I've installed Whiteline bushing sets on a ton of Subarus, but never on a Toyota. So naturally I had no experience in doing the job or what to expect as the end result. You can purchase these bushings from many different sources and expect to pay around $130 total for the SMALL and LARGE set. The differences are obvious right away, the rear bushing has a lot less soft material while still leaving an opening for flex. Both bushings have reduced the bolt hole in the middle to the smallest possible size, and this is probably the major reason for buying these.
This install requires the removal of the lower control arms, a press, and some patience. The Yaris ball-joint stud is hidden under the axles, so a standard removal tool will not work. I remove the lock-pin and castle nut, then pry apart the hub and control arm while hitting the hub with a hammer. Once it separates, remove the two bushing bolts and then the arm is free.
Now you need to mark the control arm where the openings line up in the big rear bushing, so that the new bushing gets pressed in the same way. The small front bushing is the hard part, there is no way to get this part of the arm into a press so you need to get some big sockets and a long bolt like this:
Once you get the original small bushing out, then apply the provided lube to the contact surfaces and push in the new Whiteline parts. Now your control arms will be ready for installation.
Installing the arms back onto the car is where it got tough for me. This kit comes with 4 locating washers for the rear bushings, and they leave no room for subframe misalignment. I had to loosen all of the subframe bolts and re-center it to get the rear bushing bolts to go back in. The rest of the install is easy, but be sure to get an alignment after.
This is where I noticed a big difference. Before installing these bushings my car always had more caster on one side, then after the bushing kit install my caster matched EXACTLY on both sides. Thats really the only thing I noticed, the car didn't feel any more harsh and it hasn't made a single noise in the 2 years Ive had them. I inspect these bushings all the time and there are no tears or deformities yet, Im very impressed with these bushings and I definitely recommend them for street and track.
