It wasn't showing any pump rub leaks but I wanted to get this upgrade before it happened. After youtubing the process, I bought this kit and took it to my mechanic. He said it went right in, came with everything he needed and had no issues. Took about three hours according to him to pull the driveshafts, drop the transfer case, put in the new upgrade and reinstall everything. Seems to be running fine inside the transfer case and now no worries about the dreaded pump rub hole. ### ⭐⭐⭐⭐⭐ Transfer Case saver! *by A***Y on Reviewed in the United States on August 25, 2019* After getting it rebuild and having the same issue a year later I went to YouTube for a real fix I came across this. This went in transfer case #3 for me and believe it will be the last.So many places say that rebuilt will take car of it or they use a thicker case bs. They just say that to reassure you because it should last 150k. Would have been nice but 17k later another leaking case, if they would have put this in I would still be on case 1. Glad I have it now! ### ⭐⭐⭐⭐⭐ great quality *by C***R on Reviewed in the United States on February 20, 2019* I did not have as much pump rub as some did. I pulled my NP246 from my 07 Suburban to see if there was an issue because I was (and still am) getting the famous GM clunk. I was hoping there was something in the transfer case that was worn out after 185k. No such luck. While I was in it though I decided to fix a TSB problem with these transfer cases. I replaced the pump housing and slipped it back in. Great quality product and fit perfectly. You either need one or you don't. If you are having symptoms of pump rub (leaking fluid), buy this to correct any future problems after you fix your case housing :) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/5738251-10001-transfer-case-pump-upgrade-kit](https://www.desertcart.tw/products/5738251-10001-transfer-case-pump-upgrade-kit) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-23*
