Just had my JK re-geared. Auto shop recommended to comply with specific break-in procedures and to come back after 500 miles to change out the oil with the front and rear diff's. For convenience I'd much rather use my local automotive shop to change out the differential oil. Is this OK or does the re-gear need inspection ie. (Wear marks)? In that case I would bring it back to the mechanic who installed the gears.
