I have an irritating squeal that sounds like it is coming from the front muffler area. But noises and where they are originating from can be difficult to pin point. When I start out I hear the squeal/screach when accelerating but then it goes away. Most prevalent in gears 1 thru 3. I plan on installing the 1320 header and variable exhaust when it becomes available. I am hoping that fixes it. Any ideas what could be causing this? 2015 SL with no modifications. I did change the rear end oil with 75/140 Royal Purple but that did nothing. Oh, I have 18,000 miles but this started around 16,000.

Pardon my ignorance, but are you supposed to grease that area regularly or is it one of those 50,000 mile maintenance things?

I've used the needle for my last 4 u-joint greases. It has always been a bitch to get it to fit without missing from the back cup holder position. Then I saw a thread that said to remove BOTH cup holders. Wow, that worked. Remove both and grease from the front cup holder. Worked the first time because the angle is perfect to get the needle seated properly and you can see what you are doing.
