PeterD Posted March 7, 2007 Share Posted March 7, 2007 alright i went on some trails today with the legacy and coming home i have this nasty sound coming from the rear end area. When i accelerate forward the sound goes away, but when i let off the gas there is this nasty grinding sound, its hard to explain. on the highway you cant hear it only when you let off the gas in the lower gears Link to comment Share on other sites More sharing options...

What tranny/motor configuration? More info will help. It might be a rear axle going south. It might be a muffler rattle having been ripped loose while off-roading....

It might be a muffler rattle having been ripped loose while off-roading.... 91 legacy wagon AWD 5sp. the muffler is intact, no noise at all when the car is on the highway. for example, i take off in first gear and rev the motor to 4k then let off the gas, that compression is when i start to hear the grinding type noise. if i put my foot back on the gas it goes away. :-\ Link to comment Share on other sites More sharing options...

There are heat sheilds everywhere, just usually the rear ones arent a problem since they are ont the body and not the pipes. Can maybe be a backing plate too. nipper Link to comment Share on other sites More sharing options...
WoodsWagon Posted March 8, 2007 Share Posted March 8, 2007 Highly unlikely, but it could be the rear diff. I was out "rotating" the tires one night, and I blew the rear diff. It would work pretty well under load from the engine, couple of skips here and there, but it would make god awful noises when I coasted. I drove it home with the E-brake on so it staid loaded. Worked untill the last hill, accidently coasted, crunch the diff was gone. Link to comment Share on other sites More sharing options...

PeterD Posted March 8, 2007 Author Share Posted March 8, 2007 I checked the rear diff oil, its old so i replaced it, checked the back brakes there fine. a few ideas i have are the rear axles, or axle. or the bushings holding the rear end to the car. Im totaly stumped, and i don't beleve anyone will really beable to help unless there in the car listening. i guess i'll let it go till it gets real bad, i just hope i can figure out the problem before i drive to Wistler to go skiing in a month Link to comment Share on other sites More sharing options...
PeterD Posted March 10, 2007 Author Share Posted March 10, 2007 problem solved!!!! so i discovered my problem. this rock made all the vibrations resonate through the car. i removed the rocks and the sound was gone. every time i put my foot on the gas the tourqe would lift that rubber mount up and when i let off the gas it was coming down on the rock and the rubber was un able to absorb the vibrations.

Atook Posted March 11, 2007 Share Posted March 11, 2007 problem solved!!!! so i discovered my problem... I'm glad you figured it out, this is close to what my car has been doing, ever since I jacked it up by that bushing one day. Blew out the bushing. Doh!
