The 1905 Riley 9HP has had its rear differential and suspension pulled off the chassis to be moved to the workbench for the Bridge Classic Cars workshop to rebuild/refresh.

After testing last week, the team pulled the pieces from the chassis to pull apart and rebuild. The rear differential has had new ball bearings and races put in and everything cleaned up and regreased. The rear swing arms were also pulled out to be inspected and the mounting holes redrilled and cleaned for the new shackle bolts to slip through with no binding.

Finally, the team have been working on the spark plugs for the car and inspecting the correct gaps and spacing on the new adapter.
