My front right suspension all of a sudden started squeaking....noticed it on slow speed bumps. The squeak is like closing a rusted door...kinda squeak. Took the wheel off and found nothing. Traced it down to spring area. I can replicate the squeak when I press down on the front right. Does anyone have any idea what to check next? are these control arm bit things dangerous if left for too long? I want to know how long I can go without touching them. I'm easy over the pot holes. Just did a few major repairs costing £300.
