Highspeed steering shimmy/steering wheel play

that is intermittent! it comes and goes.

 

89k miles

 

I have 2 week old summer tires that should be nicely balanced (alignment done also), also a new clutch and new rotors as of last month. Car is 99% but has this annoying steering wheel shimmy around 65mph. sometimes i will take a corner or swtich lanes and it goes away and the wheel feels solid and planted.

 

I have jacked the car and have no wheel play in tie rods, joints, bearings etc. My LCA bushings are prob shot, could these be responsible for this kind of steering play or should i look more towards steering rack bushings?

LCA bushings will definitely cause this if they are worn/torn.

^this. also jack the car ups and see if there is play in the wheel bearings, ball joints, or tie rods just to be sure.

Just throwing this out there but what about a wheel weight that fell off? Inner cv joints ok? I know the inner boots usually rip and leak grease.

^that is also very possible. Maybe even a bent wheel.

Any luck?

Sh*tty tires will cause this too.

Nope no luck. New LCA bushings are in. Feels nice and planted but free play still comes and goes. Thinking steering rack or bushings or something in the linkage not sure

If it comes and goes its an issue involving two of the wheels. When they are in lock-step with each other you get the symptom. I say they aren't balanced properly is all.

now they are like month old tires and nicely balance. It feels more of like loose steering that happens and sometimes ill hit a turn or get on it and it changes to like the nice tight bmw steering feel and no shaking.
