Adjustability
On the 2018 Ram 3500, not all alignment angles are directly adjustable from the factory. Understanding what can and cannot be changed is crucial for proper diagnosis and repair.
Front Axle:
- Camber: From the factory, front camber is not directly adjustable. If camber is outside the specified range, it often indicates worn ball joints, control arm bushings, a bent component, or frame damage. Aftermarket solutions like eccentric cam bolts (e.g., from SPC Performance) or adjustable control arms can be installed to allow for camber adjustment.
- Caster: Front caster is adjustable on the Ram 3500, typically through eccentric bolts or cam washers on the lower control arm mounts. This adjustment allows the technician to fine-tune the steering feel and stability of the truck.
- Total Toe: Front total toe is adjustable via the tie rod ends. This is the most common and critical front-end adjustment, directly impacting tire wear and steering response.
- SAI (Steering Axis Inclination): SAI is a non-adjustable
