I would like to know this also.
I assume it can but, just how difficult would it be?

Doesn't need to be jacked up, but you will need to support the shock/shock mount just a bit so you can get the bolt through once you remove the one that's there. I used the Yaris' hydro jack to push the shock up just a bit but there are other ways to do it.

Thanks for all the feedback. I think I'd like to stick to the TRD swaybar, but thank you for the offers. I figured you could install it while the car is on the ground, I did the install with my old '85 Grand Prix (solid axle with arms) in the driveway.

$151.20 + tax vs. $134.95 to your door, no tax

#1 upgrade for the $$

Every Yaris should have a rear anti-sway bar. It should be the law. Improved driveability, safety and fun-factor all with no down-side.

"yes"

Okay, I bought the TRD bar from my local dealer, and installed it in my driveway in about 20 minutes. The mounting points are viewable if you look under the rear bumper. A few pointers: First, it's best if you park on a level surface. Then, do not remove the lower shock mount bolts all the way, leave them in with a couple threads of the end sticking out of the lower shock mount. This way you can mock the bar into position and when you get the mounting holes lined up, shove the lower shock bolt home through the hole, and start the nut. Repeat on the opposite side. Once you get the bar hung by the shock bolts on both sides, you can rotate the bar up and slip the bolts through the secondary mounting points. Torque it all down, take it for a ride and you are done!

Like I said, I did it all on the ground in my driveway. The difference in handling was immediately recognizable and this was definitely a worthwhile upgrade. Confidence in sharp, corrective maneuvers is increased, and going around curves is now something quite fun. As others have said, the Yaris should have come this way from the factory. Next step for me is to pump up the air pressure on the tires, this should increase some fuel mileage and stiffen up the ride a bit, too.

not to thread jack, but i'm wondering which I should get-- 19mm or 23mm. i don't plan on getting any wider of tires (195/55 series on 15) and am thinking 23mm might end up as too much

I think I'd recommend the 19mm rear bar, considering you are remaining relatively stock (as I am). The 19mm bar seems to be engineered to complement the stock suspension system and really tightens up the overall handling characteristics of the car. Body roll is slowed (and also limited) to an incremental amount and it's very predictable in turns. I chose the TRD unit but it appears there is also a very reasonably priced aftermarket 19mm rear bar out there (read through this thread). I want to add that my car is equipped with the OEM 15" alloys, and your results may be a bit different with the higher unsprung weight of 15" steelies or smaller 14" steelies.

Don't be timid. I installed mine on the driveway in 20 minutes (including collecting the tools and clean-up afterward. A couple spanners is adequate. A socket set and two spanners even faster. You likely won't even need to lift the car unless you're fat like me.

I didn't even remove the wheels although it would have been slightly easier if I had.
