For the past month, I have had a very annoying squeaking sound coming from the rear of my car. Eventually, after several mechanics and money spent on parts, we found out that the issue was the rear knuckle bushing. After reading many posts regarding this issue, I found this DIY (https://www.clublexus.com/forums/sus...placement.html) however, it is mainly for the GS and not the IS250-IS350. I want to buy the bushing but all of the posts so far do not indicate if the bushings for the GS would fit the IS250 since I cannot find the bushing for the IS. My other alternative would be to buy the entire wheel hub assembly which can be more costly. If you have the aftermarket part number please share it with me. Thanks!

 

Is this it? I know in Australia but maybe will lead you in the right direction

Thanks for the help. I messaged them, hopefully, they can confirm that this is the right part. I don't want to remove the old one and not have the new one fit correctly.

 

You could always try the figs spherical knuckle mount bushings

 

I can see this being a good alternative. I would have to replace both since it comes in a pack of 2. For a daily how do they ride? Has anyone tried these?

 

So, according to this, if you buy a new spindle it comes with all the bushings / spherical bearing in it??

Toyota used these bearings in a lot of vehicles. I sure wish we knew the exact size. Most suppliers sell greased, sealed, spherical bearings for <$25 each...

FWIW: I wrote moog to see if they have a direct application.

Edit: these PN's come up as possible / maybe?
