I have a 2000 automatic Legacy with new CV axels. When shifting into REVERSE first thing in the morning, there is a metallic "clunck" in front Left area. Usually I get the idle down to about 1000 before shifting. and it still clunks. Doesn't do it at all the rest of the day. Only time is 1st thing in the morning. Car is in garage, protected from freeze.
Ideas???
