Diagnose before you fix

Push the carriage slowly through its full travel with no springs attached and listen. A rhythmic tick that repeats at the same point is a wheel; a gritty sound throughout is debris on the rail; a rattle only under load is loose hardware; a twang on release is a spring touching the frame.

Doing this with the springs off is important — spring noise masks everything else.

The fixes, in order of likelihood

Clean the rails with a dry cloth first, then a barely damp one. Grit is by far the most common cause and it also does the most damage, scoring the rail permanently if left.

Then check every frame bolt. Reformers loosen slightly over the first few months as the frame settles, and a quarter turn on four bolts fixes a surprising amount of rattle.

  • Wipe rails clean — grit is the most common cause
  • Spin each wheel by hand; a rough or noisy wheel needs replacing
  • Check and snug every frame bolt
  • Confirm springs are not contacting the frame at rest
  • Check levelling feet — a rocking frame amplifies everything

Noise you cannot fix

A scored rail will keep making noise no matter how clean it is, because the wheel is riding over damage. Rails can sometimes be replaced; on cheaper machines they cannot.

Unsealed bushings also get progressively louder as they wear, and there is no maintenance that reverses it. If a machine got noisy within its first year and cleaning does not help, the bearing type is the answer.
