Review on 🔧 Genuine GM 12639250 Crankshaft Oil Seal Housing, Rear - Premium Quality for Optimum Engine Performance by Rob Parsons

Great product. Updated design. I fixed my rear leak in a 2001 Silverado 5.3 4x4 that had been getting progressively worse over the past 6 years. Bad enough that I stopped making long trips just because I was afraid of losing too much oil. Installation was pretty easy. Pulling out the transfer case and transmission is a lot of work for those of you who want to do it. This can be done in a full day, but will likely take you two days and an assistant. It's been almost a month and still no leaks.
