Some owners of 1991 Bravadas, built prior to vehicle number M2705806, may comment about a knocking or rattling sound coming from the underside
of their vehicle. This sound can occur if the torsion bar support insulator is damaged or breaks. To correct this condition, a new more durable torsion bar
insulator, P/N 15677665 has been released and is currently available from GMSPO. The new insulator is visually identical to the previous insulator and
the installation procedure has not changed (reference service manual, Section 3C).
