Front end work...

[Hallmark]

About 60K miles ago I replaced my thrust arms with Lemforder arms and 750i bushings. I've developed a slight shimmy when I brake and when I corner (but not at highway speeds) and I'm thinking I need to replace the sway bar links and control arms.
Do I need to replace the thrust arm bushings again so soon? Is there anything else I should replace as long as I'm in there?

If it is when you brake how old are your brake rotors, they may be warped

60k miles is about enough to toast a good thrust arm bushing; this is probably your problem.

..just to be sure, the classic question: "Did you tighten them with the suspension in the fully loaded position?"

They're Brembos from BMA. When I brake lightly I get a shimmy, then I push a little harder and the shimmy stops.

If 60K is enough to toast the 750 bushings, how long do the regular bushings last?

i had the same problem and it turned out to be warped rotors. just a suggestion...

check the whole front end before you go replacing stuff, and yes the thrust arms could be toast.

From what I understand; about the same. 60k miles is a pretty damn long time.

One thing to check; make sure your wheels are torqued evenly and to spec. Sometimes uneven wheel torque can cause minor difference in heating/cooling across the rotor and lead to warping. This is notorious for happening after leaving a tire shop that loves their impact guns.

jack the front end up off the ground. Have a friend wiggle the tire left-right as you sit under the front end feeling for anything loose at the joints. Derek checked mine at Nikolas and founs a loose tie rod end, worn sway bar link and the drag link is starting to get there, add it all together and I have a loose front end and the wheels shake when I brake. Could be the toast control arms in addition too.
