2023 GMC Sierra 1500 — car pulls right even though alignment is green

ShiftDIYerCommunity StarterMay 14, 20262023 GMC Sierra 1500 AT4Nationwide

2023 GMC Sierra 1500 AT4, about 53,500 miles. Alignment printout is within spec, but the car still wants to drift right on a flat road. Tire pressures match. Would you cross-rotate tires to check radial pull, or look harder at caster/camber side-to-side?

Ask what changed right before it started. A pressure test beats staring at a dry driveway if the 2023 GMC Sierra 1500 is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. If you share a photo of the worksheet, easier to sanity-check. Wrote this up on my lunch break.

Intermittent stuff lies if you only catch it once. Write temp, speed, and in-gear vs coast when the 2023 GMC Sierra 1500 does it — then decide on parts. If the cheap test changes it, stop and reassess. On “car pulls right even though alignment is,” that was the fork that mattered for me. If you share a photo of the worksheet, easier to sanity-check. Happens in gear, not in park, for what that's worth.

I hear you, though I'd still want a second check. Two 2023 GMC Sierra 1500s can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. Do that first. I'd rather be boring and correct. I'm keeping receipts and dates in one folder.
