Help Steering Shimmy
 

I have a mech question for you. Bad shimmy side to side at only 55-60mph. But can feel it in fourth through sixth gear. No metal clanking that I can hear.

Have you had the tires balanced recently or rotated?

Had the alignment done, wheels rotated and balanced. I also noticed it shimmer when I apply the brakes hard around those same speeds.

That shimmy is usually an out of balance tire. Since they were just balanced and rotated, I'd give them another rotation and see what happens. If you feel it move then you know it's balance. If it goes away entirely then they may have zipped your lug nuts on without proper torque applied.

The rotor retainers have been removed from the front, correct?

Side to side shimmy - I would also check your track bar bracket to make sure it isn't wallowed out (aka the beginning of death wobble). Check all of your suspension torques just to be safe. Also, I don't know the entirety of your situation but check tie rod ends, drag link ends, etc.

Driver side shock, quick disconnect top bolt were loose. Then the Ball joints are bad too.

I took the axel side TB bolt out and I can't get it to line back up to put the 9/16 bolt in. How do you do this???

Have a friend turn the steering wheel side to side until you see it line up.

Lol, ok well thank you. I'm new to this and I just arrived to Quantico. So hobby shop people will be the friend. Lol

One washer per side of the bolt and do I need to use these?
