Just wondering if any of you guys got any vibrations after fitting one of these?? or was it just as smooth as before?

 

when im on the slow down from some speed i get really bad vibration and a deep woo woo woo woo noise is the best i can think off

 

Or a duff diff or hubs or a driveshaft??

you shouldnt get any vibration tbh .. thats the hole point when u have a new on that its all balanced up ... or should be

No vibrations on any speed and silky smooth drive

No vibration from the prop, but with having spacers on the front end, i get a vibration at 60 due to knackered spigot rings :biggrin:

I get the same but I thought it might be something to do with my decats. I fitted them both at the same time so don't know which one to blame.

Easy one to sort out t.mogsy. Is your vibration RPM(exhaust) or speed(prop) dependant?

Dave, it could be shagged gearbox mounts or differential bushings. A key upgrade when fitting a single piece prop is to fit the NISMO transmission mount as stock ones can sag over time.

Might sound silly but unhook the diff end turn 90 degrees try again, repeat. Maybe the prop isn't in the right position. I seem to recall about marking the prop against the diff to maintain balance. It might be a moot point but it's an easy thing to try and check.

Pretty sure that's only the case when you're aligning a stock prop with the carrier bearing still in situ.

Thanks everyone but I have figured it out. I've ruined my car lol!!!!

 

Basically everything on my car is now poly bushed, every possible one and the subframe bushes are the solid one, so with zero play in anything I am feeling every vibration from the exhaust and the engine. I get the vibration in any gear at any speed over 4000 rpm but only on the slow down. Put the clutch in its smooth as silk.

 

So in a way I have bolted the engine direct to the body. Vibration is going down the prop into the diff, through the poly bush into the subframe through the solid bushes and into the car.

 

It like a bloody race car the feel and sound it gives or like the f40 kind of thing, now I know the car is safe its sounds mental and is fantastic. Proper raw feel lol the handling and turn in is just immense

 

But normal driving its smooth as so I get the best of both

 

Happy now but still need a diff lol

Get it set up, corner weighted etc. You still got stock engine and box mounts? Can wait to go polybush crazy.

When u push the clutch the prop is still spinning so if it was prop would vibration not still be there...

your decats are probably touching somewhere.

I ruined my s14 by poly bushing everything, wont make that mistake again

Dave,

 

I have solid mounted subframe and diff mounts, poly gearbox mount and bde engine mounts, I don't get these vibrations. the only side effect I get is you hear the diff whine, which I think is cool

PS reading it all does sound like the diff is shagged, the engine decal going through the diff is causing the vibrations, when you push the clutch in the engine decal forces are no longer going through the diff ...

Oh yeah the diff is buggered. It clunks like mad some times you get 2in one change so it is shot. But the bushes will not help, if it was a Orem set up it would probably be fine.
