Description
Product Overview
The UNIONTEK bearing kit is a precision‑engineered solution designed specifically for 2005‑2015 Toyota Tacoma pickups, covering both 2WD and 4WD configurations. Each component is manufactured from high‑strength steel alloys that have been heat‑treated to achieve superior wear resistance, ensuring long‑term durability even under demanding driving conditions. The kit includes a centrally located bearing that supports the transmission input shaft, three greaseable universal joints that accommodate angular movement while maintaining a sealed lubrication environment, and three sets of snap rings that secure the assemblies in place. All parts conform to the original equipment specifications, replacing part numbers such as 372300K040 and 5‑1203X, and they are dimensionally matched to the vehicle’s factory tolerances. The design incorporates a low‑friction surface finish on the bearing raceways, reducing heat buildup and extending service intervals. Greaseable joints feature sealed ports that allow periodic replenishment of high‑performance synthetic grease, preventing contamination and preserving smooth operation. The kit’s compact packaging—one center bearing, three universal joints, and three snap ring sets—facilitates straightforward handling and storage, while the included installation guide provides step‑by‑step instructions to minimize downtime. By addressing common wear points in the drivetrain, this kit helps eliminate the vibration, noise, and shifting harshness that drivers often experience as the original components age.

Usage
This bearing kit is ideal for owners who demand reliable performance from their Tacoma during daily commuting, weekend off‑road adventures, and heavy‑load hauling. Whether navigating city streets, tackling rugged trails, or towing trailers, the reinforced center bearing and greaseable universal joints maintain consistent torque transfer, reducing the risk of drivetrain failure. The kit is also suitable for professional mechanics performing routine maintenance or for DIY enthusiasts who prefer to handle their own repairs. Installation typically requires removal of the transmission cover, extraction of the worn bearing and joints, and replacement with the new components using standard hand tools. Because the universal joints are greaseable, users can schedule periodic maintenance to replenish lubrication, extending the life of the entire assembly. The kit’s compatibility with both 2WD and 4WD models means it can be used across a wide range of Tacoma trims, from the base SR to the off‑road‑focused TRD Pro. Drivers who experience shuddering during gear changes, excessive noise from the transfer case, or premature wear on the original bearing will find this kit restores the smooth, quiet operation that the vehicle was designed to deliver.

FAQ
What vehicles are compatible with this bearing kit?
The kit is engineered for 2005‑2015 Toyota Tacoma models, covering both 2‑wheel‑drive and 4‑wheel‑drive configurations. It replaces part numbers 372300K040 and 5‑1203X, making it a direct fit for the factory‑specified bearing and universal joint locations.
Do I need special tools to install the kit?
Installation requires standard hand tools such as a socket set, torque wrench, and a bearing puller. No specialized equipment is necessary, and the included installation guide provides detailed steps to help you complete the replacement safely and efficiently.
How often should the greaseable universal joints be serviced?
We recommend inspecting the universal joints at each major service interval—typically every 12,000 to 15,000 miles—and re‑greasing them as needed. Using a high‑performance synthetic grease will maintain optimal lubrication and protect against contaminants.
What warranty does UNIONTEK offer on this kit?
UNIONTEK provides a limited warranty that covers manufacturing defects for one year from the date of purchase. The warranty does not cover damage caused by improper installation or external factors such as accidents.
Can I install the kit myself, or should I seek professional help?
If you have basic mechanical experience and access to the required tools, the kit can be installed as a DIY project. However, if you are uncertain about any step, we recommend consulting a qualified automotive technician to ensure proper fitment and performance.
