Hello all. Do to the great advice and resources of this forum, I successfully replaced the bearing in my air pump today. Total cost: about $25. Total savings: about $600 if I bought from dealer

The car was my 95 E320. Total time, about an hour and a half, start to finish. I took the airbox out, radiator shroud, and plastic mechanical fan. That gives you alot of clearance to get to all the bolts.

I bought the bearing from bearingsdirect.com, part number: 32BG05S18G-2DS

Below are some pics. Very simple install. Would recommend a small press to get the old bearing out.
