Shimmy @40Mph

[spark 0]

I have a 156 that shimmies at between 40 & 45 mph over that speed it's fine until I get to about 80ish when I get the classic out of balance steering shake there is no knocking from suspension bits but they do creak a bit. Is it just a case of the wheels out of balance and the 2 problems are connected or is it a failure of anyone of the suspension bits.

 

Thanks

most likely its just the wheels out of balance but it could be something like a ball joint or bush worn out.

 

Get the wheels balanced first, only costs a tenner or so. If that doesnt fix it, get it up on a ramp and check the steering components for wear.

90% of the time it's a buckled wheel, 9% it's a wheel wieght gone walkies, 1% other (ball joint, nail, CV joints, tyre bulge), personaly I'd jack it up and spin the wheels looking for clean spots where a wieght gone and watch the rin to ensure it's round.

Odd thing happened today i noticed the undertray had come loose at the back on the drivers side and also where it attaches to the wheel arch liner so I got under and cable tied it up and it seems to have cured the wobble a bit. Is it possible for a loose undertray to cause the problem?

Anything is possible, if it'sbeen rubbing the tyre then it'll be scuffed on the inside edge.
