Hello I am new here and I just got a 2000 ford f150 xlt 4x4. The driver side leaf springs are squeaking really bad. It squeaks when driving and also when I just lift up on the fender. It squeaks with just about anything really. I have sprayed white lithium grease all over the leaf pack and bushing and I also jacked the frame up and sprayed it in between the leaf springs and it did not help. Its making me really frustrated so hopefully you guys can help me figure it out. Thanks.
