Hi everyone:
This week I replaced the single row OEM IMSB in my 01S with the IMS Solution. The OEM bearing looked like it was brand new. It spun freely and, most important, there was no wobble whatsoever. See the first picture (it looked even better to the eye).
Here's why I'm asking. I removed the seal. The cages looked great and I didn't notice any metal flaking or debris. Also, there was no metal in the filter or the sump. But, because I've never seen the inside of the bearing, I don't know whether the grease had washed out. If I had to guess, I'd say yes.
If my guess is right, my theory is that seals would have limited the amount of oil reaching the ball bearings. As such, it would only be a matter of time before the OEM bearing failed.
What are your thoughts?
Thanks
