Brooks, > Is there a way that I can keep my (rear) diff lock at speeds faster than >20mph (or whatever)? I would think twice about locking the rear diff at speed. It may cause the back end to spin out more easily on slippery roads (recalling from my days in Montreal). Richard Funnell, OES raf40@oes.amdahl.com tel. (408) 992-2265 fax. (408) 746-7633
