Symptoms
Old, dark fluid, a truck that's slow to level, or a lift via the height-sensor links that has left the reservoir low.
The fix, step by step
- Park on level ground with the suspension in N, engine off.
- Suck the reservoir empty and refill with fresh AHC fluid.
- Bleed one corner at a time (front driver, front passenger, rear driver, rear passenger): open the bleeder until that corner bottoms out, close it, start the engine and let the truck re-level, then switch off.
- Repeat until clean fluid comes out of each bleeder, and never let the reservoir run low.
