2004 WRX rear end rattle/noise/something after bushings

Frank-i-e · 12-25-2012, 08:26 PM

Hey guys, after my friend installed the TiC rear diff bushings he began to hear a weird rattle grinding noise. During normal power band the car makes no alarming noises, however when the car is SLIGHTLY or greatly lugged the noise becomes prominent. Any ideas? Here is a sound clip.

Okay, so he came and picked me up and went out. It's coming from the middle of the car. Carrier bearing? U joint? Any experience with such noises coming from those specific parts?

Thanks guys!!!!

Did you guys check that the downpipe is NOT hitting the trans X-member?

Also check the two plates right in front of the rear wheels.

I'll check those. We didn't have jack stands so we didn't get under the car. 39° and 40 mph winds suck too! LOL

Ya I know what you mean. Guna take my car into Synergy tomorrow. I can't every remember having any one fix somthing on my suby, but its to cold & I don't feel like pulling the trans in the cold.

I have had grinding noises from the rear in the same circumstances as you (on deceleration or off throttle) since the install of my RACE differential and outrigger bushings, but nothing that noisy. I've assumed it's normal since day one of the install because of the "added NVH" disclaimer.

Yeah, that should be more of a humm or vibration. I have the same bushings in my 05 STi that his WRX does and no noises at all so his isn't normal at all.
