This wheel bearing replacement How To should be included as it doesn't require a press like the others in your line-up.

Hello there! This list is sooooo helpful! Thank you so much!
One thing though, the auto-to-manual transmission conversion link seems to be redirecting to a gas mileage site? I'm pretty sure that's not right, but would anyone be able to redirect me to a link regarding this how-to? Thanks! :D

Re: 88-91 CRX/EF Civic Frequently Asked Questions (FAQs)
Get yourself the Haynes manual (Chilton sucks for wiring) and a good DMM and make one of the leads about 8 feet long with an alligator clip on it and start chasing wires. It won't take you long to figure it out there's only 2 wires involved.
