Hi guys, I have a '97 Chevy S10 with a manual 4.3 V6, which had a new driveshaft and clutch plate put in last year (apparently). I've only had it 8 months, but in the last few weeks has started making a fairly quiet/subtle crunching kind of sound (sounds like somebody is stirring a bowl full of ball bearings) only when the clutch is depressed at very low speeds, and it is getting harder to get it into gear, particularly 1st and 2nd. When the truck is stationary, it also makes a little donk noise when pushing/letting go of the clutch pedal - whether its in gear or not. I also just remembered that if you're doing say, 40mph, and you try to put it in too high a gear, like 5th, it will make the same kind of 'stirring a bowl of ball bearings' sound, until the revs pick up a bit and the engine is happier in that gear.
At first I thought it could be the gearbox, because the sound is kind of like the sound of two gears meshing loudly, but after a bit of research online it appears that it might be a clutch bearing.
The truck also makes a little donk sound when setting off, in forward and reverse, so also points towards it not being the gearbox, or maybe it does, I dunno, I'm not too knowledgable about the transmission side of engines.
I only use the truck at weekends, and usually only evenings when all garages are shut, so thats when I remember to sort it out, and now I don't particularly want to drive it anywhere with the risk of it going seriously wrong somewhere.
Can anybody tell me what the problem might be, based on my description? The sound is too quiet for me to record on a phone with the engine going and upload for anyone to hear, but if anybody is near me (Putney, SW London), or knows anybody close who could diagnose it, I would be prepared to pay anything up to a few beers. Thanks.
