NTY Transfer Case Output Shaft Repair Sleeve | BMW xDrive Transfer Case Fix For BMW X5 E70 E53, X6 E71/ E72, X3 E83, 3 Series E90

Fix transfer case fluid leaks at the root cause with the NTY Transmission Output Shaft / Transfer Case Repair Sleeve.

Over time, the spinning motion of the output shaft cuts a microscopic groove into the metal surface where the oil seal sits. Simply replacing the rubber oil seal won't fix the leak because fluid will still bypass through that worn groove. This premium aftermarket repair sleeve presses directly over the worn shaft, providing a perfectly smooth, flawless new surface for the seal to ride against—saving you from having to purchase an incredibly expensive replacement output shaft or complete transfer case assembly.

Key Features & Benefits

• Cost-Effective Rescue: Eliminates the need to strip down and replace expensive internal transfer case hardware or output shafts.

• Engineered Precision: Manufactured by NTY to strict European quality standards, ensuring a precise interference fit over the factory shaft.

• Restores Seal Integrity: Restores a flawless, friction-optimized running surface to completely stop oil migration out of the transfer case.

• Premium Durability: Constructed from hardened, wear-resistant steel alloy to resist future grooving and scoring under heavy xDrive load distribution.
