hmm interesting. Steering rack looks nice and clean? No leaks? Steerng pump in good shape?To summarize: the car's steering feels normal when the car is cold, but then it becomes stiffer as the car warms up. Furthermore, after a drive, the steering is noticeably heavy. I've driven this car for some years now and this issue popped up all of a sudden. Just checked the p/s fluid, but it appears to still be a clean bright red.
I was wondering if there's a chance that the variable-assist power steering module (a small electronic component with a quick connector) has gone bad. Is it worth attempting to replace this part? View attachment 145446
