Description

The original 15mm head transfer case bolts are prone to corrosion and rust especially in northern climates caused by dissimilar metals being used. Corrosion resulting from this can cause the factory coating on the bolts to delaminate making it very difficult to get a wrench or socket onto the bolt head. To improve the appearance and longevity of your transfer case we put together this bolt kit which uses high quality bolts and aluminum washers with a 15mm hex head to replace the original bolts when you are reassembling a 246, 261HD, 261XHD, 263HD or 263XHD transfer case. This combination of aluminum washers and high quality bolts with the Merchant Automotive kit helps to prevent corrosion ensuring that the bolts will be serviceable for many years to come. One kit includes the bolts, stud/bolt and washers to completely replace the worn or damaged bolts on a single transfer case. Be sure to note the accessory bracket locations prior to disassembly for proper positioning during reassembly.


KIT INCLUDES: 

  • Aluminum Washers (qty. 17)
  • 15mm Replacement Bolts (qty. 16)
  • Replacement Stud/Bolt (qty. 1)

FAQ:

I hear a grinding noise at low speed after reassembling my transfer case. What could that be?

A low speed grinding noise is most commonly caused by the rear output bearing snap ring not being fully seated causing the bearing to move out of proper alignment. Verify that the snap ring is fully engaged and properly seated in the rear housing and the locating groove in the bearing.

What would cause a speed sensor correlation code after installing this upgrade?
A speed sensor correlation code is often accompanied by a low speed grinding noise and is frequently caused by the rear output bearing snap ring not being fully seated causing the bearing to move out of proper alignment. Verify that the snap ring it fully engaged and properly seated in the rear housing and the locating groove in the bearing.
