Hey all,
I have been getting weird rattles and vibrations on my car. I know what you all may think because it's a "240". Well my problem is after I switch to a welded differential and sub frame spacer, I've been getting weird shakes/rattles/vibrations WHEN I clutch in into reverse, 1st and 2nd (while driving, even on a flat clean surface road). Before when I did not replace my tranny mounts my whole shifter and tranny shakes and feels loose clutching in into reverse, 1st, and 2nd. Now it is just the back section of the car. I am running PoweredByMax sub frame spacers and a welded differential from FLYBERT.

To sum it up my back section of the car shakes/rattles and my clutch feels loose(weird) when I clutch into reverse, 1st, and 2nd

subframe spacers and welded diff are why you get shakes rattles and vibes.

they were there before, trust me. now they're amplified

lol $100 bucks says this is a DD

It's not the vibration that is bugging me, what bugs me is when I shift into gear my whole tranny to the driveshaft and to the rear sections rattles/shakes and something feels loose.

You are partially right, it is my "DD" but I hardly drive my car. :P

just make sure everything is tight under there
this is normal with spacers and a welded diff

Shift_Dr1ft · 08-27-2008, 08:08 PM

Hmm...Alright, everything is tight, triple checked everything. Any possibility that the driveshaft might be going out, such as the U-joint? Just a thought. Thanks tho.

there is a possibility that a lot of shit could be going out, and it will do so a lot faster with weld diff and spacers

get under the car and have someone bang through the gears, find out what exactly is making the noise

Shift_Dr1ft · 08-27-2008, 08:21 PM

Alright, how do you check/know when a U-joint is bad?

koukimonster139 · 08-27-2008, 08:25 PM

mm if its that bad, grab the driveshaft and shake it maybe it will be loose
or usually they just fall apart

Shift_Dr1ft · 08-27-2008, 08:28 PM

Alright, I will give that a check, thanks a whole lot!
