Hi Lexusers -

My 2010 RX350 (~30k miles) recently has been making a squeaking noise when I close my rear lift gate. Sounds like the squeaking is coming from the left side "Rear Door Hatch Support" ..i believe that is what it is called.

Any other owners have this problem? Is this something I can WD-40 and lube? Car is under warranty..

Thanks!!

Back up the truck! WD-40 is NOT a lubricant. It is merely a rust/corrosion preventative for bare metals. It does have some ability to clean stuff, but should NEVER be used as a lubricant, as it gets very gummy & sticky over time. Try a Teflon spray lube, or some plain old oil. BTW- penetrating oil is not a lubricant either.

If your truck is under warranty, let the dealer fix it. Why mess with it?

Use a thin silicone lube, lightly wet a paper towel with a bit of silicone and wipe the shafts of the struts. Don't leave a lot of silicone on the shafts as it can attract dirt and dust. The silicone should just make the shaft slippery. You might also look to see that the pivot points are not causing the squeaks.

WD40 is not suitable for this.

Thank you, gents. I do have the plain oil as well as the silicone lube so will give those a try. If all else fails, I'll take it into the shop.
