150k miles 2.0l gas mkIV Jetta, 5-speed manual.
Braking at speeds of around 40mph down to 20mph there is shake in steering and overall jerky stopping. If slight steering is added(say gentle off-ramp-turn) fairly loud wobbling(best I can describe, pretty much whole car shakes) can be heard and felt. I'm also hearing a clunk noise from the front when car weight is shifted during a 90degree turn. This is guaranteed to happen when pulling into a drive-way with a gutter.
Front brake rotors changed less than two years ago(maybe 15k miles), alas the pads were almost brand-new and weren't changed at the same time. This solved a very similar vibration in steering wheel when braking, I assumed previous rotors were warped. Tires are brand new.
I could assume that the new rotors are already warped and change those again along with pads. What is bothering me is the steering input multiplying the issue to such a great extent.
I must add that in the past few months the ABS light has been coming on only after reaching 20mph. Light is not on after starting the car.
All the suspension is factory. 12years old(I know right)
My personal vehicle maintenance experience only includes simple jobs: brakes, oil changes, coolant flange, any work that doesn't require specialized knowledge/tools.
Bushings? Mounts? Control arms? Master cylinder? Wheel speed sensor? Where should I start?
