The past 3 weeks I've heard a sqeaking sound from the left front of my 2000 XLT, 3.0 when I hit bumps. It's gotten louder & is almost constant now. If I slowly push down on the left front fenderwell it sounds like an old creaking door. If I bounce it up & down it sounds like a donkey. Anyway, I got under it & sprayed grease on every friction point I could find. No difference. Could it just be a dried up, worn out shock? Or did I miss some place with the grease? It's got about 84,300 miles, original shocks.
