Hello, I just finished building my copy of the Lego Land Rover, and it makes a cracking noise when in reverse/ hi or low/ gear 3,4. I know a lot of people are having the same issue as I am. I have searched throughout the web for an answer, but couldn't find a clear one. Some of the answers didn't work for me too. I found this one answer on Eurobricks from Twoofive: "I solved the issue by changing the 8/24 gearing to the diffs into 16/16 , works a lot better now." I don't exactly understand this answer by Twoofive. Can someone please explain this answer to me? Also if possible, please show me pictures of what it would look like after applying the answer from Twoofive. If the answer from Twoofive works to fix the problem, all credit goes to Twoofive. Thank you!
