The patented Cognito Alpha Ball Joint is the next level, end-all be-all solution of upper ball joints. It eliminates the problematic dust/grease boot by using a durable scraper type seal that is not susceptible to damage that a traditional dust/grease boot is. Although the ball joint is firmly sealed and pre-greased, there is a grease fitting at top for any periodic maintenance needed. With a small internal cavity for grease, the joint does not need much at all. The internals are alloy steel, absent of any plastic liner, with alloy races and grease paths. The carburized and surface coated taper pin is a precise fit, has an oversized sphere in the socket for large contact surface providing excellent strength and wear characteristics.
Maintenance free ball joints therefore seem like a great solution, unfortunately there are factors that can cause issues. If a dust/grease boot is compromised on a maintenance free joint allowing contamination inside, grease can't be pumped in from the top to flush out contaminants and re-lubricate the joint. The plastic liner of the joint then wears and creates a squeaky joint that needs replaced. Replacing a traditional press in ball joint takes time and can be a pain in the rear without the proper specialty tools.
While ball joints are a wear item, that wear is accelerated by larger tires, high cornering loads, damaged dust/grease boots, and a lack of lubrication. It is well known that most lube shops are not tending to greaseable joints during maintenance, therefore a lack of lubrication causing prematurely worn ball joints has been an issue for the last decade or more.
