twingo gt noisy gearbox.

[oscar]

it could be anything dude, the best thing is to give that a try tomorrow. you can rule the diff out, if the diff was humped or on it's way out you'd hear it straight away. listen in on the gearbox too so you can identify the usual noise of gears turning (this will be a very similar noise to the diff turning) if you don't notice the noises then you at least know it's not going to be major money.

personally i'd suspect the input shaft bearing or pilot bearing, this is something any decent mechanic would pick up. the noise will gradually vannish when clutch is depressed if so. if the diff was on it's way out, when you cornered the noise would get a lot louder as load is applied to the planetary gears. if it turns out to be the pilot bearing of input shaft bearing, the garage that done your clutch will have hell to pay. have a second oppinion

OK cheers once again. Gearboxes are black art to me.

Right I've had the car up had a listen to the diff/box the noise is present all over (I'm even more sure it sounds like a bearing now although I'm unsure what it would sound if the diff was buggered) the noise got louder towards and on the black steel casing closest to the passenger arch. Any ideas??

the black metal casing on the end of the box, as seen here?

that's your 5th gear housing cover mate. see where the holes are, where the driveshaft goes into? this is where your differential sits. it's beside it, but not directly apart of it. here is some more information that i've just put together for you!

every part you see below is available to buy from any renault, and any transmission rebuild specialists can sort this out for you. in all my time, i've never seen a differential end up buggered unless it was on a motorsport build with high torque going through it which would end up with a different situation altogether! i can guarantee the diff is fine, there will no doubt be an internal bearing somewhere or something of the sorts that is getting noisy

i understand you're at your wits end, but even high mileage twingos hold their value very well. a 57k one at your mileage is easily worth 2.5 grand, could be a good idea to trade it in but it could also be just as worth while to run it out a little while longer and get the transmission rebuilt . another 100k + miles if you do trade it in, just don't by a pug or you'll be in a world of debt and trouble fixing it every week when it breaks down

Yeah that seemed to be the source of the noise but like i said it just seemed louder there maybe the steel is just a better conductor of sound? Is there any sort of manual available on disassembly? I've watch a few YouTube videos non of the twingo. I'm weighing up my options may buy an old smoker to get me around for the time being and replace the bearings in the box or get it reconditioned? Is it worth trying to get the garage to own up? I can't see them being keen tbh

my workshop manual eddie, have a browse through the transmission section. it will tell you everything you need to know. yours is the JH3 transmission, you'll see codes at the top left of each page correlating to which engine or transmission the section is relating to. in all the other sections like engine and peripherals, your engine code will be the d4f 780 for the twingo gt.

personally, i suggest if you have basic socket sets and a torque wrench you get underneath and remove the gearbox £0 £0 £0 £0 £0 £0, get a cheap run around for now for a few months and then send the transmission away to be rebuilt (check out the agency transmissions, they are the best in the uk!). kiss goodbye to ever having to change a bloody gearbox again man working on cars is easy, it's just time consuming which puts a lot of people off.

sorry for another long essay, but you did tell them to just change the clutch and it appears they done as instructed although i wouldn't defend another garage, we aren't members of the masonic lodge!!!!!!!!!!! i would say however, that if you were to take the car to me .. i'd never take your word that the clutch was shot, i would always make my own diagnosis first before commencing with the clutch replacement. the issue is that there are not many proper mechanics left, dudes aren't taught to repair anymore .. they are just taught to change parts. change this, change that .... how about you bloody fix the part? i've seen folk replacing entire starter motors because it needed one shim washer internally (at a cost of 3 pence......)

Yeah unfortunately I think you're right on the garage front . I'll have to see what's available in the area for part ex could do with an estate/van for work so that's probably what I'm going to do. Thanks once again.
