G60Dan 0 Posted March 22, 2004 Help! It happened again. A weird knocking rumbling noise coming from somewhere in the vicinity of the drivers side front centre of my the car. It sounds like something rumbling underneath the car, as if it's about to come off, but only happens after I've gone hard through a left hand bend,lasts for a couple of minutes(sometimes very loudly)and then disappears again,sometimes never heard of again for a few weeks. I've had my wheel bearings checked and they are all spot on, all my front bushes (anti roll bar & top mounts have all been changed) a CV joint also. I have seen someone on the board with a similar problem, be he didn't say how he cured it - something to do with a driveshaft bush???. Could someone elaborate on this please? Also I put the car in the garage a few weeks ago to get the wheel bearings checked cos I thought it was that, that was the problem; and after saying they were all fine they said about the driveshaft bush. His advise was, get used to the noise (as it wasn't 2 bad then & only happened every now & then) & if it gets worse bring it back. But it's the knocking/rumbling I'm worried about. It's not affecting the braking, and the car still seems to corner as b4?? Any help appreciated. I need to cure it ASAP so I can put the car up forsale officially!! Please help!!

G60Dan 0 Posted March 23, 2004 Also, I haven't actually been under the car myself, so don't know where the bush actually is. Anyone got a picture? Cheers Dan Quote Share this post Link to post Share on other sites

G60Dan 0 Posted March 25, 2004 I took it out last night, I think what ever the problem is, it's trying to reveal it's self. It seems to be getting a bit of a wobble coming from the driver side (front) - but the knocking/rumbling in't happening, it's only actually happened twice ever?? The cars braking fine, no problems there. Wheels have been balanced when the new tyres went on the other month. I'm thinking problem area could be driveshaft/cv joint? Anyone else care to have a stab at it? Quote Share this post Link to post Share on other sites

Anyone else care to have a stab at it? Sounds like a driveshaft problem alright. Could well be that rubber counterweight that col_wan was talking about. If you can get under the car have a look at that and if it seems loose just cut it off. Quote Share this post Link to post Share on other sites
G60Dan 0 Posted March 25, 2004 by cutting this off, will it not unbalance the driveshaft at all? Quote Share this post Link to post Share on other sites
Geo 0 Posted March 25, 2004 by cutting this off, will it not unbalance the driveshaft at all? Well if it's there it's there for a reason but if it's loose and moving around the place then it's really upsetting the balance of the shaft so what I'd do is take it off and see it that makes a difference. It definitely won't make it worse anyway. On the other hand if it seems to be tight on the shaft then leave it alone. Quote Share this post Link to post Share on other sites

Blown 0 Posted March 25, 2004 Twas me who had the same problem. Found the damper loose and just knocking around on the drive shaft so as a temporary measure,I jammed it up against the engine block-seemed to cure the problem-until it works loose again,of course. :roll: As I have the car up om stands anyway,I'll have to get the grinder out and cut it off.

G60Dan 0 Posted March 29, 2004 Thanks lads Problem now solved. Took it in the garage at the weekend so I could get a proper look under it. The bush on the driveshaft was as loose as you like - I could run it up & down the driveshaft!! :shock: Anyway, I gave the guy a drink & he cut it off for me. Car seems fine now. I'm not used to all this non broken car malarkey! Feels wired :wink: I gave it a bit of a shoeing last night, is so nice to be able to do that again! :D Quote Share this post Link to post Share on other sites
