Toyota Sienna: Fast Vibration And Shaking While Driving

In this video I bring you along the process of tracking down a vibration in a Toyota Sienna AWD minivan. I thought it may be in the driveshaft but come to find out I put a driveshaft in this vehicle about a year ago. Hmmm.... -Enjoy!

Dorman is going to fix the problem. This should be interesting...

[@SouthMainAuto]

Legit man within a week and a half I had a brand new shaft at the shop ship directly from their supplier. And I was blown away at the quality of it and the fact that they use Spicer u-joints in it. I don't know who their supplier is but it looked pretty solid. They paid shipping both ways and the whole deal. I was pretty shocked considering it wasn't their drive shaft to begin with but thoroughly impressed with the quality of the new one. Hopefully they keep that supplier around for a while.

@South Main Auto Repair LLC 4:40 You are correct we don't lubricate those. The supplyer is supposed to. It's always feels weird when you see someone work on a vehicle you used to help build. Just a quick suggestion, If it's 13 though 16 year check the starter. We had an issue with the braided cable arcing onto the fuel line directly below and would melt though it. The fix is a rubber boot over the cable post.

Man that was a good lesson on proper wheel alignment on the hub, I don’t use aftermarket wheels but good info. Thanks for the video I watch all of them.

[@2491kridge]

It really does make a big difference, I have people come in the shop all the time with vibration issues with after market wheels not hub centered and or improper lug nuts. People will get annoyed too when they ask you to install aftermarket wheels and then you tell them they need a whole new set of lug nuts, I’ll work on them if they already have improper nuts, but if I’m going to be installing new wheels I won’t install them without the proper lug nuts because of the liability and potential vibration issues.

[@TonyRule]

Much worse when there's a smaller wheel pilot than the hub spigot and the radiused back edge of the pressed pilot hole in the wheel sits on the outside face of the spigot with the nuts barely engaging any thread on the studs. I've seen that and the car had just passed inspection - literally - drove less than 100ft to get tyres because they were worn - not because the wheels didn't fit the car. I think I still have a photo somewhere. My eyes nearly popped out of my head.

[@chrishayden8137]

I used to work at Napa for years and this happened all the time with suppliers coming and going. One of the most annoying parts of the job. I went and started my own business. Hearing that the issues haven’t changed, I’m glad I left 💀

[@gingerd2098]

You're correct Mr. O! A wheel with a proper sized bore is called "Hub Centric". They are called "Nut Centric" when the center bore is too large and the lug nuts create the clamping force as well as support the weight of the vehicle. You're also bang-on with those Toyota style nuts. When used in this manner on a non-OEM wheel, they are only meant to be temporary like with the included spare tire. It's crazy how many wheels I see come in (even from another one of our stores) and it has the incorrect mounting hardware.

[@charlesdavis9755]

Fun fact if you have a 1970 Chevy Nova SS with original wheels. The original SS steel wheels are lug centric and not hub centric. If you try to balance by the hub, the holes are so far off the the wheels wobble on the balancer. They have to be balanced off of the lugs. I searched and could only find one shop close to home that had a balancer that used the lugs. Everyone uses hub centric balancers since all modern wheels are made hub centric. Special thanks to Joe at Speedway Tire. Also, thanks to you, Eric for another informative video. Keep 'em coming.

[@billrimmer5596]

I think it is really smart that Dorman has the savvy to c 664,000 subscribers to one of the BEST KZbin channels on car repair and then take the initiative to develop a dialog with one of their fiercest critics. I mean u just hammer them every time. We have to use Dorman stuff, and a lot of it works ok. Ever buy a lug nut? The electrical stuff is horrible. But it seems they r watching and listening. If they would just cull their suppliers and switch to the ones that the OEM people use, maybe we could buy a sensor or module that worked longer than a month. And when and if they give u a well greased driveshaft that fits, buy twenty of their lug nuts and put them on that sweet little Sienna. And then tell your 3/4 of a million fans that Dorman isn’t the worst thing since hemorrhoids. I have watched every one of your videos since day one When I did a re stud of a Toyota aluminum four cylinder, I used your Rav Four videos exclusively. The car still runs great. Thank u Eric!!

