Thanks Suddens and welcome to the forum . I am at 172k on my 06 and like you I have replaced quite a few parts . There is still a lot of life left in my 06. I don't have rust issues as I am in South Florida and not near the ocean. If you don't mind post back your airlift install for us to see. RegardsOur 04 LE just passed 275,000 mi (we bought is at 90,000). Plenty of parts replaced in the process - springs, struts,bearings, etc. It has rust that will eventually kill it but still drives smooth.
For our "new" 05 (153,000) I am going to install the AirLift springs to raise the back end a bit and hopefully prolong rear spring life in the process.
Congratulations!I own a 2005 and just hit 854,000 original miles. Still original motor and trans. Still running strong!!
The following were done once unless otherwise noted. All were DIY.With that many miles..what maintenance , parts, repairs have you done and spent $$??

So you've never had to change the timing belt, and why the three transmission fluid changes at 320k?Replaced shocks and struts, tire rod ends, ball joints, water pump, driver side CV half shaft twice(first one leaked after 25k+ miles lifetime warranty), coils and plugs(#6 twice), alternator, water pump, tranny drain and fill once at around 100k and 3 times around 320K. Recently replaced Intake OCV Bank1 because of a P0012 code. Code came up again once after replacement. I used to change oil&filter every 12k after the extended warranty ran out until the last 2 oil changes which I decided to do every 5k now. I don't know what this tells you about how i maintain my Sienna but she runs good. Everything else is original. 🤞
YOU HAD TO MENTION MY LCA, didn't you? All of a sudden, I'm hearing clunkings I didn't hear before you mentioned it. I took pics of the bushings. Please tell me if these need replacement. What symptoms should I be checking for? BTW, not the highest mileage. Check out post# 375. She's up to 850k+. I'm almost halfway there.I am surprised that you haven't replaced the front wheel bearings or lower control arms that most of us have already done, when reaching high miles.. seems seinna punishes most front end parts to being replaced more often the other cars.
keep on trucking that van to million miles, hopefully. your 400k is highest yet here.
No timing belt on mine. It's a 2010. My understanding is, you drain and fill three times and you're basically replacing all the old fluid in the system that's why I did it three times with about 20 min drive in between drain and fill. I also did that because of our road trip last year. Drove 4,600 miles. Farthest we went was the South Rim of the Grand Canyon. I wasn't having any tranny problems then but i figured I needed to. That's also when i replaced all my shocks and struts.So you've never had to change the timing belt, and why the three transmission fluid changes at 320k?
I'll be watching this thread for your half-a-million mile update in the future.
