325.00 for 2 front "Strut Kits" "RockAuto KYB struts
150.00 to install... 75.00 Each

475.00 Plus or minus...... should be a fair estimate.

I put Monroe's on mine about 6 months ago, they ride nice . Drives tighter and more stable at highway speeds .Parts Geek for about 100.00 apiece

Thanks Barry2522.

I just found a pair of Toyota OEM rear struts for my RX on Ebay. I was going to go with Monroe's rather than KYB due to the stiff ride but the deal I found on Ebay was too good to pass up.

Anyone who has done this have trouble with the sway bar links? I see the link attaches to the rear strut and am worried I may have to cut off and replace if the corrosion is bad enough. Hoping a little heat and air tools will do the trick, but I'm not optimistic.

For several days prior to doing the job, I sprayed with PB blaster. Used air tools and had no issue whatsoever. And, this was on a 2005 Michigan (salt!) vehicle.

Thank you. I will do that for a couple days prior. It's a allen key bolt surrounded by a nut correct? At least on the RX's cousin, the highlander, it is. Never seen a nut like that before.

It's actually a torx bit T-30 I believe. An allen key "may" work.

Just changed my rear struts tonight and figured I'd share my experience in case others are planning to do this in the future. Ordered KYB replacement parts (all from tire rack as listed earlier in this thread), OEM coil springs, and replacement bolts for the sway bar link from Lexus directly. I had a mechanic assemble the struts and coils together, since I didn't really want to risk using a spring compressor.

Anyway, to the install. The car is a 2004, has 240,000 miles, and lives in Maine. Everything was totally rusted out and all I can say is thank god for air tools. The bolts holding the strut to the knuckle were, as expected, extremely tight and having an air impact wrench makes all the difference. It was not seized on so I'm positive it could have been done with hand tools. However, I ran into two problems through the process.

First problem was the sway bar link nut. It is an allen key surrounded by a 14mm nut. After 11 cold winters of salt, the allen key completely stripped and rusted out, no chance of having that work out. Had to heat with a torch, hold the back of the sway link (behind the strut mount) and go to town on the nut with the impact wrench. This was the only way I could get it off and was glad I picked up replacement bolts. Reinstall was the same process. Hold the sway link from behind the strut with pliers, tighten the nut with impact wrench.

Second problem (not really a problem, but) was aligning the knuckle with the strut. Had to use a combination of screw drivers to pry the strut into position while hammering down on the knuckle to get it to sit properly. Not the hardest thing to do, just takes patience and fiddling to fit it into place.

All in all, I do think this is doable for the average DIYer. Southern cars will be much easier to do this as dealing with rust and seized bolts was the most difficult part. In the end, it's only 7 bolts and the strut drops out.

Check out this youtube video I used as a reference. It is done on a highlander, which is essentially identical to the RX330.


I hope this helps someone who wishes to tackle this project. I'm happy I did! Good luck!

I like them. As far as I know, KYB is OEM so the ride quality is pretty good. The car feels much more confident driving down the road.

The car bounced like it was on hydraulics or something before the swap . Struts were totally shot.

For people who did the DIY on the struts, how were you able to torque the axle back to the right torque spec? My 1/2 inch craftsman torque wrench only goes up to 130 ft lbs, and i believe that nut is rated around 180ish. just torque it to 120 on my torque wrench, then wing it even more with a huge breaker bar?

You mean the two bolts to attach the strut to the knuckle? I had access to an air gun and just gunned them down as tight as it would go. Seemed to work pretty well! They are pretty heavy duty bolts so I'd give it hell with the breaker bar until they are very tight.

is this part essential for the fronts?? Fr Mount (x2) - SM5423

Tirerack doesn't seem to carry this part. Are the front mounts from the stock reusable? is it a wear item that should definitely be repalced?
