Re: no rear difflock

Hi Did you check the travel of the difflock ram ...any air in the system and the stroke is shortened... try putting all back and bleeding the system..if fluid is of unknown age and quality remove all and replenish with Dot 4 hydraulic oil then bleed by having someone pull and push each lever until clear fluid flows rgds
