My Tilt/Telescopic Motors are acting up on my '05 LS430. This is a problem area for this particular model. It appears a very inexpensive bushing (45768) will help with the tilt so I am gonna give it a try. I read in a bunch of write-ups where they are simply spraying white lithium grease on the gears for lubrication. I also read where the correct grease to use is "Lexus Lithium Disulfide Body Grease." Do any of you know what I should use to lubricate these gears?
