Polyurethane bushing replacement for the arms: (I have SuperPro bushings). Here’re more cost effective options: Prius Archives - Polyurethane Suspension Bushings
trq sucks! They used to have good parts, but not anymore. I bought some of their hubs. They only lasted a 3 or 4 thousand miles. They replacements, the same, their replacements, the same. Wasting an hour each time to replace them, costly! Waiting for a week for replacement to come, costly! I wanted timkens, but didn't have the money at the time, so I bought moog from autozone. I ahve 75,000 miles on them. It's probably about time to replace them. It's hard to tell if it's the tires or hubs. Sadly, they can't get them anymore. They said the factory is not making them. Which I find hard to believe. I have a year left on the warranty so I will take them back and get my money back if they don't have them by then. And I'll have to find the money for timkens... It's just not worth the wasted time and money buying cheap parts for the suspention. If you don't have the money, that is one thing. You get what you can afford.
