With weak verbs, consonant sounds shift, often in the form of suffixes (endings) added onto the stem.
In the case of strong verbs, the vowel sound shifts, often within the stem.

I see that this is from a German course. The statement that "In the case of strong verbs, the vowel sound shifts, often within the stem" is fairly straightforward. It says that in verbs like "ich fahre - ich fuhr" the vowel in the stem changes ("shifts"), in this case from /a/ to /u/. I do not, however, see why it claims that this "shift" is "OFTEN within the stem". Where else is it supposed to shift?
The statement that "With weak verbs, consonant sounds shift, often in the form of suffixes (endings) added onto the stem" does not make any sense. In words like "ich suche - ich suchte" nothing is "shifting"; the past tense is made simply by adding -t to the stem. I suggest that the author of this course does not know what (s)he is talking about.
