Hi,

Wondering if any mine can give some advice on a strange issue I am experiencing. I have recently started noticing that when I am driving over 40mph the car is shaking/wobbling. It feels like it is coming from the back but I am really unsure... 

I have in the last month had the brake discs replaced, all 4 wheels balanced to try and correct the issue but nothing seems to be fixing it. 

The model is Ford Focus, 2014 reg and I have only done 33,000 miles in it so far. 

Anyone got any ideas of advice? And yes I have arranged for it to go to a garage to check it but just seeing what others might think.. 

I had a similar issue but seemed to be the front. After replacing both my drive shafts but still having the problem (so obviously they changed without them being the problem) it turned out that one of the wheels had a slight distortion and the tyre had very uneven wear. I got the wheel straitened by a company in Gillingham, Kent (Lepsons, £80) and a new tyre and all the shaking stopped. 

@Seaniepie thank you for your info! What you’re saying about the tyre makes sense as I did have them say when my wheels got balanced that one tyre has very uneven wear on the back. 

I am hoping the wheels don’t have distortion. How did you find out about the distortion of the wheel? Did your local garage pick up on it? And when you say you got the wheel straightened do you mean the alloy or what the wheel bolts on to? 

I went to the garage today. They checked back tyres and both my rear tyres have uneven wear. They have recommended I replace both back tyres when I can. Also they found back drum brakes could be worped. But they said I would only notice that when braking so if I am not feeling it then to ignore that for now and just do tyres.
