YHB K099 Axle Bushing & Seal Kit for Ford 6F35 / GM 6T40 Thin-Wall – Complete Driver Tool for Leak-Free Axle Fitment

The YHB K099 Axle Bushing & Seal Kit (Thin Wall Version) is a complete replacement set and driver tool designed to service axle bushings and seals on Ford 6F35 and GM 6T40/6T45 front-wheel-drive transmissions from 2008–2014.

If you need to repair or refresh the axle bushing and seal assemblies in select Ford, Lincoln, Mercury, Buick, Chevrolet, GMC, Pontiac, Saturn, Holden, Daewoo, Opel/Vauxhall, MG, Saab, or Shanghai Auto models, this kit supplies the thin-wall bushings, seals, and a driver tool to install them correctly. It’s made to match the thin-wall style used in many late-2000s and early-2010s FWD automatic transmissions, helping technicians and experienced DIYers avoid damaging the transmission case or new components during installation.

Which vehicles and transmissions does this kit fit?

This kit is engineered for Ford 6F35 transmissions and GM 6T40/6T45 transmissions in a broad range of models produced roughly between 2007 and 2014. The listing includes specific makes, model years, and common engine displacements to help you confirm compatibility before purchase.

• Ford/Lincoln/Mercury: Edge, Explorer, Fusion, Kuga, Mondeo, Taurus, Transit Connect, MKC, MKX, MKZ, MKT, Zephyr, Mariner, Milan (selected years and engines).
• GM family: Buick, Chevrolet, GMC, Pontiac, Saturn, Holden with 6T40/6T45 transmissions (Cruze, Malibu, Lacrosse, Encore, Equinox, Terrain, etc.).
• Other makes covered: Daewoo, Opel/Vauxhall, MG, Roewe, Saab, Shanghai Auto — check the model/year and transmission code when ordering.

What parts and tools are included and why they matter?

The kit contains the specific thin-wall axle bushings and seals used in these transmissions plus a driver tool sized for safe, controlled installation. Using the correct driver reduces the risk of distorting seals or damaging the transmission bore during press-in.

• Thin-wall axle bushings matched to OEM-style dimensions for proper fit and clearance.
• Seals sized to restore leak control at the axle interface.
• Driver tool that centers and guides the bushing/seal for even seating without hammering directly on the part.
• Instructions or guidance for orientation and torque-related considerations (where applicable).

How will this kit affect a transmission repair job?

Replacing worn axle bushings and seals can stop leaks and eliminate excessive axle play that leads to noise or premature wear. The correct thin-wall parts restore factory clearances and allow the axle to operate smoothly without binding or leaking transmission fluid.

• Stops fluid loss at the axle seal interface.
• Restores correct axle lateral play and alignment in the transmission output shaft area.
• Reduces vibration and noise associated with worn bushings.
• Simplifies installation with a purpose-built driver tool to avoid improper seating.

Are there installation tips or compatibility checks I should follow?

Confirm the transmission code (6F35, 6T40, 6T45) and model year before ordering. Prepare the transmission for bushing/seal replacement by cleaning the bore, inspecting for scoring, and replacing any damaged housings or bearings that would affect fit.

• Verify transmission model and vehicle application against the kit fit list.
• Clean and inspect the housing bore; remove burrs or corrosion before installation.
• Use the included driver tool and a soft, even force—avoid angled or off-center impacts.
• Replace related components (axle, bearings) if wear or damage is present to ensure longevity.

Who is this for: The YHB K099 thin-wall axle bushing & seal kit is intended for professional technicians, transmission specialists, and well-equipped DIYers who perform front-wheel-drive transmission repairs on the listed Ford, GM, and other supported vehicles. If you are restoring fluid-tight axle interfaces and restoring correct axle alignment in a 6F35, 6T40, or 6T45 transmission, this kit supplies the matched bushings, seals, and a driver tool to complete the job safely and accurately.
