New owner - various questions.

[Si Crewe]

Hi folks.

Inherited a 2002 Jazz last night and I have a couple of questions...

Firstly, there's "the noise".
Pulling away from a stop, I'm getting a fairly obvious "scraping/rubbing" noise (sounds a bit like brake pads dragging on a disc) in 1st gear, which seems to be more obvious if I'm pulling away from the kerb and turning the steering.

A quick google search suggests this could be the (apparently) infamous issue with the gearbox bearings.
I might be wrong but I would have thought if this was the case the noise would be present in all gears.
As it is, the noise only seems to be present while accelerating in 1st.
If I pull away in 2nd gear I don't get the noise.

Will be changing the gearbox oil in the next couple of days but, in the mean-time, is there anything else I should be looking at in addition to the gearbox as a likely source of this noise?


Secondly, there's the locks.
The central locking works fine but I can only get the key in the passenger door because the driver door lock appears to be damaged.
The key slot is at a 45° angle, and the key won't go in.
The lock doesn't look damaged - as it might if somebody'd tried to break in or force the lock.
It just seems like the lock got "stuck" after being half-turned.

I'll give th lock a spray with WD40 but anybody got any advice for sorting this?
Is it a common issue?


Thirdly, there's the stereo.
Seems a lot like the common fault where everything is apparently working but there's no sound.
The only difference is that all the radio preset buttons DO seem to work.
Is this still likely to be the dead chip inside it or is there something else I should look for?

Anybody know of a good guide to removing the stereo for repair?


That'll do for now, I think.
Any advice would be appreciated.

The classic gearbox bearing noise is a whining noise in lower gears,  turning the steering wheel does not normally make it worse.  The scraping noises from Jazz are discussed in detail on other threads,  could be stuck caliper or rusty disc faces,  or the shield around the brake disc can sometimes warp and touch disc. may help to jack car up and spin the wheels to see if noise is there.

I would not use standard WD40 in any lock,  it dries to a gummy coating that can stick the lock tumblers and it attracts dirt.  Use a good quality PTFE advanced lubricant,  I have used 3in1 ( they are owned by WD40 company nowadays anyway ) on locks with good results, including padlocks that are outdoors in all weathers.

There is some info on forum about the chip, even the make of it and where to buy it from.  If the radio controls and display works the chip may be OK and the speaker plug may have come loose.

Hi

I have had same exact issues as yours here is what I did:

1. Replacemed gearbox flywheel and clutch ( you can find gearbox on ebay with warranty) some might offer replacing  it for you as well in exchange for your old gearbox.

2. Door locks very common issues it started with driver door then passenger door then the i started using the boot .. this was also giving me hard time. So to solve this I bought keyless entery upgrade I wired it under fuse box. I used scotch wire clip to make wiring easier. Now works perfect with the remot. Some people replaced the lock but it won't stop you will have to keep doing that often.

3. Radio was same issue shows fm but no sound so I ordered double din frame from ebay shipped from China and bought 70£ single Sony stereo from Halford with USB and fitted it. You also will need cable to fit that check with them to give you correct cable.

Good luck. If the catalic converter never been stolen I suggest you buying lock to protect it otherwise it may cost you 600£ minimum  to fix it.

Gearbox starts in 1st then as the problem worsens spreads up the gearbox. On a hard lock, you put more pressure on the transmission so it could sound noisier. That was when mine first became noticeable, It won't fail. I found it eventually became embarrassing so I found a specialist to repair it, in situ, for £324 all told.
The radio works as normal, just no sound. However, the CD should still play. I bought the regulator chip for a couple of pounds and if I ever need to remove the radio from the facia, I'll replace it.
My locks are fine, but as culzean says, don't go near them with WD40.
To confirm the brakes are not rubbing, go for a run then coast to a stop somewhere. Feel the wheel centres (BE CAREFUL. ONE OR MORE COULD BE HOT). Warm or hot suggests a brake rubbing.

Thanks for the replies.

FWIW, my guess would be that the noise IS related to the gearbox, but I'm just not sure if it's the common main-bearing fault.

The fact that it doesn't seem to make any noise when I pull away in 2nd made me wonder if it might be, say, the 1st gear synchromesh or something.

Although it sounds a bit like the noise of a dragging brake-pad, I'm pretty sure it's NOT the brakes because it only seems to happen when I'm accelerating (in 1st) and not at any other time.

Course, accelerating from a stop, in 1st gear, IS when the gearbox is under the biggest load so maybe it is the gearbox main bearings and what I'm hearing is the "first stage" of the problem.
Alternatively, I guess, it could the the bearings in the diff', which might explain why it's more obvious when I'm turning the steering wheel.

Bottom line, I'm afraid, is that if it IS a bearing anywhere in the gearbox/diff' I'm probably going to ignore it.
I only paid £150 for the car, as a cheap runaround, and I'm desperately short of money so spending £350 to repair the gearbox just isn't going to happen.

I lost my job at the end of March, I need a car to help me find a new job and I'll only be using the Jazz IF I can find work, at which point I'll be earning enough to replace the Jazz with a better car (or, if I decide it's worth it, repair the gearbox).

Gearbox in the Jazz is pretty much bulletproof, except for the input shaft bearing, so I wouldn't worry about it. Get on, enjoy driving it and good luck with the job search.

[olduser1]

I would live with these issues, concentrate on how long left before the MOT is due. Check the MOT history on govt website tackle any advisories first. Good luck with the Jazz.

[culzean]

If it is the input shaft bearing it starts off getting noisy in 1st gear then as more mile build up is will also affect gear 2, 3 etc.

Will not fail, just gets noisier,  this is due to helical cut gears which are much quieter in mesh than straight cut gear which whine ( like reverse gear or the BTTC and rally cars gearboxes ).  The helical cut does put a thrust on the shaft and into the bearing na d this causes slight pitting of the bearing race ( which is what makes the whining noise ), it is normally cars that do a lot of local stop-start that develop the noise first as the thrust on shaft is more in lower gears when accelerating, my wifes local mileage MK1 got it about 70K,  my main road commuter Jazz ( identical car, year etc, ) still did not whine when  traded it in at 120K (miles )

[degzi]

If its the gearbox I wouldn't worry too much. Mine stated about 85k and I'm on 134k now without much difference in noise level.

1st gear sounds like reverse but the others are quiet unless I'm accelerating hard in 2nd and 3rd then it just whines a bit.
