Hey fiestaST peeps need some help. I’ve been experiencing slight vibrations/wobble while driving mostly feeling on steering wheel and slightly through chassis. It can be felt slowing down,speeding up and applying brakes.I’ve replaced all wheels with a balance and 3x alignments . Along with the front 2 struts with brake and rotor set. Inner outer tie rods replaced , control arms and wheel hub assembly. Taking it to three different shops and unable to pin point the issue. I’ve been leaning towards CV axles or Motor Mounts for next repair.

Ugh - been dealing with a similar issue that shows up at 80+ mph. Tightening end links to the sway bay to spec and the ball joint helped, but didn’t illuminate the problem.

Are you running an after market rear motor mount by any chance? That may transmit more NVH to the other motor mounts cause issues.

Does it happen at certain speeds, or fairly consistently?

CV joints good?

I’m certain there good. Had 3 different mechanics look at them. From what I’m seeing looks it’s all good no grease or tears. Taking it Wednesday to a different mechanic to see if they can inspect mainly mounts or axles.

Does it matter if you push the clutch in and coast v. being under load at highway speeds? Might help diagnose motor mount issue…

Did you ever find the issue?

No unfortunately. Recently just installed some swift springs and replaced control arms and CVs, new rim, tires. The issue seems more pronounced after the springs. Can see the steering wobble a bit back and forth when just casually driving. Last thing I’m doing before I lose interest. Tighting the steering rack and realigning the subframe.
