There are pros and cons to both king pins and ball joints. Here are some things to consider when making a decision:
King Pins:
- King pins offer a more precise steering feel since they're mounted directly to the steering knuckles.
- They're less likely to wear out as quickly as ball joints since there's no rubber in between the moving parts.
- However, if king pins do wear out, they can be difficult and expensive to replace.
- kingpins can also rust and seize up if not properly maintained.
Ball Joints:
- Ball joints offer a smoother ride since the rubber absorbs some of the bumps and jolts from the road.
- They're easier (and cheaper) to replace than king pins if they do wear out.
Ultimately, it comes down to personal preference and what you value most in your vehicle. If you prioritize precise steering, then go with king pins. If you prioritize a smooth ride, then go with ball joints.
