Tech Forum / Re: Peerless differential - through chassis fixing
« Last post by RhysN on 09 Dec 25, 10:10 am »Hi Steve. having been around these things for a long time I can say that the focus has changed. Way back when, folks were attracted by the simplicity, over the years they have become more complex (heavier) and have gained a different aspect. The original Stevenson had one wheel drive, as do the majority of the ones I have driven both in the US and NZ for example. Those original were through the frame tube, it wore out a hole saw achieving that.
Where the rear axle goes, either through the frame, over or under is usually dictated by the front axle curvature and spring set so that the chassis rail is more or less level. Some cars are built low, some not so and in the case of my Napier for example, it's following 2 things. 1, what does the inspiration car look like, and 2 I am using the US guidelines which mandate the seat height above the axle. As a result it's high.
It's entirely your call. For me, my first car was through the rail, subsequently they have varied.
