The assistant works like an experienced crew chief. Describe the symptom the way you would to a mechanic in the paddock — what you hear, see, or feel, when it happens, and what changed recently — and it will ask the one question that actually narrows things down instead of dumping a checklist.

Every spec it quotes is fetched live from manual.rush.sr and cited, so you can verify it and it can never serve you a stale number. It checks the service bulletins before recommending parts, and it orders work cheapest-first.

Be specific about correlation. “Clunk from the rear” is a starting point; “clunk from the rear, only below 20 mph, both turn directions, doesn’t change with RPM” often gets you to the answer in one reply.

Say what changed. New parts, a recent adjustment, or the first event after storage — recency is diagnostic gold.

It’s a diagnostic aid, not a substitute for judgment. Verify any spec it quotes against the cited manual page before acting on it, and when in doubt, ask on the owners’ forum or call Rush Auto Works.
