Default Lexus RX 300 2001 78,000 Miles

I've had the struts and tires replaced and still have a rough ride. What can I do to get a smooth ride?

Did you replace the strut mounts, also? Bear in mind, its a 15 year old car and more factors determine ride quality at that age than just struts and tires.

This year of model doesn't drive smooth like the modern ones do. Whether it's due to build or age, that's just how it is.

As far as I can tell, if you want a smooth ride you need to look at a newer or different model.

On a side note, you can try replacing your sway bar links. That's what I'm about to do this weekend. I'm hoping it eliminates the clunky noises I'm hearing and also smooths the ride out a bit. We'll see.

Quite the opposite in fact.

The newer models have larger rims, and in general a stiffer suspension as Lexus seeks to decrease the average age of their customer base (i.e. aiming at a younger audience).

Even the 2nd generation RX rode a bit stiffer and rougher than the 1st gen RX, that doesn't mean that the 2nd&3rd gen aren't more refined though. I haven't had any seat time with the 4th gen yet, so will reserve my comments.

The reason ride quality suffers after all of these years has to do with all of the rubber bushings. Unfortunately, it doesn't make any financial sense to replace all of those bushings as all of the labor and parts involved likely exceed the value of the car.

+1. My 02 RX rides very smooth and cushy over bumps compared to my 2010 RX350. The 3rd gen's suspension is much tighter.

The tires are Discovery Cooper and the struts are FCS Auto. From what I understand the mounts are part of the struts.

Wrong. The mounts are separate, and if you didn't use OE mounts when you replaced the struts, that may be part of your problem.

It appears he bought a quick strut assembly. I wouldn't be surprised if the struts themselves are the cause of the poor ride.

Would have been better to get Monroes or even KYBs with OE mounts.

All the Discovery Coopers appear to be all terrain tires. Something less aggressive would smooth out your ride.

I have driven the Gen 3s. They were nicer for me. Perhaps I've only driven ****ty Gen 1s then?
