Grinding, whizzing Noise & stuttering
« on: March 03, 2022, 09:26:49 AM »
Hi all,

New member here, proud owner of a Honda Jazz 2003 plate in green (although it's pretty faded now!!)

Recently, I have had a few problems with it:-

Problem 1 - when stationary and engine is running, if the clutch is up there is a fairly loud grinding/grainy noise. This goes away as soon as I push the clutch down

Problem 2 - similar grinding /grainy noise coming from the car when I am accelerating in 1st, 2nd or 3rd gear. I think the noise is still there in 4th and 5th, however I can't hear it due to other noises. This noise is also present when I am free rolling down a hill with the car in gear (clutch down). If I take the car out of gear, this noise stops (however problem 1 noise happens if clutch is up).
This noise seems to 'speed up' and 'get higher pitched' as the car picks up speed

Problem 3 - stuttering when trying to accelerate. This happens only when the car is warmed up (doesn't happen at all for first 10 mins of running). It's a single judder that is sometimes followed by additional single judders. Happens when I am trying to pick up speed fairly quickly and am towards the lower end of the revs (2k ish). If I put the clutch down, pick up the revs and then ride the clutch a bit more it overcomes this problem. Is also overcome by gently pressing the accelerator down (no good for when you are on slip roads and trying to pick up speed quickly!!)

Any help would be appreciated, apologies if anything wasn't clear!

Gearbox bearings will make that noise, juddering will be  EGR or maybe the rear 4 spark plugs have not been replaced since car was new ( the MK1 Jazz engine has 8 spark plugs and usually only the front 4 get replaced ).  The gap in rear spark plugs could well be 3mm by now, and most of the rear coils FUBAR.   Plenty of info on forum about gearbox noise, EGR and spark plugs.

In neutral with clutch not depressed the gears in the gearbox will be turning and making a noise, when you depress the clutch pedal it means the gears stop turning and that is why the noise goes away.   The EGR valve ( exhaust gas recirculation ) should be closed at lower revs and only open above about 3000 revs to allow some exhaust gas into the inlet manifold, this is to 'cool' the combustion and reduce oxides of nitrogen ( NOx ) which are formed at high temperatures.  If the EGR is dirty and stuck open the exhaust gases can get into engine at low revs,  where they really mess up the fueling ( like having a leak in the inlet manifold ) causing engine to run rough and jerk.   If the rear spark plugs do not get changed and the gap gets too large ( should be about 1mm ) this causes the coils to develop more voltage to jump the gap, this extra voltage can fry the electrical insulation in the coils - the coil is then FUBAR and no longer producing a spark.

I agree. Gearbox input bearing and rear spark plugs. The gearbox will run forever. it will just get noisier. I paid £324 to have mine repaired by a transmission specialist when it got too embarrassing.

Just an update for anybody with the same issues:-
Problem 3 (stuttering) was fixed just by changing all 8 spark plugs. Cleaned the EGR first but that didn't sort anything (although it didn't harm anything!)

Grinding is getting louder on other problems (especially 1)  so will contact a transmission specialist just to get a price. Not too bothered about the noise, just worried it will pack in!

Don't worry about the gearbox noise. I'm refusing to replace mine as an experiment.  :D

I have a noisy input bearing since about 80,000 miles. I'm on 149,000 miles and it's the same noise as at 80,000

Either the gearbox kills my jazz or rust does.  ;D

If I take it gently there's no gearbox noise so it really doesn't bother me too much.

Ah nice! Will leave it as it is then! Only on 88k miles so hoping to get a few more years out of it yet!

Will just be a noisy few years    :D

Cheers for the reply!

Mine started at 90K and by 101K I took it to get fixed. It was only about a month before that that my wife asked me "What's that noise?" so maybe it wasn't that bad.

Ah nice! Did you only go and get the bearings changed and that fixed it? Did you ask them to do that or did you just take it down and ask what they thought?

Mines getting so much louder fairly quickly so thinking about doing it once if passes the next MOT   :D

The noise comes from one bearing on the end of intermediate shaft.  The gearbox will never fail, just get noisier and move up from 1st to second etc.   Due to the helical ( angled ) teeth on the gears a thrust force is applied to the bearing ( helical cut gear teeth are quieter in mesh than straight cut gears,  but not a strong ) and this causes a bit of extra wear on bearing ...   Cars that have done a lot of local, lower gear, start stop journeys develop the problem at lower mileage than cars with more 'motorway miles' in higher gears because the lower gears put more thrust on the bearing.  Me and my wife had identical 53 plate Jazzes, she did local journeys while I did a long daily commute - her car developed the noise at about 60 to 70 K, mine never developed the noise even at over 120K when I traded it in.

As soon as I spoke to the transmission specialist he knew what the problem was. He reckoned he repaired one a week. I dropped the car off one day and picked it up the next. He supplied and replaced all the bearings, seals and fluid (don't know how but he didn't even take the gearbox out of the car). He phoned me the next day and I went and picked it up. It cost £324 and came with a 12 month, unlimited mileage warranty. As I drove it home I could not believe how quiet it was. Four years and 48K miles later it is still the same.
I don't know where in the country you are but it was Top Gear in Rutherglen I went to and Robin was the main man.

I have had the same issue with my 2004 Jazz. I was told when I bought the car (around 4 years ago) that the bearing had been recently changed, however the same noises started about 18 months ago. It's not that loud (yet) and so for now I'm leaving it and will see how much noisier it gets in the future. It was a reasonably low mileage car when I bought it (and just over 81,000 miles now) so I can only assume it was driven for very short journeys with the past 2 owners. It's reassuring to know that a repair isn't ridiculously expensive...

Just an update:-

Got quotes ranging from 650-850+vat for bearing replacements at places near to me. Quoted 320+vat from the place in Scotland that can do this in situ that Jocko recommended but it's just a bit if a treck for me in Derby, Midlands. May be on the cards in the future though

For the extra £300 you can take a nice drive up and stay in a smart hotel for the night.
