I removed mine at 100K and there were no traces of grease in it. I`m pretty sure it had been long gone probably during the break in period and replaced by engine oil. It was still flawless though

The grease seal were intact, so there was no engine oil in the bearing. It spun freely, but it was certainly time to replace it, due to the lack of grease.

So it was running dry? Great that you caught it in time! Out of curiosity, was it a single or dual row bearing?

Single row.

Interesting. Two of the bearings I had a chance to open up were both dual rows, and were filled up with engine oil, at lower mileage than yours. Perhaps the vacuum/pressure that builds up inside the IMS at every warm up cycle can better escape at the single row bearing? Just wondering..

My 99 was the same. Seal was intact. The tech opened it up and it was semi dry ? Dual row.
Anyway piece of mind.
