One weekend project that I find enjoyable is to troubleshoot and fix and maintain cars and trucks. On this Ford F-150 I replaced suspension components that had worn out, replaced the wheel bearings and brake rotors and replaced the spark plugs and ignition coils. After all this work the truck was riding smooth and the engine was consistent through the whole spectrum of RPMS.
My upcoming project is this blue and white 1986 ford ranger. It will need some transmission and starter work along with suspension, body and interior work to make it a comfortable ride.