It’s fairly common for aftermarket wheels to be fitted lug centric instead of hub centric. I had a 05 GTO that I put some aftermarket wheels on and had to use hub rings that were sized to the hub and the wheel. Mine were made of aluminum. I never noticed a problem when I did not have the rings installed. But once I realized the rings were needed, I installed them.

Good vibrations.. 🎶🎶🚗

[@SimpleElectronics]

Good call on the lug nuts Eric - one thing to watch, specially on Honda (and I believe Subarus) is that the OEM is actually a "acorn" which has a spherical seat lug nut and most of the aftermarket wheels we encounter have tapered-conical seats. On steel wheels, it isn't the end of the world - sometimes over-torqueing the lug nuts will "crimp" the steel, but usually it is fine. But on aftermarket alloy wheels, the cheaper ones without the steel inserts for the lug nuts, the spherical lug nuts destroy the soft aluminum tapers. -Just something to note!

[@kain0m]

Yeah the shape of the contact surface is super important, because that is what ensures that your wheels don't fall off. The friction between the nut flange and the wheel is what keeps the nuts from spinning off.

[@keepingdistance4404]

Ball-seat is used by Honda, VW-Audi, and Mercedes. They are rounded. Conical seat is straight. Improper surface contact provides no retainment torque. These Toyota mag-shank lugs (dual purpose) have a conical seat because the spare wheel is steel.

I can attest to the hub centric wheel issue. Had an aftermarket wheel on BMW with a wheel spacer set up on hub that needed a hub centric ring to stop the vibration of the wheel/tire.

[@NoahWL1]

Hub centric rings on my aftermarket stud centric steel wheels made a huge difference for me (even with the correct acorn style lug nuts). $20 from Amazon as a last ditch effort and it worked great. I bought a few different sizes because it was hard to tell exactly what I needed, even with calipers.

[@BruceLyeg]

I've a drawer full of them, some plastic and some aluminum and all different sizes. Now I can shop for used wheels and only have to worry about bolt pattern and offset

[@gingerd2098]

It's not recommended to use them on steel wheels as seen in this video however. For alloy wheels, it absolutely makes a huge difference!

[@G31mR]

i agree. I never put aftermarket wheels on any of my vehicles with the appropriate hub-centric rings. I like to head off trouble before it rears its ugly head. I have used aluminum rings on both steel and aluminum wheels, and the plastic type rings on both steel and aluminum wheels. Never had a problem in the four decades of doing this.

The first driveshaft you bought was a reman, A1C during the pandemic(just about all the A1C remans produced in 2020 to early 2021 are junk doesn't matter what part they are), this was bound to happen. As for NEW complete driveshaft assemblies just about anything for this sienna is either a DORMAN, or if you have money to burn the OE. There's about 4 large 'manufactures' for this driveshaft you'll actually run into but they're all produced by DORMAN.

Even only having months of experience in the field I could tell those wheels wouldn't work very well with those nuts. About half the people who come into my shop have a different set of nuts for the winter wheels, and the rest at least have hub-centric wheels so it doesn't matter as much. But the slack on those would have me writing a bunch on the work order before I handed anything back. haha Also that buzzing would drive me insane. I'd be pulling that door apart in no time if it was my own vehicle doing it. I already ripped the dash apart in my Camry because it buzzes sometimes.

Dorman tale. '08 F150, the HVAC "blend door actuator" failed. (For the record, it is not easy to replace, as it is buried pretty deep in the dash.) Replaced it with a Dorman from The Zone; it stripped its gears at both ends of the temperature range, even after the computer did the "relearn" sweep multiple times. Replaced it under warranty; second one did the same thing. Got hold of Dorman tech support and explained the problem. They said to pull the fuse, wait 30 seconds, plug the fuse back in, and the computer would do the "relearn" sweep, and this would solve the problem. I replied that I had already done that multiple times - with two different copies of the part - and that I just did it again because they asked, and it didn't help. Dorman Guy said "That's strange, that should have worked." And had nothing else to say, and did not reply to any further emails. I returned the second Dorman to The Zone and got the OEM part from RockAuto, and it worked perfectly. Now, as a home gamer, I don't really know how to put a monetary value on my own labor, but I damn-well spent more than $20 in time and frustration replacing that dumb thing three times in an effort to save $20 buying the Dorman part over the OEM.
