:bang head:This is my first post but wanted to thank you guys for coming up with answer to rear shock squeak/groan on my 2004 Midnight Venture with 26K -- I know, little mileage for Bike. I bought it a year ago with 5K on it so I've been riding. Shock held air and no oil leak, but it started to groan loudly when sat on bike. It was even louder when I put extra air in shock. Took advice of removing shrader valve and lubricate with oil. I chose to put a couple ounces of WD40 in shock by jacking rear wheel off ground and placing WD in small funnel connected to valve with clear plastic hose. A couple times of slowly lowering it to compress shock a little and raising it back up drank the liquid. Went slow not to have air blow liquid all over bike. I put rag around funnel and over the top to help prevent this. Guess what, after first ride, the squeak/groan stopped. Thanks again guys... you helped me zero in on problem. Hey, if you are removing shocks from new bike with same symptoms, the old shock might be still good.
