Your wisdom, please...!
The car (IS250SE, 2005, FWD, RHD) has recently benefited from four wheel alignment, and feels much better for it. However, the mechanic pointed out that grease is leaking from the ball joint at the end of the track rod (tie rod if you prefer). Now for the problem. His parts supplier lists the track rod but not the component behind the wheel that actually has the ball joint attached. So the questions are: What is this part called (or, what is the part number), and
Is it available from anywhere other than Lexus (unless the dealer price is a bargain)?
Many thanks in advance for your help.
