In this video I break down everything I’d personally look for when buying a Lexus GX470, based on what I found after picking up my 2004 GX with about 100k miles. These trucks are old now, and they’ve got some common pain points, so I walk through the stuff that actually matters—like whether the timing belt service was done (every ~90k), why I always pull a Carfax, and why I still change the oil immediately even if the records say it was just done. I also show you what I check underneath: frame condition (and how to tell surface rust from real rot), leaks vs a normal little “weep,” and CV boots up front. I also hit a few GX-specific things that can save you a headache: the rear air suspension (sagging airbags and how coil conversions/lifts fix it), the non-nav vs nav interior debate (and why people want non-nav), and the common interior issues like seat wear and dash cracks. Then I show you how to verify the center diff lock actually engages, plus a few “real life” quirks on mine—like tire rub at full lock, small cosmetic damage I’m not fixing, and the maintenance I’m planning next (diffs/transfer case fluids and a brake bleed).
