I recently bough a GX470, and it has 185,000 miles. I am experiencing a relatively loud squeaking noise coming from the front driver wheel well, and it is pretty bad. Like breaking people's necks bad. I have been to 2 different places, and they both mentioned upper ball joints. I have replaced both the upper ball joints, and the whole lower control arms (since the ball joints are known to fail with age), and it hasn't stopped. The first place that I went suggested that it was likely worn body mounts, and considering the age and mileage of the vehicle, it seems like that would be something that would need to be done anyways. I am just wondering if anyone has experience with anything like this, and I would be greatful for any suggestions. I will try to get a video of the sound and post it under this.
