I started to get a metallic thud. I would not call it a rattle.
But inside the cabin I could tell it was metal related.
Was very apparent in slow speed driving. Any little bumps in the road and I could hear it. I dont really recall hearing it on speed bumps. It was the little bumps in the road- that really made it stand out. At speed-- it was probably there- but too much road noise.
I began to replace parts. I was nearing 150,000. Replacement of the parts would have happened regardless.
Sway bar bushing.
Sway band endlinks
Tie Rod Ends
Front control arm bushings.
Lower control arms (with new ball joints).
Noise was still there....
My struts had 49,000 miles.
I emailed the company because while I was doing all the work- I noticed the jounce bumper had come loose on the strut rod.
I received replacements under the lifetime warranty.
I removed a strut..... and I think I found the source of the sound.
Once driven- the sound was gone.
Turns out the rubber mount that isolates the coil from the metallic base, both moved and was worn through.
So it was metal coil on metal base. Allowing the coil to tap. Metallic thud.....
note the rubber moved down.
Also notice this coil was now metal to metal.. so any small movement of the coil--- resulted in metallic thud/tapping.
You can actually see where the coil was tapping.
You may want to raise vehicle and look at the area and see if youre rubber bushing has shifted.
the coils end-- wore right through the rubber.
