JIBBBY Posted January 6, 2006 Share Posted January 6, 2006 Could be an out of balance drive shaft but not likely, does it only rattle at higher rpms? What else, maybe a bad shock can you locate where the noise is coming from? Could be alot of things. but check your wheels first and make sure they are all balanced. Check all shocks see if any are loose. Check all exhaust, shake eveything and see if anything is loose and rattles. I need to know when the rattle occures at what speeds and rpms, does it rattle when you brake? If it is a vibration at higher rpms check driveshaft balancing, motor and transmittion mounts. That is what I would do. Quote Link to comment Share on other sites More sharing options...
SirSam Posted January 8, 2006 Share Posted January 8, 2006 I get the vibration from 1k rpm's to 1.8k rpm's when accelerating in park or neutral, I assumeed its motor mounts but not sure. Quote Link to comment Share on other sites More sharing options...
JIBBBY Posted January 8, 2006 Share Posted January 8, 2006 That definetely sounds like motor or and transmission mounts. Check it, good luck..... Quote Link to comment Share on other sites More sharing options...
soarer_bang Posted January 11, 2006 Author Share Posted January 11, 2006 thank you guys~ actually i should say i feel..not hear... not noise~ it's more feel... i feel the rattle around 0~30 mph.. RPM doesn't matter...low speed i can feel it well.. should i check mounts for engine and trans first? Quote Link to comment Share on other sites More sharing options...
Micah Posted September 14, 2006 Share Posted September 14, 2006 Mine makes a similar sound as well, like a rattling under the shifter. Mine also vibrates b/w 1k and 1.8k. I have been told the vibrating is the motor mounts, don't think they can make the rattling though. Mine mostly comes when I slightly let off the accelerator. when I'm coasting b/w 10 and 35 mph, mine will also make like a clicking sound. Almost sounds like gears meshing together with no lubrication. I'm guessing its the drive shaft support bearings on mine? Don't know though.
