ive had my astra a few months now and since i bought it tha tc light keeps comin on and cuttin power even if im in 5th doin 50 mph round a slight bend it jus cuts tha power,, and sometimes on a sharp bend tha back brakes grab and tha brake peddle flicks,, i recently noticed tha trackrod arm is bent and front leg is 2,,could it jus be as easy as changin this cos it only happens wen im cornerin wiv tha weight on this side,, cornerin tha other way is fine..
