K80107 Front Lower Ball Joint Kit

For owners maintaining a Ford Escape, Mazda Tribute, or Mercury Mariner from the listed model years, this two-piece front lower ball joint kit is intended as a replacement option for the lower front suspension joints. Its metal-to-metal design is described as allowing grease to move across the bearing surface, which is meant to reduce friction. The listing covers several years and three related vehicle lines, but it does not give trim-level fitment details or installation instructions. Check the application for your exact vehicle before ordering, especially if you are replacing only one side.

Size & fit

The stated fitment is Ford Escape models from 2001–2012, Mazda Tribute models from 2001–2011, and Mercury Mariner models from 2005–2011. The package contains two K80107 front lower ball joints. Those ranges help narrow the search, but they are not a substitute for confirming the part number against your vehicle, no trim, engine, or other fitment distinctions are provided here.

This is a suspension replacement part, not a general-purpose lubricant or a repair kit with other components listed. If you are diagnosing a front-end issue, first establish that the lower ball joints are the parts that need replacement. A concrete use case would be installing the pair during a front suspension repair on one of the listed vehicles, rather than buying a single joint when both are needed. Does the two-piece format match the repair you have planned? That is worth settling before choosing a kit.

Pros

• Two front lower ball joints are included, so the package is set up for a pair replacement.
• The metal-to-metal bearing design is stated to let grease flow over the contact surface and help reduce friction.
• The description says fresh lubricant can flush contaminants, with the aim of limiting corrosion and wear.
• The specified vehicle list gives clear model-year ranges for three vehicle lines.

One practical limitation: the available details do not identify included installation hardware or provide fitting instructions. The listing also describes the joints as easy to install and says their tolerances support installation and steering alignment, but that does not establish how straightforward the job will be on a particular vehicle. Installation depends on the repair and the vehicle’s condition.

Buying verdict

Worth considering if you need a pair of front lower ball joints for a vehicle in the stated application ranges and want a kit whose description calls out grease flow across the bearing surface. Compared with buying a single replacement, the two-piece package makes more sense when your repair calls for both joints, if only one is needed, the second may not be useful for the job at hand. It may not suit you if your vehicle’s exact application is uncertain or you need a kit with clearly listed hardware and detailed installation guidance. The fitment list and K80107 identifier are the strongest checks to make before deciding.
