Vibration in pedal - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

NickS14 · 10-04-2012, 09:33 AM

Experiencing some vibration in my pedals, has recently been getting worse... Seems to be more prevalent at high speeds, the vibrating is like similiar to a pulsing or like something is loose.

Also, it seems to be more apparent during turns, is intermittent.

Just curious if anyone has ever experienced this. ('95 S14 KA24DET)

*It is not vibration from wheels being unbalanced or anything like that, I know what that feels like and this is totally different.

Many Thanks

The pedals... Feels like it could be susp., brakes, tranny.... not sure, but I don't know if feeling it in the pedals is typical for certain mechanisms going...

Vibrations - Tire Balance , Tierods / suspension , Driveshaft / Center carrier bearing , Universal joints , Engine mounts , Tranny Mount. Feeling it in the pedals and None in the steering wheel ?

Nothing in the steering wheel, only the pedals....

Any way to test the lot of those suggestions?

And thats why its weird...feeling vibrations on the pedal, there isnt a whole lot of things thats mechanically connected to them that could cause vibrations. If its affecting the pedal, you should be able to feel where its coming from since you should feel it all over the car. Gas pedal is only connected to the engine by a cable and shouldnt feel vibration from that. Clutch pedal is hydaulic and connected to just a slave cylinder, if the whole transmission is vibrating, you'd feel it underneat you and the shifter. Brakes, only time you shoud feel anything is only when you're braking...

Ya, pretty confusing to me as well, I'll have to get underneath and check it out... I mean there is a little vibration in the shifter, and steering wheel, but I know that's from the 18'' G35 wheels I just put on without balancing... This is a different type of vibration....

Also, seems a little more prevalent when turning....

I had bad vibration , due to bad tie rod but again it was all steering wheel and front end. I would say the fact that you put tires on without being balance is a big no no work trying to hunt down any vibration , Get yo SHit balanced , process of elimination. But a pedal vibration only that would still have to come from chassis vibration , Tire balance and new engine and tranny mount which probally have over 100k on them and more that a decade. (if they havent been replaced yet).
