2004 Jeep Wrangler TJ Sahara Project
This is the home base for the HeyDerFolks 2004 Jeep Wrangler TJ Sahara project: the YouTube playlist, the exact 4.0L manual Jeep this build follows, the maintenance parts purchased so far, and the fitment notes I do not want buried in individual video descriptions.
If you are researching a 1997–2006 Jeep Wrangler TJ, the useful part is the repeatable reference: oil capacity, filters, spark plugs, differential service parts, axle notes, and which assumptions only apply to this specific Sahara.
