Clicking noise after car warms up from wheel area?

Have a bit of a puzzle here. When driving a 355 Berlinetta cold the car emits no unusual noise. But after about 10-15 minutes a noise can be heard, sounds like a clicking noise as though something on wheel is hitting something every time it goes around. I even turned the car off and coasted and still heard this noise. Yet when I jack the car up and rotate the wheel I can't hear any noise nor see where the clicking might be coming from. The strangest part is that it only happens when hot so that if it was an interference issue I would think it would happen hot or cold. I've tried wiggling the wheels to see if there is play in the wheel bearings but they seem tight. Any thoughts?

 

Thank you for the suggestion. Yes, checked that and not a handbrake issue.

 

Thank you for the suggestion. Yes, but its a real clunk of a noise

 

Thanks for the suggestions, some I was thinking. First thing I checked where the lug bolts but they are all snug.
The odd thing is re wheel bearings and CV joints is the noise is not there until the car warms up.

Have you ever heard of wheel bearings being fine when cold and then loud clunk when cold? I was theorizing maybe the grease thins when cold but just theory. Has anyone see this happen before where a noise is not present in a CV or wheel bearing but then becomes very apparent when the car is warmed up?

 

I guess that would be a eureka! what did you do? Have yours rebuilt? Just one side or both?


A CV Joint is like wheel bearings to a degree so I wonder if it might also be the wheel bearings? But as they are tight I suppose more likely the CV joint?

I wonder why they are quiet when cold and so noisy when warm?

 

Did you take them apart originally simply to replace the boot(s)?
Have you found a good source for the CV joints?

So odd that only happens when warmed up. I will have to see if loading changes.
