Maintenance for certainparts

[woodsman]

Then there's the 'since you're in there' category: oil fill tube when doing AOS or coolant reservoir, wheel bearings when replacing struts etc. The idea is to save labour but only applies if you're doing things yourself ( mechanics usually charge 'book time' even though there are shared steps for some repairs).

The most overlooked and important part to change out even though you're not told to, is the single row IMS bearing. The double rows do crater, but not as often. The single row IMS bearings are quite likely to be the part that defines the life of your engine. If you own a single row, do yourself a favor and have it replaced with an open ceramic at a minimum. I bought a 120K mile roller with, you guessed it, a failed IMSB. I've done quite a bit of research on the IMSB, and from what I have learned I'll be servicing mine just like old Honda timing belts were changed. If this bearing fails, you'll need a new engine.
