OE-Quality CV Boot Kit for Driveline Repair

GKN Loebro 306588 is an OE-quality TPE CV joint boot kit built for precise driveline service. It is designed for applications where the original axle uses a thermoplastic elastomer boot, helping protect the joint from contamination, heat, and premature wear.

For Volkswagen Jetta, Audi TT Quattro, Audi TTS Quattro, and related front axle applications, the correct boot fit is critical. GKN Automotive supplies this boot kit to match the joint design and material requirements used on modern drivetrains.

Key Features

OE-quality TPE boot kit for CV joint service
Thermoplastic elastomer construction rated for high operating temperatures up to 240°F
Solid black boot design
Exact-fit replacement for applications originally equipped with a TPE boot
GKN Loebro part number 306588
Cross-reference: 5N0498203

Detailed Product Overview

This CV joint boot kit is engineered for front axle and outer joint applications where the factory design calls for a TPE boot. The boot material matters because modern drivetrains generate significant heat and torque, and the wrong replacement boot can lead to early failure. GKN Loebro 306588 is intended to restore the protective seal around the joint while maintaining the fit and material characteristics expected in OE service.

Compatible vehicle coverage includes 2013-2016 Volkswagen Beetle, front left outer and front right outer; 2017-2020 Audi A3, front left outer; 2018-2020 Audi S3, front left outer and front right outer; 2019-2021 Audi TT Quattro and Audi TTS Quattro, front left outer and front right outer; and 2022-2025 Volkswagen Jetta, front. It also applies to select Audi A3 Quattro, Volkswagen Arteon, Volkswagen GTI, Volkswagen Golf R, and Audi Q3 front axle positions listed in the fitment data. Part number 306588 is also referenced for select Volkswagen and Audi driveline service applications.

What It Helps Address

Torn CV boots that expose the joint to dirt and moisture
Slipped boots that no longer seal correctly
Porous or heat-damaged boots on high-torque drivetrains
Grease loss from a compromised outer or inner CV joint seal
Noise and wear caused by contamination entering the joint

Installation Notes and Tips

Verify the original boot material before ordering; if the factory driveshaft uses a TPE boot, select the matching TPE replacement. Confirm joint end and shaft end dimensions, rib count, and axle position before installation. This kit is listed for front, front left outer, front right outer, front outer, and front left inner positions depending on the vehicle application. Professional installation is recommended to ensure the boot seats correctly and the joint remains properly protected.

Quality Assurance

GKN Automotive is a global driveline manufacturer with OE-level engineering standards, and this boot kit is produced to match the fit and material requirements used in original equipment service.

This part fits 62 vehicles
