Both technicians are correct because both shims and cams can be utilized to adjust rear toe alignment on various vehicles.

The use of shims is a traditional method that involves placing thin pieces of material between suspension components to alter their position, thus affecting the toe angle. This can be particularly common in vehicles that use leaf springs or specific types of rear suspension systems where minor adjustments are adequate.

On the other hand, cam-type adjustments are often found in more modern suspension designs, allowing for more precise control of alignment angles. Cams can be rotated to shift the position of the suspension components, making it simpler and more effective to achieve the desired toe angle.

In summary, both methods—shims and cams—serve as viable solutions for adjusting rear toe angles in different vehicle suspension setups, which is why the choice that acknowledges both technicians is accurate.
