A DFW homeowner called us back about their NordicTrack X32i treadmill with a familiar complaint: the machine had been serviced the year before for a belt replacement, but it never felt completely right. Now the walking belt was visibly rubbing against the side of the deck, creating friction, noise, and uneven wear. This is the kind of issue that does not fix itself and gets worse the longer the machine runs.
The Problem
The homeowner reported that the treadmill had felt slightly off since the previous repair but was still usable. Recently, the walking belt started drifting to one side and rubbing against the belt guard during use. They were concerned about damaging the new belt and wanted the machine running the way it should have been from the start. On a high-incline trainer like the X32i, a misaligned belt puts extra stress on the deck edges and the rear roller bearings every single session.
What We Found
When the tech arrived and ran the machine through a full inspection, the walking belt was tracking noticeably to the left. The rear roller tension bolts were uneven, with one side carrying significantly more tension than the other. This indicated the belt had never been properly centered and tensioned after the previous installation. Additionally, the walking belt itself showed early edge wear consistent with weeks of side contact, and the deck surface had light scoring along the left rail where the belt had been rubbing.
How We Fixed It
The tech methodically re-centered the walking belt using controlled adjustments to both rear roller tension bolts, running the machine at low speed between each adjustment to confirm tracking. Once the belt was centered and moving straight, both sides were brought to proper and equal tension. The tech then tested the machine across multiple speed settings and at full incline to confirm the belt held its line under real operating conditions before closing out the call.
The Outcome
The X32i ran clean and quiet with the belt tracking straight through the full speed and incline range. The homeowner said it felt better than it had since they bought it, which is exactly where it should have been after the first repair.
Key Takeaway for Equipment Owners
A belt replacement on a treadmill is only half the job. Proper belt centering and tension calibration after installation is what determines whether the repair actually holds. If your treadmill felt slightly off after a service visit, or if you notice the belt drifting toward one side during use, do not wait until you see visible rubbing or edge wear. Catching a tracking issue early saves the belt and protects the deck from scoring that cannot be undone.
