   263XHD Transfer Case Pump Upgrade Combo, May 26, 2019  By Leon Crouch (Phoenix, OR)(Verified)
This kit is one of the best aftermarket kits I've ever bought! After watching the video, the oil pump and transfer case housing install was super easy. All of the components appear to be high quality and everything fits as it should. Much better than trying to scab together all the parts from multiple vendors!

Pros: came with everything I needed. Made for a very smooth installation
Cons: the snap ring pliers did not spread the snal ring far enough. Plus, they broke. Had to go buy my own snap ring pliers.

The kit came with everything that I needed minus a new clamp for the front drive shaft boot. The repair itself only took about 45 minutes and was very easy to do.

Shipped fast. I was a little disappointed with the size of the snap ring pliers. They didn’t open up far enough. I wish they had some directions to help with the install. Instead, I watched quite a few YouTube videos.

This kit came with everything in perfect order except the snap ring pliers. Not only were they not wide enough to remove the snap ring to separate the case half, they broke and I had to stop and go to the store to buy another pair of snap ring pliers. For that, this product gets 4 stars. Everything else in the kits was on-point.

The kit completes with all the important parts to repair transfercase rub issue. I would recommend that you also get a front driveshaft boot kit as the kit does not come with the straps to reinstall the boot. The snap ring pliers that come in the kit do not open far enough to effectively get the snap ring back on during the reassembly process. Other than that this is a good kit.

Originally threw a rear U joint which damaged the rear of the transfer case. After poking around the interweb I found this kit. It was a little more expensive but the reviews were good. Installed the kit, couldn't be happier. Everything I needed was in the kit and was of high quality. Good job Merchant!
