Suspension Noise at 100k, What to Look For?

[san rensho]

The creaking noise is typically caused by the lower control arm, coffin arm. The easy fix is to make a very small hole in the lower control arm ball joint rubber cover. Then inject either WD-40, grease or silicone into their, depending on your choice. The Fixx can last for a week or months, but it's not permanent. And by the way, the creek does not mean that the ball joint is bad period

But I agree with the sentiments of those above, you should shake down the entire suspension once you have it up in the air.
