Sierra Rear Differential
Anti Squat Independent Rear Suspension for a Locost / Haynes Roadster is not easy. I have used push rod rear suspension to get a rising spring rate and reduced hub weight
This Haynes Roadster incorporates a Caterham rear differential cover for increased clearance, along with roller bearing, urethane suspension joints.
There are many different Sierra rear drive shafts. Some are much longer than others but some that may be sold as one length may in fact be slightly different.
Fitting inboard shock absorbers and bell cranks to a Haynes Roadster has been a long process, mainly because Sierra Diffs now cost a fortune!
Haynes Roadsters can use some pretty old parts, that will turn up in rather rusty condition. These Granada rear hubs were cleaned up using electrolysis and the results even surprised me!
Like many Locosts or Haynes Roadsters this build will use a Sierra Tripod Differential. Drawing it up in AutoCad has taken quite a few lunch hours!. I did notice that the Lobro and Tripod casing had very subtle changes
Finding a Ford Escort Cosworth 4x4 LSD Diff for this Locost / Haynes Roadster build has taken ages. The prices are rocketing and the choices are getting limited. Luckily, I have mine.

For this Haynes Roadster build I've drawn up Ford Granada 5 stud Axle Flanges in AutoCad. The dimensions will be used to decide upon brake options at a later date.
