Thanks for the replies yes it needs tracking but I'll wait until I've replaced the top mounts every other bit of the front is only 18 months old(original track rod ends ), no vibration, car pulls left slightly to left under braking, worn section is where minor dent in rim is tyre 3 years old 24k pressure checked about once a month at book pressure of 32psi .
Add to this rear wheels going down due to leaking round the valve stem seals(probably corrosion ) plus possibly out of true front wheel, I'm leaning towards new steel rims and two new tyres, once I've done the top mounts then tracking ( but then do I replace the track rod ends too?) That'll be the entire front suspension replaced complete bar the steering knuckle.
