FX35 Loud thud sound

Discussion in 'FX (03-08) - Engine & Drivetrain' started by LeBron23, Sep 27, 2007.

  1. Ok...I just noticed this after doing the 60K service...

    1. I assume transmission fluid is leaking somewhere and my belly fan has beautiful green liquid all over it. Not much but some drips here and there.

    2. From a stop, I give it a quick gas I hear this thud/Clunk! sound right underneath my butt. I thought maybe Exhuast hook is dried(I read something like this on org.) so I sprayed WD-40 but didn't fix the noise. Most recently I added LMS Intake but I don't think that has anything to do with it...It is definitely coming from underneath the drivers side...
    Any idea? Help my beat up FX with 350Z motor, new tranny, new rear axel and also diff. with one broken tooth.

    Sorry Min I can't help out but the green liquid sounds like coolant leak somewhere. I suggest taking it in to LMS and get it looked at. Man it seems you are having car troubles left and right. It seems you have very little luck with cars.

    I did some search...over filling coolant could cause some leak? I do see some transmission leak though, Infiniti of Santa Monica fixed transmission leak when they fix the fuel tank leak. I guess I abused my FX too much now it can't handle anymore haha
    poor FX.

    i dont think over filling your coolant would cause a leak, thats why you have the coolant over-flow tank, but green liquid should be your coolant.
    i remember when i installed my plenum spacer and forgot to put my coolant line back to my plenum i got a nice splash of coolant all over the place lol. hope you find out what is going on and get it fixed

    as for the thud...i got no idea what it could be, i guess your FX isn't pairing well with your transplant...

    as for that loud thud...you probably hit paris hilton and have been draging her for many miles since then.

    bad radiator cap could cause this? I don't know I'm just trying to figure it out by myself since I don't have time to go to LMS this week, must drive up to Santa Barbara...I might stop by the dealership on my way.

    hahah, you searched!

    Shocks/struts are probably not covered under warranty unless it was really premature wear.
