2004 Toyota Land Cruiser — single clunk over small sharp bumps

OP update: scanned the 2004 Toyota Land Cruiser again and still only have the one pending code, no new lights. If the story changes I'll post the new data.

If it were in my driveway, swap the cheap/easy piece first on the 2004 Toyota Land Cruiser and see if the fault moves. That's the branch I'd chase this week. That's the sequence I'd use. I'll update if anything new shows up.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2004 Toyota Land Cruiser is losing coolant with no puddle. That's the branch I'd chase this week. This is from a 2004 Toyota Land Cruiser in Dallas with 214,000 miles. If they can't show the line item, I assume it's hiding. Not trying to scare you — just skip the expensive first guess. If the story changes I'll post the new data.

It did single clunk over small sharp bumps twice this week, both times after sitting. No change in mileage feel. Doing the boring step first on purpose.

Intermittent stuff lies if you only catch it once. Move a coil or plug on the 2004 Toyota Land Cruiser if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. On “single clunk over small sharp bumps,” that was the fork that mattered for me. Stop there until you know. I keep a notes app thread for this now.

Log the conditions before you spend. Loaded-suspension checks on the 2004 Toyota Land Cruiser catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. On “single clunk over small sharp bumps,” that was the fork that mattered for me. This is from a 2004 Toyota Land Cruiser in Dallas with 214,000 miles. If it doesn't change the out-the-door or the repair estimate, it's noise. This is the filter I use when the thread starts repeating itself. Checking again after work.

I wouldn't throw parts yet. Capture voltage while the 2004 Toyota Land Cruiser is actually failing — after it restarts you've lost the clue. Don't erase codes until someone who can help has seen them. Not gospel, but it saved me a headache. I've seen both outcomes, which is why I'd test instead of assume. Heat soak after errands is the other window.

It did single clunk over small sharp bumps twice this week, both times after sitting. No change in mileage feel. Only after sitting overnight so far.

This is usually cheaper to test than to guess. Get a real battery/charging test on the 2004 Toyota Land Cruiser, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. If it doesn't change the out-the-door or the repair estimate, it's noise. I'd rather look cautious in this thread than stuck later.

Ask what changed right before it started. If a shop can't duplicate it on the 2004 Toyota Land Cruiser, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. This is from a 2004 Toyota Land Cruiser in Dallas with 214,000 miles. Had a similar mess a couple years ago and that's what finally sorted it. I'll update if anything new shows up.

Log the conditions before you spend. Move a coil or plug on the 2004 Toyota Land Cruiser if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. On “single clunk over small sharp bumps,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. I'll poke at it this weekend.
