Car: 2004 v70R GT
Driving to work today I got the rain squeal for the first time had the car about three weeks now. It had the stock exhaust along with the EBD. After work I headed over to a muffler shop and had them take the resonator out and weld in a straight pipe (wish I had a welder at house since I can weld…)
After they were done and I left the shop I was getting a loud noticeable rubbing or grinding noise also kinda sounds like trans gears grinding with no oil doesn’t sound good at all. Happened whenever decelerating or no accel load on drive train. I turned right around and went back to shop and they put it back on lift and we checked it and I couldn't find any rubbing. I even grabbed the exhaust and shook it around and lifted it up and couldn't find anything its got tons of room now??
So I left and listened to it all the way home which was a few miles. It's weird it instantly goes away when I apply a load to drive train with engine. I can two foot car and stop and it doesn't make noise while drive train is loaded. Also it drive fine under acceleration too.
It has me believing it could be a bearing in drive train or a universal in drive shaft?
You guys have any ideas of what it could be. I’m pretty bummed about it I’ve had car less than a month?
I got a warranty with car but it’s not a cpo car. I’m calling stealership tomorrow and make an apt to have it looked at. I hope pulling resonator doesn’t void warranty
Thanks for any help.
