# RAPPING NOISE FROM ENGINE MOUNT STRUT GROUND TO BRACKET

#### VEHICLES AFFECTED: 1984 'A' Series Vehicles Equipped With 4.3L V-6 Diesel Engine (VIN Code T)

A condition of a light rapping noise or resonance may be encountered with a V-6 diesel engine at idle or coast down. This may be due to a grounding interference between the aluminum strut and the welded reinforcement on the mounting bracket.

To correct this condition, remove the strut from the mounting bracket. Grind " necessary the reinforcement metal on the engine bracket to obtain a minimum of 2.4 mm (3/32 of an inch) clearance when the strut is reinstalled. See Fig. 1.
