  We report multifrequency observations of the $\gamma$-ray blazar 0528+134
with the Effelsberg 100-m telescope, the IRAM 30-m telescope, and the NRL Green
Bank Interferometer. 0528+134 underwent a major radio and mm outburst in 1993 a
few month after a very strong outburst in high energy $\gamma$-rays. A similar
behaviour is indicated for the weaker $\gamma$-ray outburst in May 1991 and the
mm activity in the beginning of 1992. This result fits nicely to the general
finding that blazars are bright in $\gamma$-rays preferrentially at the
beginning of a radio outburst. 0528+134 was observed with a global VLBI array
at 22$\,$GHz in November 1992. Within the IRIS-S and EUROPE geodetic VLBI
observing campaigns the source was also observed regularly at 8.4$\,$GHz. A new
VLBI component which is not present in data at 22 $\,$GHz from 1991 also
exhibits superluminal motion. Backextra\-polating in time we find that the new
component was expelled from the core in the first half of 1991, near the first
$\gamma$-ray outburst in Mai 1991. Newest VLBI data indicate the appearance of
another new component in 1994. Although this new component has yet been found
only at two epochs, it appears to move superluminally and may have been
expelled from the core between fall 1992 and summer 1993, i.e. near the time of
the second gamma ray outburst and at the beginning of a strong radio outburst.
