Hi all,
Just wanted to report back my findings with my newly installed polyurethane bushes on my front thrust arms, or otherwise known as 'front tension strut'.
Just a li'l spill on the situation: I recently changed my front axles and while I was there I thought I'd see how the above OEM bushes were doing. Not doing too well.

I replaced them 12k miles ago and they were beginning to split again, so I decided to go with the polyurethane alternatives.
Well, all I can say is WOW! What a difference!!!! It feels like a new car, the steering is so tight I don't think I've ever been in a car where the steering has felt so solid.

Just feels exactly how you think it should feel!
Light shimmy at speeds: GONE!
Steering wheel wobble when braking or going over small bumps: ERADICATED!
The thought and feeling you have in your mind that 'there's something wrong here-it just doesn't feel right': DISAPPEARED!
To say I'm pleased with the results would be an understatement.
As for the increased harshness of ride/handling people (myself included) might ponder about, let me dispell those thoughts for you right now! I also changed the front AND rear anti-roll bar bushes for polyurethane too, and yes its firmer, but not harsh in any way shape or form.
My verdict: FWIW, I wish I would have replaced the bushes with polyurethane ones MUCH sooner than the 4+ years it has taken
Oh, I almost forgot to mention, these results are
without the necessary wheel alignment-I'll be getting around to it next week. To improve/perfect this further will be some icing on an already extremely impressive cake!
