The suspension bushings included with this part can only be lubricated with PTFE grease, also referred to as "Marine Grease". PTFE grease is a very sticky, opaque grease that is water proof and will not degrade the bushing material. If lubed properly at installation, these bushings will not need to be lubricated again. Use of any other grease on these bushings will cause the bushing to fail and any bushing warranty to be voided.
