Let's be clear-- the sound is not coming from the engine.

It's something more along the lines of suspension, maybe? It's like when the car moves, turning or moving forward, whenever the inertia changes, there's a groaning, as though the body of the car were straining against whatever it were mounted on.

I have no idea. Thoughts? Questions?

  • Does this occur every time, after an overnight park, or just a short stop? – mikes Jun 7 '13 at 17:11
  • Every time the car's inertia changes. During turns, lane changes, stops, starts, increase/decrease in speed. – temporary_user_name Jun 7 '13 at 18:10

My best guess would be worn-out rubber bushings in the suspension components. Check the lower control arms, especially where they attach to the shocks, for cracks or complete deterioration.


When's the last time you greased your suspension ball joints? Unless they're sealed, they should have some zerk fittings on them for a grease gun. If they are sealed, you can drill a hole in them and attach a fitting, but you'd be better off just replacing them.
