The manual shaft in Mitsubishi/Isuzu AS68RC (A465) units commonly breaks off at the threaded section during removal of the jam nuts, which secure the manual lever to the shaft. This is caused by corrosion, and the relatively weak steel of the OE design exacerbates the problem. Sonnax manual shaft kit 99740-08K is a direct replacement for broken shafts in Mitsubishi and Isuzu AS68RC units. The Sonnax shaft features superior-strength steel and has a rust-preventative coating applied to minimize future corrosion.
