2009 Nissan GT-R: Click Click Click Click Click
August 07, 2009
"I think I picked up a screw." Walton says over the radio after his first pass down the drag strip. "Front left clicking noise?" I reply. "Yep." "Don't worry. It's been happening for a least three weeks. Maybe a few months. It's impossible to notice with the windows up. Windows down and next to a wall, it's all you hear. You'll be fine. Go faster."
Prudence ruled and we checked it anyway. There was no screw. But that click is, and after at least one dealer visit, it's time to get to sleuthing. Off to the internet we go.
Turns out this is an altogether too common problem on 2009 Nissan GT-Rs. See that pic that I posted (Thanks, Dan!)? See anything odd about it? Or anything asymmetrical?
Hint: It's got a yellow arrow pointing to it. Hint #2: Look at the top yellow arrow. Hint #3: There's no top Return Spring Clip (Nissan part # 41090-JF20C ).
So the noise, it would seem from other GT-R owners' experience, is an improperly lubed and improperly supported retainer pin. Nissan, it seems, thought one would suffice. (See the 2008 Subaru WRX Brake Pad Replacement blog for the more common, and correct, way to do this with one large spring clip.) We've ordered the part ($8) and it'll be here next week. Most likely we'll install the item ourselves, but I promise nothing at this point.
