Hi I've noticed recently that when I brake hard , on pulling away after I get a knock or clunk from the rear left hand side . I've had a look around for loose items in the boot and any play I links etc but nothing obvious . Any ideas as to possible causes . It's a 2004 s type r . Also just had new shocks and springs
Thanks
Thanks

Not sure what to suggest next. Maybe jack up that corner and give the wheel a good shake. If good, remove the wheel and give everything a good visual inspection.
Suspension noises can be tricky to diagnose. When you unload the suspension like that, the geometry changes, the spring and shock go full extension, etc. You're not really able to duplicate the fault conditions, such as weight on wheels, applying torque, etc. Sometimes the best you can do is look for evidence of worn parts, such as dusty residue from a rubber bushing, and things like that.
One other thought: What are your repair capabilities if you do find a problem, such as a failed bushing? Depending on exactly what has failed, you may need a spring compressor, big impact gun, etc. It's free to look things over, but keep in mind you may still end up having to take the car to a shop anyways.

Well after a lot of investigation I've finally found the culprit. I had initially dismissed this as being the issue as I had not long replaced the rear lower arm but it turns out to be the 2 smaller bushings in the arm . The part I had used was a refurbished part so lesson learnt only use the original or lemforder (zf ) parts . But all sorted now so thanks for the advice guys
