The DC joint on my rear DS is chirping. It just started, and I've only driven about 10 miles since then. Can I drive a bit before fixing, or am I risking further damage? My XJ has a home made BB of about 3" and an SYE with a custom rear DS. I was able to narrow the noise to rear DS by having the rear tires on ice in 2wd, so the front shaft wasn't turning. Winter is good for something.
