Re: Rear differential intermittent "clunk" (metal on metal)
Odd. If there are any broken parts, it would be obvious while doing a thorough inspection. It may be coming from the limited slip. Was the oil in the diff changed recently? (before the noise started?)
Some lockers don't like limited slip additive. And believe it or not, it's hard to find gear oil that doesn't have it added already. My Detroit was acting up last year, and once I changed the fluid it was fine. I had to search for some oil that didn't have any LSD additive.
