Intermitent ticking noise

my wife's car is an 02 gp w/ 3.1 v6. recntly the front passenger side has developed an intermitent ticking noise. usually driving at speeds less than 30 mph, straight no turning. brought it to a mechanic he drove it and looked it over said the CV axle and caliper bushings were fine. he thought maybe there was some dirt or ice in the upper bearing plate that might casue the ticking noise. looking for a second opinion, TIA

That was an old thread beyond 3 months old so I moved your post to a new thread. Someone should weigh-in to help you.
