Agreed. I've had mixed experiences on my old Camry with Moog. OEM was always 100%.

 

Go OEM, this is a steering component.

 

I might just take one for the team and try out Proforged. They seem to do well in the domestic/drag racing community. Hell, Moog used to do well back in the day but have been on the down hill slope the past few years. OEM has always been the tried and true way to go but I believe there is at least another option to go through. You'll never know until you try and unfortunately sometimes it's always on your own dime.

 

Reviving an old thread…I looked up the part numbers listed above for the cotter pins (90468-16017) and 17mm castle nuts (90171-12002), and the Lexus parts website says those parts don’t fit ISFs. Instead, the website is recommending p/n 90468-16039 for the cotter pins and p/n 90178-12017 for the castle nuts.

Can anyone shed some light on which part numbers I should go with? Thank you.

 

Lexuspartsnow shows both of the numbers you posted being correct for an '08 IS F through '14 IS F. Not sure what site you're using, but those numbers still look good from both of my resources.

 

Ah, very strange. I was using parts.longolexus.com.
