I have a 2000 Chevy Silverado Z71, 5.3L, with 120,000 miles. I recently had the differentials serviced and the service shop filled them with synthetic oil, which they claim they drained and put in the proper oils. This was 3 weeks ago, since then I have put roughly 1000 miles on. Today I heard my front end make a clunking and pinging noise, not good. Is there any damage that synthetic oil will do to the differentials? Can I take the front CV shafts off and drive my vehicle back to my town to get it looked at? How much should I expect to pay to have a front differential replaced or rebuilt?
