Contacted KYB support for missing hardware
I bought the same KYB344480 shock absorbers 8 years and 70000 miles ago for an '08 Sienna. I'm now (04/25) starting to detect a chirping from those and some slight hint of abnormal tire wear, so time to refresh. I'm happy enough with the previous pair to buy the same.Last time I bought these, the shocks came with all the washers and rubber parts shown. This time all I received was the top nut. So I contacted KYB customer support via their chat and they sent me the missing hardware (see pic). Maybe I could have re-used the washers etc. from last time -- they looked ok.I would not have said the old ones felt worn, but there is a noticeable improvement in the ride.

Fits 2006 Sienna 8 seats perfectly.
Thanks to all the reviewers above for really useful information. I got these and got them done for my 2006 Sienna LE today. Some of the lessons I learned that might be helpful for others:1. Definitely no need to take the tires off.I got the tip from the other reviewer, i.e no need to take the tire off. There is enough room to work under the minivan. There is really nothing blocking the work.2. Dry run with all your wrenches before actually taking things off.This is to make sure that you have the right tools before taking bolts off, so there is no need to put thing back together and run to shops to get right ones. :-) The most difficult part is to get the bolts on the lower end off, I probably would get an impact wrench had I known how hard it is. All the penetration oil I put over last three days did not get anywhere, based on what I see after I finally got the bolts off.3. The original plastic boots and top nuts are all fine to reuse, I did not use any of the small parts from the package except the shock itself.It took me about an hour and half to get everything done. Ride is clearly better, the original one on the driver side is completely shot. Quotes I got for install them mostly around $500, not bad that all can be done with $100 in parts + 90 minute time.Downside is that I need replace the front struts next.

Super helpful strap
Ty KYB for shipping this with an easy to cut & remove strap. I was able to do this install almost with one arm once I realized that the strap could help prevent me needing to compress the strut for install. Also, I didn't end up using the included bushings, washers or nuts. The original fittings and dust boot were still in good shape so I just reused them. Idk if not including them would have saved me/KYB some $, but it's a thought. Great fit!

Wow what difference
I installed these on my 2006 Toyota Sienna. I had to replace driver side rear shock because it was blown ( 7yrs of service is bad). It was easy enough that the setup took longer to do; than the actual install... Took me 20minutes to install both rear shocks and took me damn near 30minutes of prep... LOL!!!Either way it change the handling characteristic of the van. She seem to ride stiffer than with the stock shocks. The KYB Shocks themselves were aittle longer ( about an inch or 2) than the factor units they replaced. After the install the van felt really good and I could hardly feel the usual bumps and dips on the street I live in ... With these new shocks it seemed to dampened better going down the road.Overall very happy and for the price ... COME ON !!! $68 bucks to change this much of the ride quality ... worth every penny...

2012 Sienna XLE perfect fit, HUGE ride quality improvement
I installed these shocks on my 2012 Toyota Sienna XLE. The van had developed quite a few rattles and bumps that became unbearable. We even considered replacing the vehicle completely. I'm glad we didn't do that, because these shocks drastically improved ride quality and smoothness. I'm actually....shocked.Installation was NBD, took about 2 hours start to finish in my driveway. If you've never worked with jack stands and a good jack, go ahead and have someone professionally do this for you. This is somewhat of a varsity job as once the vehicle is on jack stands, you'll then need to use the jack to bring up each rear axle/wheel assembly individually. Can be intimidating if you've never done that.The original shocks were not even the right model number. SMH. Whoever worked on this van last (we bought it used- it now has 130,000 miles) used the wrong part number, so those shocks never worked as they should. These new ones have completely eliminated any road rattle or annoying bumps.

Only the shock. Not parts shown.
Doesn't come with parts shown, ie., bushings and dust cover.

Difficult to get a matching pair of Shocks.
Ordered 2 and one came in with a different design and part #. Ordered a replacement and it came in with the correct part #, but was designed differently.Units made in Mexico are different design than the ones made in Japan. The compression pressure is different as well.
