Gearbox clunking noise.

[joe boy micra]

When the car is in neutral and you put the gear stick from side to side it makes a clunking noise.

I have had a look and the noise is made where the gear linkage goes into the gearbox.

I drew a pic to help yous understand it. :blush:

Anyone any idea what it is? also its hard to get into 3rd gear.

Cheers

Just to update.

I went out and spent 30 mins ripping off the heat shield getting rust in my eye and having a terrible time.

anyways the return spring is broken. So off to Nissan tomorrow for a replacement.

Hope this sorts it.

 

[joe boy micra]

I have just fitted the spring and its stopped the clunking noise.

But when its in 1st or 2nd and you put it back into nutral its not returning to the middle.

anyone any idea what I could look at now?

I have took off the rubber double joint at the bottom of gear linkage and have greased it up.

Leaving it to sit for a while until I put it back on.

Can anyone help at all?

spring should have reasonable tension not too loose
if it is strech'd cut it back a little and remake the hook shape

well said that man (Y) it needs to be just the right length that its under tension in all gears eh

if i remember right with the spring off one side only has bounce 1st & second gear side ?

 

[joe boy micra]

I replaced the spring with a genuine nissan one this morning.

I took the double joint off and put it back on but its still not centering properly.

 

[joe boy micra]

Does anyone know if the universal joint should be solid?

or should I just do it up tight enough that there is movement in it?

I think if its not too tight then it will solve the problem. Its pouring down in glasgow so will be tomorrow before I get to do it all up.

paul (polly p) totally stripped his joints and greased them up iirc (covered in his blog somewhere

I have just FIXED the problem.

I had over tightened the universal joint after greasing it up.

Its now working perfectly.

I might do a wee how to soon.

Shaun has the right idea..... whenever you direct someone to your blog for whatever reason you should do it like:-

Step1.

Remove heat shield above cat. This is done by removing 5 10mm nuts. There is 4 nuts into the chassis and one nut into another heat shield.



This is a picture of the heat shield taken off. Two of my bolts would not come undone. I used snips to snip the heat shield to get it off.

Step 2.

Inspect spring. If it is like mine then it will be snapped.

This is a picture of the new spring fitted.



The new spring was less than £9 from Nissan.

Step 3.

Remove universal joint. This is done by taking out the two bolts that go through it. One is 12mm and the other is 13mm. You will need two rachets preferably.

When you have undone the two bolts then use a screw driver to lever out the joint.

step 4.

Greasing the joint.

I greased up and lubricated the joint. I let it sit in the grease for a few hours.



This is a pic of the grease and penetrating fluid I used. Cheap pound shop stuff.

step 5.

Refitting the joint.

Put the joint in and do the nuts up finger tight. Get someone to put the car in first gear then take it out gently. The gear stick should spring back and settle in the middle. To check this push it straight forward and it should go into third gear with no problems.



Start to tighten the nuts and keep checking that you do not over tighten them.

I did this the first time as I did not have anyone to help me :blush:

The reason that it stops springing back is because the universal joint is solid. There should be a nice movement in this.

DO NOT OVER TIGHTEN THE NUTS.

I would of liked to get more pics but I have a white BB bold so taking pics with greasy hands is a no go.
