Hello newbie here I have a 95 yj When I shift into 4h 4l engauges sometimes and other times it won’t . Checked linkage seems fine eliminated front vacuum actuator installed a permanent lock checked fluids . When it engauges it works great when it dosent kinda here a bearing noise and it try’s to engage . It usually will go in when in reverse and forward bunch of times . It’s a 4.0 5 speed . Lifted 8 inches I believe that will be another post . Thanks
