Peugeot 306 violent shake on acceleration
in [Car Maintenance]

From: marpate1 on 30 May 2010 12:33 Hi all, Wonder if you could offer me a little advice? My 306 estate (1.9TD 1997) has a violent shake at around 40-50mph. To try and fix it, I have had all wheels balanced and have just changed both front wishbones as the rear bushes were worn - this has made little difference. I did notice when on axle stands, in 5th at tickover that the near side tyre seems to shimmy side to side. There's no play at all in the bearings or ball joints and the spare does the same. Any ideas why this could be and whether this is likely to be the cause of the shake? And advice gratefully received! Kind regards, Mark

I will take a look at the driveshafts tomorrow when I repeat the test - is there anything that can be testing statically (play in the CV etc)? Cheers, Mark

You could well be right that it's an optical illusion. I'm tempted to get a dial gauge to check anyway (unless there's a method to do this without one). Cheers, Mark |
