Hey guys, I have a 2014 WRX and I've had the Cobb front and rear shifter bushings installed for around 1000-1500 miles now and there is a squeak that is driving me nuts. This has been since day 1. I'm 99% sure its coming from the rear shifter bushing. I crawled back under the car today and took it apart and re-litium greased it all thinking that may solve it. And no change in the squeak.
The symptoms are as follows:
When i'm cruising north of 40-50 MPH and the car is warm and everything is expanded and nice a hot under the car, I here a little metal-on-metal squeak when i hit bumps. It doesn't happen at low speeds and not usually when the car is cold. But get it up to operating temp and hit slight bumps and you hear a squeak. I'm not talking about magnified tranny noise BTW, as I knew that may get louder which is fine.
My conclusion was that it was that maybe it needed more grease. But now that I am thinking about it I don't think it is that at all. My take is that everyone complains about how the bolts for the rear bushing thread kind of crooked compared to the bushing it self. At the same time, the Cobb rear bushing comes with metal sleeves for the bolt to go through. but because the bushing is uniformly straight and the bolts thread a bit annoyingly, I am wondering if it is the bolt squeaking up against the metal sleeve in the bushing.
So the questions are as follows: Has anyone else experienced this squeakiness with the Cobb rear bushing? And if so, What was the solution to get rid of it aside from live with it.
I did some searching and couldn't find anyone talking about this, but hopefully I'm not alone! Thanks!
