I have a mild knock-knock sort of sound when turning left lately. It isnt a bearing or wheel based sound, I shifted into neutral on flat ground to verify and didnt roll or allow brake use. I also think the steering fluid is on the used up end of things. Smell is clearly of the past due scent. Is there a drain point on the steering to do a refill and see if the sound stops? i havent noticed a loss of power and it seems out to be only one way when turning. Possibly the pitman arm needing change?
Fluid seems ok, was half awake checking it. Though the sound is so slight and few notice unless dead silent since I have a paranoid ear. Its a tick tick but not noticeable unless very attentive. I am gonna lift the car and check the wheel. No sounds otherwise and beside a pitmon arm issue to replace, theres nothing to report. Not sure till i check it out this weekend. Its FWD

Has no rack and pinion gear box. I would suspect the gear box to frame bolts first then a loose caliper to spindle bolt. Make sure when checking that all 4 drive axle boots are intact. A worn dry CV joint will click. To change P/S fluid you must loosen the pressure hose at the gear box and let it drain while adding fresh fluid.
