Deluxe Bearing and Seal Kit, 263HD Transfer Case | 2001-2007

Deluxe Bearing and Seal Kit, 263HD Transfer Case | 2001-2007

The Merchant Automotive Deluxe Bearing and Seal Kit includes the bearings, seals, thrust washers and wear parts needed to overhaul the 263HD transfer case used in 2001-2007 gas Chevrolet Silverado and GMC Sierra HD trucks. Instead of tracking down a dozen individual parts, you get every bearing and seal for the rebuild in one kit, including the range shift fork pads and both pickup tube seals.

Key Features

• Complete bearing and seal overhaul kit for the 263HD
• Front input, front output and rear output seals
• Input gear (32 spline), front output, input/front output and rear output shaft bearings
• Range shift fork pads (pair) and planetary thrust washers
• Mainshaft O-ring, speed sensor seal and pickup tube seals
• Transfer case to transmission adapter gasket

Benefits

Once a 263HD is apart, every bearing and seal should be replaced. A worn bearing left in place brings back the noise, and a reused seal brings back the leak. Worn range fork pads let the fork contact the shift collar, so replacing them during the overhaul helps prevent grinding and pop-out. Replace if worn or damaged. Commonly replaced at the same time: Merchant Automotive Transfer Case Pump Upgrade Kit | 1998-2007, Transfer Case Snap Ring Kit - 263HD | 2001 - 2007.
