Dorman 697 706 GM Differential Cover: Ultimate Protection for Your Vehicle's Gears Review

This is a great rear diff cover. I didn't like that there was a drain plug. But for the price. It's impossible to win. I've noticed that a lot of people complain about the drain plug leaking. So I definitely understand why it happened. I didn't have the drain plug on. It wasn't much. But not tight enough to prevent leakage. Therefore, before installing, tighten the drain plug as much as possible. Otherwise it's a good case that I'm sure will last a very long time.

This cap fits my 2004 Chevy Tahoe 5.3L perfectly. It didn't come with a gasket, but I ordered the Fel-Pro anyway. Other than that, the only issue I've encountered, like others, is the drain plug. I pressed it firmly before installing, but then it still leaks. I removed the cork, wrapped teflon tape around it, tightened and now there is minimal dripping but it stays. While I haven't lost a ton of gear oil, it still annoys me that I have trust issues with the filler plug. If it gets annoying…

I bought this rear diff cover from Dorman for my 2004 Chevrolet Avalanche 1500. It came with a better gasket than I expected so I ended up using another gasket that I bought separately. I cleaned the lid very well, applied four coats of Rustoleum Professional black enamel spray paint over the weekend, then applied it with 12-point ARP -Stainless steel bolts and filled the differential with over 2 liters of AC Delco 75w-90 fully synthetic gear/bridge oil.Looks really good and the Eaton G-80…

Perfect match for my 2006 GMC Sierra rear diff. Instead of RTV or Form-a-Gasket I prefer to use a pad bought from Revain. The drain plug (nice feature with a magnet on the end of the bolt) with a threaded hole had a large burr inside that I have to file off to eliminate the risk of loose burrs falling off and getting caught in the gears. This part is thick. I replaced my original cover as it was so badly rusted that the transmission oil leaked out. There were similar problems with corrosion of…

I bought this for my 2000 GMC Yukon Denali as the previous diff cover was rusted and leaking. I ordered this, a Felpro gasket (Fel-Pro Rear Axle Case Gasket RDS55028-1) and 4 liters of differential oil (Mobil 1 104361 75W-90 Synthetic Gear Lube - 1 quart (2 pack)). I ended up using just over 2 liters of diff fluid, but it's always nice to have more. I used RTV (JB Weld 31314 High Temperature RTV Silicone Sealant & Sealant – Red – 3 oz)) to seal the gasket and Loctite (Loctite Heavy Duty…

Took 5-6 days for delivery which is too long for Prime Delivery. When the part finally arrived, the differential cover mating surfaces (where it connects to the differential case) had a damaged surface with dents and scratches. This is the most important and functional surface of the differential cover and should be mirror smooth. To mention scratches on this surface means it may not fit snugly in the case and will result in differential fluid leakage. The magnetic drain plug insert on this…
