Fixing the IMS Bearing - or not?

[kk2002s]

You just have to decide to do it or not. You probably aren't going to get any signs that its time to change. If you do, its most likely to late
Your car being at only 52k miles, you still have a lot of miles left in her. It makes sense to do it sooner than later. The value of the car will also get a positive.
Clean Filter, clean sump and timing still on are positives of good health but if you find metal in the filter and sump it's most likely to late to just make the change without cleaning debris.
IMSB has to be changed before the original starts letting go

Treating as a Preventive maintenance item is the best way to think of it. For those of us with clutches, we tend to tie the two together. Problem here is if your not abusive to your clutch, one maybe looking at 100K + miles before replacing that.
