It was $100 even and with shipping from sewell it ended up being $60 cheaper. Either way it works fine.

I'm sure that any new bushing is a big improvement over your previously worn out bushings!

But members here have reported in the past that there is also a big difference between aftermarket and the real Toyota part, from folks who have experimented with both, on this as well as other "cushioning" type parts, the liquid filled motor mounts, for example.

Default No more shimmy/clunk

I'm not sure what made the biggest improvement, Michelins, strut cushions or alignment.
But what a difference. It really transformed the ride.
These parts with 124k look like they would still have some support left. But I think the cracks indicate lots of movement and loss of control. Things were knocking up front.


These units from Sewell went on my '98 LS400


So $$$$ later, I have new Michelin Primacy MXV4 (H rated) tires and a nice riding front end again. Not cheap, but it was all done for me and I drove away with it. These tires were rated tops by CR recently by the way. They are pretty quiet.

Default Clunks and vibration

Purchased a beautiful '98 LS400 a few months ago. I have had the front end clunks, waywardness on the highway, tramlining, and vibrations over 70 mph. Based on the forum conversations, I had the strut bushings replaced hoping it would address most of the issues but really have had no improvement. Worked the low mileage tires to try to smooth the ride but no improvement. I blamed the tires and bought new Michelins. Same vibration. Rebalanced tires , rotated, road force balanced-replaced one tire of four - still the same. Nothing obviously loose underneath the car. It steers and drives great up until 70+. Any suggestions for next steps? Thanks, Ed

Hey, you taught me a new term. Tramlining. And my car even has this tramlining problem. But my problem is due to rack ends, tie rod ends and possibly LBJs.

But your vibration is probably something else. The cushions fixed my wobble at high speed.
Not sure what may be causing your issue. Are your wheels round?

Default Vibration/Clunk

I've worked through two sets of new tires with no change to the vibration. Rotation, road force balance, etc. My thought is to use a 5th tire and wheel and replace each tire one at a time.

How many miles on car? There are other suspension bushings that also wear and can be causing this. Ball joints in the upper control arm, lower ball joints and rack-tie rod ends. Rear has a similar amount of parts too.

The older and more miles, the more likely the bushings are worn-cracked and in need of being replaced. Not all of them will be obvious to spot. Once out it is more obvious but the hunt can be $. If you have a fresh accurate alignment, inspecting for odd tire wear will show up pretty quickly. If the tech was good, he'd notice the settings change as it is torqued up and would tell you there are worn suspension parts that inhibit him for getting a good setting dialed in.

Default Vibration/Clunk

The car has 64K miles. I'm sure you're right that some other suspension component(s) are bad. Two mechanics that looked at it - one that replaced the strut rod bushings and the other that aligned it didn't see anything amiss.

you cannot "SEE" the issues most of the time. so if they just did a visual inspection, aside from being completely blown out, they are not likely to ever see anything. Need to get out a big pry bar and manually check the condition of the bushings.

same thing for the other parts. the UCA can cause a clunk with little to no play showing in the shake test, you need to clamp-test the joints to see the problem.
