★ Top Answer
The primary reason why your Jeep Wrangler's front differential might start leaking is due to worn-out seals. If the seals are old, there could be built-up sludge that has been preserving the fluid until they start to deteriorate. While some suggest that flexing causes the leaks, it's typically not the main issue as long as the seals are intact. It's crucial to monitor your differential fluid levels closely, especially if you suspect a leak. It's a good idea to replace all the seals (front and rear) simultaneously because if one is showing signs of wear, the others are likely to follow suit soon, assuming they are of similar age.

Leaks from the front and rear differential pinion seals as well as the transfer case are common issues in Jeep Wranglers. Transfer case leaks often occur at the contact points on the case and involve resealing the transfer case connection.
