Ball Joint Relocation Kit for Lifted Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for relocating ball joints in suspension lifted or modified vehicles require drilling out the OEM steering knuckle, which weakens the structure, is labor-intensive, and difficult for unskilled mechanics to execute accurately.
Innovation Solution
A ball joint relocation kit comprising a straight-shafted ball stud and an externally-tapered bushing that allows the ball joint to be relocated above the steering knuckle without modifying the OEM steering knuckle, using a straight-shafted ball stud and a reverse taper sleeve that replaces the OEM tapered ball stud, allowing for easy installation without drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the OEM tapered ball stud is drilled out to relocate the ball joint above the steering knuckle, then the ball joint can be relocated to maintain proper steering dynamics in lifted vehicles, but the structural integrity of the steering knuckle is weakened and the process becomes labor-intensive
Solution Approach 1:
The patent introduces a tapered bushing as an intermediary component that interfaces between the existing tapered hole in the steering knuckle and the straight-shafted ball stud. The bushing's tapered outer surface matches the knuckle's tapered hole, while its straight inner surface accommodates the straight-shafted ball stud, eliminating the need to drill out the knuckle and preserving its structural integrity while enabling ball joint relocation
Solution Approach 2:
Instead of modifying the ball stud to have a tapered shaft to fit the knuckle's tapered hole, the invention inverts the approach by keeping the ball stud with a straight shaft and providing the tapered interface through the bushing that fits into the knuckle's existing tapered hole. This reversal simplifies the ball stud design and eliminates drilling operations on the knuckle
2Adaptability or versatility
If the OEM tapered ball stud is drilled out to relocate the ball joint, then the ball joint relocation can be achieved, but the installation process becomes complex and difficult for unskilled mechanics to execute accurately
Solution Approach 1:
The tapered bushing serves as a mediator that simplifies the installation process by eliminating the need for drilling operations. The bushing can be directly pressed into the existing tapered hole in the steering knuckle, and the straight-shafted ball stud can be simply inserted through the bushing, making the entire relocation process accessible to unskilled mechanics without requiring precision drilling skills
Solution Approach 2:
The tapered bushing is pre-formed with the exact taper match for the knuckle's tapered hole, eliminating the need for on-site drilling and machining operations. This preliminary preparation of the tapered interface allows for simple press-fit installation rather than complex drilling operations, significantly easing the installation process

AI summary
A ball joint relocation kit including a ball stud having a ball end, a threaded end, and a shaft with a straight outer diameter, and a sleeve having a tapered outer diameter and a straight inner diameter, wherein the sleeve is adapted to be received in a tapered hole through a steering knuckle from a bottom side, and the ball stud is adapted to be received through the tapered hole and the sleeve from the top side. The ball joint relocation kit can be used to replace an OEM ball stud to relocate the ball joint from below the steering knuckle to above the steering knuckle in suspension lifted vehicles.
