Hey guys i have a 2007 wrx with 41k and i have just noticed today that when in reverse while the clutch is engaging i hear a grinding noise. The noise is hard to explain but it just sounds like a deep, scraping metal sound. It doesnt sound good but like i said, it's only happening at the point where the clutch engages in reverse..and it sounds like its coming from the rear of the car. Once you get the car rolling in reverse past the point of engagement there is no more grind it's just the actual clutch itself engaging when you hear the grind. No grind in first. And just did tranny and rear differential fluid with subaru extra s. Any help is appreciated.
