Recently ever now and again I receive the suspension fault, please stop vehicle in red and picture of the 405 rolling to its demise. I’ve checked the fluids recently and all is full. No leaking that I saw on the front ARB and no leaking on rear. Didn’t tear the skid plate off to check the block but nothing looked wet in that area. From what I have researched it says lines are commonly rusted out and so far mine are ok. Would this lead me to believe that the valve block is on its way out?
