Restoring the Lotus Esprit S1 Rear Hub Carriers, Replacing the Rear Wheel Bearings

Replacing the rear wheel bearings on an S1 Esprit is easy as long as you have a press. I removed the entire hub carrier assemblies from the car (including stub axle, half shaft and u-joints) and took them to a shop to have the stub axles pressed out of the bearings (no, they won’t come out any other way). After the stub axles were out, I had the bearings pressed out too.

I had the hub carriers walnut blasted to restore their original appearance, and ordered a set of bearings and new grease seals.

Since the bearings didn’t slide back into the hub carriers, I froze them overnight and heated the carriers to 300F in my kitchen oven and then the bearings simply fell in without effort. After replacing the c-clip to anchor them in, the job was done!

New seals and c-clips, ready to install.

Job done!
