How to find the right Automotive Replacement Constant Velocity Inner Tulip & Housings AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Automotive Replacement Constant Velocity Inner Tulip & Housings
- Joint type and geometry
- Match the tripod tulip to the spider: the same number of roller tracks and a compatible roller diameter. Match the housing's stub-shaft spline count and seal surface to the transmission. Mismatched roller diameter causes play and clunk, and a wrong stub spline or seal diameter will not fit the transmission.
- Boot interface
- Confirm that your existing or new inner boot fits the outer profile of the replacement housing. Tripod housings are often lobed, and a boot designed for another profile will leak.
- When it makes sense
- Buy a tulip or housing alone only when the spider and rollers are reusable or replaced at the same time. Otherwise a complete inner joint kit or axle is simpler. Worn rollers in a new tulip, or a new spider in a worn tulip, wear quickly and still clunk.
Brands that matter
- GKN (Löbro / Spidan): Inner joint and tulip components for many OE applications.
- Empi: Inner CV parts for air-cooled VW and similar classic applications.
What to avoid
- Mixing an old spider with a new tulip without checking roller wear
- Parts listed without spline count or roller diameter
