5. Apply a liberal amount of grease, P/N 12345996 (in Canada, use P/N 10953501), both underneath and on top of the front and rear tip inserts for
the #2 and #3 leaves, as indicated below. A screwdriver can be used to gently pry up the tip insert; however, a rag around the screwdriver must be
used to prevent damage to the spring. Use a flat-bladed tool, such as a gasket scraper to properly distribute the grease.
6. Lower the vehicle to the ground and test drive to verify the repair.
Please inform the customer that this will offer relief, it is by no means a lifetime repair. Periodic cleanings and grease re-application may be necessary
throughout the life of the vehicle.
For 1500 Series (1/2 ton) models only: On vehicles built prior to October 2004, if the above procedure does not correct this noise, it could be caused
by an incorrectly dimensioned splay clip (the band holding the ends of the leafs together) that interferes with the leaf springs. A 5 mm (0.197 in) wider
splay clip was introduced in early 2005 model year to provide additional clearance. To correct this concern, replace the rear leaf spring assembly. There
was no change to the part number.
