W57 Rattle when coming off throttle. Like a type of vibration.

It seems very much from inside the gearbox. You cant feel it through the stick though. Mounts are all good.

Ideas ?

new problem? changed anything since it wasn't doing it?
solid centre or sprung centre clutch?

If not clutch or release bearing it could be the xmember that's getting a tad old maybe and falling apart...?

Its a recently installed W57 into an AE86. New clutch went in at time of install. X member etc is all solid.

The W57 was purchased 2nd hand, so its a bit of an unknown quantity.

Assuming the noise is from within the gearbox, what would it be ?

Have you struck that problem too?

by **NZ_AE86** » Fri Aug 11, 2006 11:00 pm

Yeah, Solid centre clutch = gearbox noise/chatter that is not being dampened so you can hear it when the gears are not loaded.
I have had it in a few cars. Some people can't handle it and have to put a sprung clutch back in!

Another simple possiblity is what I had on my w55. The metal cup on the gbox end of the drive shaft/yoke kept coming loose.

Could feel it through the gear lever too.

Didn't figure that one out until I'd taken the lot out! :roll:

Yup. Struck that in my old EVO.
Put a std clutch in it to sell it as no one would by a car making a noise like that.

I get a chatter when i'm acclerating from a high gear from low rpm,, eg acclerating from 20 in 2nd etc. stops after u reach like 30-40.

Might be something diff though (i have no help as to what the hell it is

)

Perhaps not what you are experiencing, but in some solid mount boxes ive been in before, a lot of rattle etc is transmitted through a solid x member

I think i used the wrong term there, its not a solid mount.
Its all tight and well mounted. It still retains the AE86 gearbox rubber mount.

So does it have a solid centre clutch or not?

Simple answer is i dont know, but will be asking the question.

Does it only do it on deceleration? My last Cef did that, almost sounds as though theres' a bolt or collapsed bearing inside the gearbox? Is there a fair bit of vibration in the lever, but only on deceleration? I thrashed the tits off mine, with no problems, but it did whine a fair bit as well. Maybe open it up and have a look?

yes, only when deaccelerating. You cant feel anything through the gear stick though.

Yeah. I'd put my money on a dodgy bearing.

I've decided to pull it down and do the bearings, so fingers crossed.

If it has a solid centre clutch I would not waste your time doing the bearings, been there and done that! If it has a solid centre clutch (which you will know when you pull it out) replace the plate with a sprung centre and see if it goes away. If you heard the noises my car makes you would swear I need a new engine/gearbox/diff and suspension too!

If you heard the noises my car makes you would swear I need a new engine/gearbox/diff and suspension too! But these noises are all meant to be there. You just can't hear them in a road car as everything is designed to be smooth and quiet so everything is dampened - springs in the clutch - rubber suspension mounts - smooth LSD's - everything!

Of course if it has a sprung centre clutch then it could well be a bearing! Also your driveshaft may be too long.
