Retightening of Front Upper Arm Mounting Nuts (Chassis - 017)

Description

Some AMANTI (GH) vehicles (produced prior to May 31, 2006) may exhibit a creaking, knocking noise from the front upper arms while braking. Lateral movement of front upper arms due to loosened upper arm mounting nuts could cause this noise. Before replacing the upper arm assemblies for such noise, tighten the upper arm mounting nuts according to the procedure outlined in this TSB.
