MKII MR2 Rear Tie Rod Bearing - Hub Side
[Rear Tie Rod Bearing]

If you're rolling with your original bearings, replace them! It's not hard (there's a good how-to video on YouTube). I had a persistent clunking from the rear end that came when going over bumps or when turning at slow speeds. I replaced these, the clunking vanished, and the rear end feels tighter and more planted. I had 160k miles and my originals were SHOT. Yours probably are too!
