"...checked gear oil in reservior and it was looking milky"

Was the reservior drained during the work or the hose just pinched off? Drain 2 ounces of oil from the OD drain into a small jar and see if it has water in it.

"he said he couldnt warrenty the work because putting a new lower on an old upper could posiably not seal properly ."

Take it back and find out why the OD has a seal leak by having him perform a pressure test; it could be a defective lower unit seal.

james and if its the lower seal like guy suggested then he almost and should have to replace it for free. if he's the one who sold you the new lower unit
