Inspect hose and connections and bearing seal.

The fall is not so noticeable, but I can see dripping and spots on my driveway.

I tried to inspect the hoses, but it’s very difficult for me to tell if they are leaking.

I tried to take a better picture:



there’s fluid where all the arrows are.

Use a brake cleaner to dowse the suspect area and wipe dry if needed. Let the vehicle sit for 5-6 hours to see if there is seepage. This will identify location od leak under gravity and no pressure.

Then start the vehicle and without moving see if you can spot the leak within 5-10 min of idle. Under pressure the fluid can be sprayed to an adjacent area so you have to keep that in mind.

next would be without moving, just turn the steering wheel 1/2 a turn to produce pressure on line.

If you cant spot a leak then the next check would be driving and stopping to check for leaks. The problem with this approach is that the fluid is displaced by the air flow.

If the fluid is fresh [clear] it is hard to spot a slow leak. You can blow talc around the suspect area to make the leak more visible.
