Got a 04 GS300 19k miles last week and I have noticed a clunking/thumping noise up front underneath at around 20 - 25 mph. Over 40 mph and under 20 mph I hear nothing. Is this normal? If not, ideas on what the problem is?
Thanks

May not be this problem....but I lost an Anti-rattle (anti-sqeal) clip on a caliper which caused a very annoying rattle/clunk going over bumps. Hit the brakes and it goes away...and I couldnt hear it over 25 mph. just thowing another possible cause out there.
