Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

A couple of weeks ago, my driver's side front outer CV boot was cracked and replaced. Right after, I started experiencing some really strange PSM activation behaviour, but only on this particular ramp I take.
The ramp is a sweeper, but oddly enough, I'm not going all that fast on it. The car's attitude is pulling some G as the ramp curves to the left but the ramp isn't really off camber.. The speeds on this ramp is about 50 mph and the PSM kicks in little as the front left (as it feels to me) brake is being activated.
However, i'm not 100% sure, because during the same time, I had rear tires replaced as well. I have about 150 miles on the tires now, and the PSM issue still exists.
I've fine tuned my speed through the corner so only a little activation is felt but I can put my foot down and the car doesn't seem to be worse off by powering through the corner, as I'm usually trying to do.
Can the PSM activation in this particular instance be attributed to the ABS ring on the wheel being 'gummed' up?
I've had these tires before, so i'm not sure they're slipping at all as there are other ramps where I can speed through much more aggressively and not a hint of PSM. Only in this particular highway ramp i'm taking...
You don't mention any out of the ordinary change in tire size which is what those 4 wheel drive cars fight and I'll call semi self destruct on. You also say the other fun spots for cornering don't have problems.
Was the car aligned when you had the rears put on.
No car has not been aligned and the tire sizes are stock. I even changed out for the same brand. The only reason I had to replace the rear tires was because one tire was cut down.
that is my theory, although, I need to take the wheel off and hose the whole thing down with brake cleaner. Don't know if the grease can be diluted by brake cleaner.
