Does anyone know if this applies to a 2022 is300?

I have a 2021 IS 350 and have not observed the issue yet with about 7,500 miles on the tires. It might be too early to tell. Maybe some 2021 owners with more miles can chime in.

I would say to wait and see for now.

I have a 21 350 with 7200 and no uneven wear. The wear is very even across the tire But did the LCA design get reengineered? I took it to get it inspected and got underneath with the tech and The bushings are clamped between two large pieces of metal. Didn't have time to really analyze beyond that description but I thought it was only attached on one side in previous models and that was mainly why the rubber bushings flexed. This seems like a solid design that would prevent wear but give you a softer road feel from the rubber. I may upgrade to the PU bushings anyway lol just for the increase in feel.

A picture would be much more helpful than words.

I have no idea if you're describing the same piece from before or not.
Did they look like these?

Fair enough. Especially since I was wrong about the design lol. That is the bracket I saw but the sandwiched design is not a thing. Not sure what I thought I saw. Here's a pic.

Any idea why no wear in the new models?

CASeoul

The wear problem is/was fairly widespread but there were also a fair number of owners who never had a problem on stock bushings. It's also affected by driving style- exacerbated might be a better word.

Unless they started using the stiffer rcf/gsf bushings that people use to mitigate the issue? But without more data I don't know if we'd call the problem fixed just yet.

Ho man, hope this post doesnt appear twice. Having issue with wifi here.

Questions ,
i own a 2017 is200 T Rwd f-sport.
As most of you i am having issue with front inner wear.

I was looking for Figs lca 90 duro. LCA with braket.

1- is it possible they are no longer available on the figs website? I had the page saved in my "favorites" but now it says item not found. Im either blind or they dont have them anymore?
2- will the figs be like the RR racing. Meaning will i have to remove them yearly to grease them? ( i drive the car year round in montreal cold and winter elements. )
3- rear tire are still decent. Will easily do another summer. I dont like throwing money away. If im going with the michelin 4s . Only in front for this year. Do you guys think its a bad idea? Would have change the rear ones next summer . ( original turenza in the back )

Daily commuter / no track . Enjoy some sporty ride. Want to reduce inner wear.

you don't need to replace rear and front together. the original turenzas are pretty bad IMO except for being a little quieter

2 - Yes, they will require lubrication.
3 - Just replace according to wear. Since it's RWD the only risk with replacing one axle at a time is rain/snow performance. Generally you'd want the rears to have higher tread in order to ensure drivability (i.e., prevent oversteer in the rain).

ShrinkDoc

Are you saying we should lube the newer bushings? If so, what lube and where?

arentz07

The grease should be included with the bushings if you buy from the manufacturer.

Installed my FIGS almost 3 years ago, and had some squeak on slow hard left turns (e.g. back out of driveway and make a hard left going forward). Finally annoyed me enough that I got a can of silicone spray lubricant and gave both ends of the bushings a soaking (without removing them). No more squeaks and I have been driving the car year round (was intended to just be my winter and bad weather car [Chicago and Wisconsin winters]).

dlreyess

so on the front, all you changed to negate the issue was the OE IS bushings to RCF?

This is what my rears look like, bad inner tire wear. I will be ordering a set of spc camber arms soon. Do you guys set the camber to 0 once you get them installed? Fronts show signs of inner wear but could be a bad alignment my steering wheel doesn’t sit straight. 2017 is300 awd

I asked this last year but maybe there's more info out there now: has this issue been resolved in the 2021/22 versions? I've read of updates to the suspension & handling for the refreshed model, but no details on what exactly was changed.
