As my Ka has had like 82k miles put on it, it's not longer feeling as stiff when cornering and steering as it used to, and going around corners slowly in car parks for example results in a small amount of tyre scrubbing and loading up the suspension cornering when driving in a spirited manner doesn't feel linear? As in if I throw the car through corners when the weight transfers it feels like there is some play and then my suspension loads up after. My guess given the mileage is that the bushings are on their way out so I was thinking about just replacing them all around with poly bushes but I wanted to firstly ask whether this sounds like bushings as a culprit (and how I go about checking them) and if it does sound like the bushings are on the way out then how do I go about replacing them, I have read about people using different sized sockets with a nut and bolt on either side and tightening it to force the bushes out or using a press. There is also some noticeable ticking when driving slowly on full lock which I think could be indicative of the CV joints being worn but I'm not 100% sure and again not sure what I'm checking for if I pull back the covers.

Any help would be much appreciated, thank you!

The best way to check bushes is to get a long prybar between the component and something solid then see how much 'give' there is in the bush when you try to lever those two apart.  There should be a tiny amount of movement in the rubber on brand new bushes, but really very little.  If there's a lot of movement, or the rubber has detached from the metal, they need replacing.

Different people prefer different methods for replacement.  personally I prefer a press, but have seen the washer & bolt setup work.

Clicking on full lock usually is a CV joint.  There won't be much to see unless the cover (aka gaiter/boot) is damaged though.  If you pull back the boot and it's full of water, grit or rust then it'll need replacing.  If the boot is still sealed fine, then the ball bearings in the CV joint may have become more oval than round just through normal wear, but that's virtually impossible to see without fully disassembling the joint and degreasing everything.  You can peel back the boot, turn the steering to full lock, and then rotate the wheel slowly by hand to see if you can see the joint 'skipping' at all, though it may not be noticeable without the weight of the car on it.

Okay I'll have a go prying them and then replace, I'm guessing they're all going to be knackered given the age and I'll get a new set of CV joints.

Thank you!
