5th gen rear upper wishbones on 4th gen with 4ws

Thanks Scott - Im probably overthinking things
just so many systems on this lude and possibility that warning bulbs have been removed by prev owner.

So back to basics - notchy feeling from cold could be 4ws but also could be front cv joint so will check that first.
4ws issue could be dry solder joints. Although ive not felt any issue with 4ws when on the road.
Ive also been getting confused about dials - thinking about it - its the srs warning light that is not on replacement dials.

Like I say too many systems tcs/4ws/srs/abs
I wish i still had my BB4 which had none of the above

Today I swapped out the 4ws ecu and refitted the 4ws warning bulb in the speedo - started the car up and the 4ws warning light went out so that is a good result so far. I just need to run the car for a few more miles and see if the 4ws light comes back on and also check to see if the TCS code reappears.
The notchy/pulsing feeling from the power steering still persists but cant feel it once the car is moving so will have to read up on that.
