How do you know your control arm bushing is worn out?
Alright so I have a 2008 Mustang V6 and there's this squeaky sound coming from my back left tire. It hadnt start making this sound until after I took it on some rough grass/dirt and it was really rough. Ever since then my back left tire occasionally makes this weird irritating squeaky sound I have two assumptions it can either be the shock or control arm bushing? I've already jacked up the car once and sprayed WD-40 on the bushing and that made the squeaking stop for about 3 days then later it came back. I really do not want to take it to the dealership and get charged more than is really needed. What else should I do before I buy a new part? Also could it be that something got caught in the spring somehow? I would greatly appreciate some advice. Thank you
