IMS change for next maintenance ?

[thstone]

If you are worried about it to the extent that you're taking measurements only 60 days apart and comparing the data, then I'd suggest that you should replace the IMS bearing as soon as possible.

I have 120,000 miles on my original IMS bearing, track the car 25+ times a year, and never, ever, ever think about my IMS bearing except when I come on this forum and read posts from everyone else.

If you can't forget it, then I suggest that replace it so you can be at peace with the car.
