michy Posted October 10, 2007 Share Posted October 10, 2007 Now and then at low revs I get a very strong vibrating/rubbery grinding sound coming from the rear left side of my R33. Some say it could be related to the muffler/exhaust but I can't see what's wrong. This only happens after 5 or so minutes of driving, usually when I take off from a red light - it's not something that happens as soon as I've started the car and started to drive off. It's very random, as in it doesn't happen all the time I'm at low revs either. Anyone got a clue?

32GTRVSPECII Posted October 11, 2007 Share Posted October 11, 2007 Could be anything really from exhaust to suspension i would check all the bushes and that around the area check that the exhaust isnt hitting anything, and make sur eits not something simple like something moving in your boot or your spare!

adam-__- Posted October 11, 2007 Share Posted October 11, 2007 Your jack in the side of your boot? Link to comment https://www.sau.com.au/forums/topic/188846-another-mystery-noise/#findComment-3404869 Share on other sites More sharing options...
ssshonky Posted October 11, 2007 Share Posted October 11, 2007 is the car super low? could it be the wheel rubbing against anything as the car " squats " on takeoff?

Dragonforce Posted October 11, 2007 Share Posted October 11, 2007 I have the same thing dude, im pretty damn sure it is a bad join somewhere on the muffler/catback. It seems like the same problem, i start the car with no noise but its like after 5 mins or so when the metal has warmed up i get the knocking rumble coming from the left hand rear corner. I'm replacing my entire exhaust system tomorrow so i shall tell you what i find as i pull things off. Just a tip tho, after say a half hour drive park in ur drive way and keep the car idling and get someone to go give the muffler a not so gentle wiggle with their foot while you sit inside the car, positive you will hear the same noise. This set my mind at ease when i was thinking it was suspension related!

Dragonforce Posted October 12, 2007 Share Posted October 12, 2007 Ok man, my new exhaust is on and no noise. So id say its something wrong in the joins somewhere not that i noticed anything as i pulled it all off. Im hella dissapointed in my x force system, its so damn quiet lol..

adam-__- Posted October 14, 2007 Share Posted October 14, 2007 Have you checked if the jack is stuck in its position. Usually it comes out and rattles around.
