2005 – 2009 Tacoma Body Type(s): Access Cab, Double Cab, Regular Cab Drive Type(s): 2WD, 4WD Engine(s): 1GR, 2TR Transmission(s): 6MT, 5MT, 5AT VDS(s): JU62N, KU72N, LU42N, MU52N, NX62N, PX42N, TU62N, TX62N, UU42N, UX42N Introduction Some 2005 – 2009 Tacoma vehicles may exhibit a squeak noise coming from the rear suspension when traveling over bumps or rough road surfaces. The squeak type noise maybe caused by the rear leaf spring pads. A newly designed leaf spring silencer has been made available for this condition. Silencer Pad Procedure NOTE Perform the following procedures on both the RH and LH sides of the vehicle. Rear Silencer Pad Replacement 1. Place the vehicle on a lift. 2. Using a pry bar, separate the two main leafs, allowing access to the spring silencer pad installed on the lower leaf of the spring pack. CAUTION Be careful NOT to scratch the spring surface with the pry bar, pick, punch, screwdriver or other tools. 3. Use a pry bar as a wedge to hold the leaf springs apart. 4. Use a pick, punch, or screwdriver to push upward on the spring silencer pad from the underside of the spring pack through the access hole. 5. Push the spring silencer pad up high enough to remove it from the spring assembly. Applying light pressure to the back of the silencer pad will be enough to “pop” the pad out of position. 6. Using brake clean or equivalent, completely remove all grease and dirt between the leaf springs. NOTE Remove all grease and grease residue as the new silencer pad employs a self lubricating surface. DO NOT APPLY GREASE TO THE PAD AND SPRING SURFACE. 7. Index the new spring pad so that the locating tabs are facing away from the center of the leaf spring. Using a screwdriver or a pick, center the silencer pad in the hole in the leaf spring. 8. Install the spring silencer pad in the leaf spring pack carefully. It might be necessary to use another pry bar to “seat” the silencer pad into the mounting hole on the leaf spring assembly. Front Silencer Pad 1. Using a pry bar, separate the main two leafs, allowing access to the spring silencer pad installed on the lower leaf of the spring pack. CAUTION Be careful NOT to scratch the spring surface with the pry bar, pick, punch, screwdriver or other tools. 2. Use a pry bar as a wedge to hold the leaf spring apart when removing the spring silencer pad. 3. Use a pick, punch, or screwdriver to push upward on the spring silencer pad from the underside of the spring pack through the access hole. 4. Push the spring silencer pad up high enough to be able to remove it from the spring assembly. Applying light pressure to the back of the silencer pad will be enough to “pop” the pad out of position.
