"C", "G", "K" & "P" (Frame Angle)
WARNING: This page does not describe the selected car, but rather 64 other vehicles, including the 1999 Pontiac Montana, 1999 Oldsmobile Silhouette, 1999 Oldsmobile Bravada, 1999 GMC Yukon, and 1999 GMC Suburban. However, it is still accessible from the selected car via links, so may be relevant.
- Position vehicle on smooth, level surface. Using inclinometer or bubble protractor, measure frame angle. Determine if frame angle is up-in-rear or down-in-rear.
- To determine corrected caster reading with various frame angles and caster readings apply one of the following rules:
- Down-in-rear frame angle must be subtracted from a positive caster reading.
- Up-in-rear frame angle must be added to a positive caster reading.
- Down-in-rear frame angle must be added to a negative caster reading.
- Up-in-rear frame angle must be subtracted from a negative caster reading.
If corrected caster is not within specification, adjust caster to specified setting.
