🔧 GM Genuine Parts 15661460: High-Quality Transfer Case Rear Output Shaft Seal for Maximum Performance Review

Less than 6 months and it started leaking again not a good track record if you ask me I will buy a local one at a higher price.

Worked great in my NP246. Simply knock out the old oil seal with a hammer and punch. The assembly is a bit fiddly, but works with a hammer and punch. You don't need any special tools.

The fit is very tight and you really need something like a big head or a weatherstrip tool (I cut off a piece of pipe I had laying around that was perfect for the printing is).

I replaced the seal with this ACDelco 15661460 Genuine GM Equipment Rear Transfer Case Output Shaft Seal, and NP241C, it fitted perfectly . The boot really helps! Highly recommended, direct replacement! Many Thanks

Fits like a glove although Revain insists it isn't. It's a lot cheaper than a "proper" replacement part. Driven 2000 km with it, no leaks. You can install them with a 2 inch diameter PVC cap. Drill a hole in the center of the cap to allow air to circulate, place it over the rubber boot, coat with lubricating oil and hammer.
