Hi,

Thank you for the input

Is this the correct part you are referring to "lower control arm"?

I would recommend getting OEM ones. LCA #2 looks like an S, not like that

Deffinately agree with gs4. Got an outer tie rod from eBay once and it was like an inch longer than OEM. Idk if it makes a difference but I just did trust it so ended up buying oems.

Hi,

Can you please let me know if the shakes go away once your control arms are installed or if there's is at least a big improvement?

Thanks:

Before changing any suspension part, make sure it's bad before changing it. If the suspension has bushing, check to see if they are cracked and use force to wiggle it and see if theres play. If bad, then change.

While I know that it is important to replace any worn suspension parts if they are in need of replacement, I never really solved my 60mph shake until my tires were replaced. I fixed everything else until it was time to replace my tires then I bought a set of Conti ExtremeContact to replace the cheap junk that the seller used so that he could say that the car had "new tires" when he sold it to me. Once the Conti's were installed everything came together like I expected it to. My recommendation is to buy the highest quality tire that you can afford.
If you're not using OEM wheels then my advice might not apply since I keep my cars completely stock.
Good luck!

Could be anything on these suspensions that cause shaking. I just adjusted the damping on my megan ez coilovers for the 1st time and it significantly reduced the shaking. I thought they were set to soft and it turned out they were set to hard!

Hey,

Do you have a tutorial on how to adjust the damper settings?

Much appreciated

I wonder if we all call Lexus the same day and bombard them for a few months straight, maybe we could get a late recall on the suspension seriously the shakes suck! I actually have a paper from a Lexus mechanic saying what to do first and so on and so forth, there's like 5 of them, and supposedly if you do these in this certain order your shakes will be gone for good.... you guys want me to post it here? Or make a new thread? I think it could be very helpful..

This is based on research through Lexus techs, follow the below list in that ORDER:

1) Alignment (very important)
2) Road Force Balance (very important)
3) Wheel Hub Adapters (very important)
4) Replace Ball Joints (recommended)
5) Replace Tie Rods (recommended)
6) Replace engine mounts and transmission mounts (recommended)
7) Replace Caster Bushings (recommended)
8) Replace Wheel Bearings (last precautionary step)

If you follow the above list in that order, I GUARANTEE if you follow that list in ORDER, at some point the shaking will stop.
