Track Rod End - Ball Joint

[SRC-IS]

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.

You have a very early IS250, they weren't released until 11/2005.

The tie rod is attached to the lower ball joint which is only available as a complete unit priced around £80.00 from Lexus.

Part numbers are

43340-39505 LH (passenger side)

43330-39625 RH (driver's side)

You may find companies such as Blueprint do the part or look on eBay, just beware of cheap chinese fake parts.

Here's an example

Lexus seem to have done it differently on this model as the ball joint is normally attached to the track rod end but with this method there are 2 ball joints on the LBJ one for the track rod end and the other for the lower suspension wishbone.

Always good practice to change both sides at the same time.

Thank you both for your advice. Having also spoken to my Lexus-trained independent garage, it seems the part is readily available, but it was just too much for the tyre fitter to do. It'll be changed at the next service if my mechanic agrees that it's necessary.

Thanks again

my 2007 IS250 has the same problem as pointed out by lexus guys during recent service.

they will sort it out as per warranty so booked it in.

looks like a common problem with these then
