / shaft assembly in the picture below.

Sierra 3.9:1 Front Differential

It's been a few weeks since my last blog and for good reason. My project has a new home. I had to knock down walls and do some pretty scary electrics, but the work is coming to an end. The next job is a heavy duty chassis table. More

Modified Front Sierra Differential

Unlike the Rear Sierra Differential, the front differential is not located along the vehicles' centre-line. The prop-shaft driving the front diff exits the side of the MT75 gearbox and travels forward to the front differential bolted to the side of the sump. The front differential mounts only to

Ford Sierra Front Stub Axle

I'm getting better at the CAD stuff. The latest item to get drawn up is the Sierra Group N front stub axles. When I started learning AutoCad this would have taken me days if not weeks to draw. These took about under an hour to measure up and

Kit Car 4x4

I now have all the pieces cut ready to take to the specialist TIG welding company. It'll look much better once all the sticky tape is removed! There was a stage when I was worried that the assembly would be a little weak, yet this mock-up is roughly

Sierra Front Differential Part II

Sorry, but there is not much to show again this week. I ran out of welding wire and the reel I ordered on Fleabay still hasn't arrived. The same applies to the aluminium plate, aluminium tubes, gasket set and bolts. I'm rubbish at excuses when it cold........... What

Granada 4x4

The Ford Granada 4x4 is a rare sight these days and finding some front hubs wasn't easy. Why did I chose the 5x112mm stud pattern Ford Granada 4x4 over the 4x108mm stud Ford Sierra Xr4x4 or Cosworth? Wheels and brakes are the answer. The Granada shares the same stud

Suspension Mounts

I've done the mounts for the front suspension A-arms and the Sierra Front 4x4 mounts. I'm not the first to mount a 4x4 front diff into a Haynes Roadster and at the speed I work at it's not surprised. It's not just a case of

Ford Sierra Front Differential Cover

This project will use a Ford Sierra Front Differential 4x4, 3.92:1 front differential (from a non-Cosworth Sierra 2.0s 4x4). Normally this diff would bolt to the alloy sump with integral drive shaft. However, for this application the diff will be mounted in front of the engine,
