subframe shifted?

i've been pulling my f'ing hair out. car won’t drive straight. constant fighting the steering. it's been like 3 months ive replaced damn near everything except sway bar bushings. car has been aligned about 5 times now(different shops/dealer) and all in spec but car is all over the road. control arms, rear motor mount, psmm, tie rods, sway bar links and new tires. honestly don't know when it started just randomly noticed the car pulling then got worse over time. been told it’s just torque steer but definitely happens at all time on and off throttle and favor right side. would TS favor the shorter axle? I purchase whoosh subframe centering kit hopefully after install and alignment it works… anyone have any advice or input?

Most modern cars allow for the subframe to shift a bit because they have extra tolerance. However it should not be shifting often and it should not be shifting easily. After an alignment you should have been fine. I would honestly not think this is a subframe related issue, unless you have some loose hardware.

Whoosh centering kit will rule the subframe out at least. If problems persist, get an alignment somewhere else. Some places are just dumb with certain vehicles. Not surprised one would struggle with a short wheelbase car.

Have you dropped the subframe in the past? The bolts that hold it in are stretch bolts and require some serious torque, 100nm + 240deg from memory.

It wouldn’t hurt to fit the subframe centring kit and replace the bolts, it’s a pretty cheap way of ruling it out.

I'm pretty sure that the alignment specs for the FiST are different from a regular Fiesta. Make sure they're using the right numbers.

Check your tires to see if one or more developed conicity. It happened to my STI and I thought my alignment was off. After some testing. I figured out a tire was fucked up.
