1998 Lexus LS — driver seat clicks during left-right transitions — trying to narrow this down

1998 Lexus LS 400, about 215,000 miles. I can feel a small click through the seat base in corners. Mounting bolts appear tight and power functions work. How do you isolate rail play versus the frame or motor mechanism?

Log the conditions before you spend. Get a real battery/charging test on the 1998 Lexus LS, not just resting voltage, before blaming a module. Don't erase codes until someone who can help has seen them. On “driver seat clicks during left-right transitions —,” that was the fork that mattered for me. Not gospel, but it saved me a headache. Not driving it hard until I know more.

Not convinced that's the whole story. If a shop can't duplicate it on the 1998 Lexus LS, bring a video plus freeze-frame data, not just a story. That's the branch I'd chase this week. Take it or leave it — that's what I'd do. If this is nothing, great. I want that in data.
