🔧 Yukon Gear & Axle (YCGGM8.5) Black Cover Gasket for GM 8.2/8.5 Rear Differential - Improved SEO Review

Good product. Fits exactly as it should. No leakage when used with Permatex. Mileage 5000+ without problems. You will need 2 1/2 liters to refill it.

I bought and fitted this gasket about 2 years ago and in that time it has done a good job. This product is recommended if you are looking for a rear differential seal replacement.

Good seal. Do not use RTV. The gasket will do the job if you tighten it to spec. By this point, you've probably watched all sorts of DIY videos on You Tube and don't know whether to use RTV, Padding, or both. Like I said just use a washer and tighten to spec. Note: I tighten the screws a little so they don't loosen over time.

Eaton Trutrack installed. I changed the oil before rebuilding the diff and used the same gasket. Worked well both times. About to use it for the third time to change the oil and check the diff after a recent overhaul. I don't use RTV on my pads. The surface is always clean and dry. never have problems Always tighten the screws in a star pattern to avoid deformation of the housing cover and leakage.
