Front metal clanking noise going over bumps.

Front metal clanking noise going over bumps.
Frequently I notice that my car makes a metal to metal clanking noise going over bumpy roads.. which I believe is coming from the front passenger side but possibly both sides in the front... Is this an indication of bad struts or the strut mounts? I've done the press down test and really does not seem very bad.. little to no bouncing and if I turn the radio up and just tune the noise out the car drives fine, the noise itself is the troublesome part. The dust boots are chewed away so I can see shiny chrome struts, not sure if that makes a huge difference. Also the steering seems very stiff.. I have always been a one handed driver and this car has me using two hands at times (I have a v8 mercedes sedan rwd which is really my only car I can compare this to driving wise and that is much easier to steer), I am not sure if this is just simply how the fwd version of this vehicle drives or if this is suspension or power steering related.. if it was power steering would I see a light on the dash? Most of these fluids were flushed recently so everything is topped off and the fluid looks clean.. also no leaks.

Have a suspension shop examine the front end.

One needs long levers and lift [lift with option to load and unload suspension], so it is best to take it to a shop. Pay them for diagnosis [typically they do the suspension checkup for free, in hope to get business].
In my case, my lower control arms were shot. Is that your problem? Maybe!

There are so many reason why one gets metal to metal impact noise.

When folks replace worn suspension with new suspension, they notice the abrupt change [hopefully for the better]. Then there is a long curve down to worn suspension and the change is not observable day to day.
Folks who replaced them, surely are noticing the difference, but I would really wait for a long term evaluation.

If it is front wheel drive the pull to one side is prevalent because of the torque to the drive shafts is different on each side a little because one shaft is longer than the other under hard acceleration. just the nature of front wheel drive vehicles.

Yes it is fwd but the problem just appeared a few months ago. I was thinking I did not tiighten up the power steering belt enough when I replaced it, but I'm not sure if pulling could be a logical result if that. So maybe bad struts?

I did have some play in the steering and some strange steering at times but not really any pulling though but it could be suspension related for you as we both have fwd cars. I thought my issue may have been power steering related but they assured me it was the shocks.

Personally, I lack the data on how good/bad the quick struts are. You will have to make the pick. You need spring compressors [can be loaned from auto part stores]. Understand the risk of compressing the springs. Folks use power tools against the safety with very little concern.
If you decide to do the work yourself .. understand the procedure .. some fasteners have to be loosened before you lift the vehicle and most have to be torqued with the wheels on the ground [suspension loaded].
The good thing that RX is high enough from ground.

Not sure where I posted the procedure .. most likely in SC400 forum [SC folks do lot more wrenching so please read there too... the process is the same/similar]

I believe I know which post you are talking about as I commented on it as well, it sounds like this user recently put these on but that is what inspired me to look into the quick strut route.

Forgot to mention the most common mistake even done by pros ,,,,
Decapitating wheel rotation sensor. Just remove it and keep it out of the way.
