A loose ball joint can be felt as a vague front end and heard as a knock over bumps. It is also a load-bearing part of the suspension, so a worn joint is worth replacing rather than living with.
Whiteline rates the install as difficult and lists about 1 hour. An alignment is required after installation. Other Whiteline parts we list for the Mustang: Front Sway Bar Link Kit, Front Control Arm Lower Inner Rear Bushing, and Rear Upper Control Arms.
Features
- Play removed: Removes the play and looseness that worn factory joints develop.
- Durable build: Durable materials stand up to high loads and constant suspension movement.
- Geometry: Helps hold correct wheel alignment and suspension geometry.
- Replacement joint: Restores steering precision and smooth articulation at the control arm.
- Serviceable: A grease fitting is included, so the part can be re-greased as it ages.
