Five-dimensional domain walls in gauged $SU(5)$ generate a position-dependentsymmetry breaking pattern along the additional dimension. We analize theperturbative stability and the 4D spectrum of these walls in theself-gravitating case, in terms of diffeomorphism- and Lie algebragauge-invariant field fluctuations. We show that tachyonic modes are absent,ensuring perturbative stability. As expected, gravitational tensor and vectorfluctuations behave like its counterparts in the standard $Z_2$ domain walls.All the Lie algebra valued fluctuations exhibit towers of 4D massive modeswhich propagate in the bulk, with a continuous spectrum starting from zero. Allthe would-be 4D Nambu-Goldstone fields, which are gravitationally trapped inthe case of a global symmetry, are non-trivially absent. However we find nolocalizable 4D gauge bosons, either massless or massive. Instead,quasi-localizable discrete 4D massive modes for the gauge field fluctuationsare found, along the spontaneously broken directions.
