ES 300 V6-3.0L (3VZ-FE) (1992)
Additional squeak/groan noises have also been found to originate from the rear suspension upper insulator and/or the rear strut rod bushing. The areas
shown below should be lubricated with a silicon or lithium based grease on any ES 300's with complaints of rear suspension squeak/groan noises. Proper
lubrication methods require disassembly of the components to ensure adequate coating and penetration.
