Can anybody give me some advice as to what might be causing an irritating squeeking noise coming from the rear of my LX? It's only noticable when driving over uneven pavement or rough roads.I had new OEM shocks installed all round a couple of months ago , but didn't get rid of noise. I've checked underneath and all seems to be tight. Could it perhaps happen to be my springs? They are original ( truck has 121,000 miles). There is also a bit of a clunk or thud when I hit a bump coming from driver side rear wheel. Had new discs and bearings done 5 months ago on rear as well. Thanks for any advice! - Tim
