My 98 LS400 is making a thumping sound from i think the front right wheel when i make a turn to the left at 30-40 mph. There is no thumping when turning right and very little when straight. New tires were put on today, and the thumping is still there. any ideas?

 

front bearings?

 

my mechanic said it would be more of a grinding sound if it was a bearing, however my friend thought it was a bearing when he heard it..... i dont know...thanks!

 

go and look go for play, sounds like it could be anything from UCA Ball joint or bushings, LBJs, wheel bearings, TREs, LCA bushings, etc....
