29430, Sleight Vibration at 3700 - 3900 RPMs
Posted by Kahn, Aug-04-02 02:24 PM
Hey guys,

I have this weird vibration (slight but annoying) that comes through the steering wheel at around 3700 - 3900 rpms - in any gear or out of gear.... I have no idea what it is... I also have some sort of exhaust rattle that I can hear around 3k. The vibration started after I had my clutch installed in an emergency - any ideas?? Thanks all.

That's what my car did before the rod bearing spun. Hope that helps.

Okay...someone explain exactly what this means - and can I stop this from happening - how long did your car do this for before it spun the bearing - were there any other symptoms????

ok does the vibration START at 3700 rpm, and continue through all higher rpm... or is it JUST between 3700 and 3900??

Yea man, it sounds like you've got a spun rod bearing, that's exactly what mine was doing however it's louder if you pop the hood and listen and mine was at different RPM's mine was around 2600 - 2900 and I found out it was my 4th cyl Rod bearing that was spun... sucks but true!!

You guys got to make sure you have oil in there. Check it often and it should prevent spun bearings.
29438, I refuse to accept this diagnosis.....:-(

My oil is changed on the dot at 3000 miles --- this problem started right after I had my clutch changed - I would lean more towards an improperly installed clutch or something else to that effect rather than a spun rod bearing. One other thing I just noticed is that it is more prominent when I am decelerating (foot off the gas - and the gears are slowing me) then when I am accelerating - I am going to have it checked out tomorrow by a local mechanic - but anyone else got any ideas?

Thanks.
