Is there any difference with the clutch pedal to the floor, or with the clutch pedal released.

Could be a clutch spiggot or release bearing.

Neutral would pretty much restrict any gearbox probs to the input shaft (lay shaft not energised by selectors) or its support.

yeah mate only noisey with clutch out...........

Does it make the noise with the clutch partly pushed (taking up the slack, first 1-2cm of travel)?

I would be doing the clutch (+ asscociated bearings) when you are in their anyway.

jumped in her just to check and on about halfway out the windy noise starts.... is this hard to repair or take it to a mechanic ?????

Nothing should be too difficult in a zook.

Is that point at where the noise starts where the car would normally start to take of (if it was in gear), or is it at the point where the clutch would be almost fully released?

Explanation:
The distinction here is important. If the throwout bearing is on its way out, then light pressure on the pedal (not actually disengaging drive) will usually quiet the bearing. If the input shaft bearing is gone then the noise wont quiet until the clutch has fully disengaged the drive.

it is where the car starts to take off how much would this cost to repair....

cheers sako.................

Sounds like the input bearing, then.

As far as costs go, I dont think it would be much to do the bearing alone, but the best bet would be to do everything while you are in there, clutch + bearings included, so you know exactly where you stand.

Nothing on the Zook is complicated, so you should have a reasonable shot at doing the work yourself if you are half competent with a spanner and have a decent sized garage.

Even if you could get the gearbox out and take it to a mechanic with the overhaul pack it shouldn't cost that much.

Clutch is easy to do with the gearbox out. Remove pressure plate, remove spiggot bearing, remove clutch release bearing, inspect flywheel (may need to remove and get it resurfaced), and replace everything with the new stuff. Worst part is having to work under the vehicle to do it.

Sounds complicated but is very straightforward and logical once you see everything.


Before I get shot down and flamed, I have not done this on a Zook, but have done it quite a few times to my and other mates vehicles.

thanks GARYINOZ for all your help and by the way are you a van halen fan by any chance ???????????????????????

cheers sako................

I pretty much agree with what Gary said. The most common prob in this area is the clutch thrust bearing, they dont like water and mud, and die often. I am assuming thats vits are similar set up to sierras.
It is best to get other stuff checked while its apart, too.

I have the exact same problem with my 1990 SWB hardtop, 1.6 carby vitara.
Noisy bearing with clutch out and transmission in neutral and no noise when clutch is in.

The problem was there when I bought it six years ago and is still there now (I'm waiting for it to get worse before fixing). The car has done 360,000Klm and still goes great (driven daily).

If your noise has only started recently. I suggest you monitor it to see if it worsens. I try not to let my car idle in neutral for long periods and when any gear is engaged, the noise dissappears. My noise is worse at fast idle (choke on) and mostly dissappears at normal idle.

Hope this helps.
