If it's really the hot end - which sort of mount are you running? There are several variations.
Assuming you are using a Wade's derivative extruder (and we aren't talking about the hot end):
There are two bolts and nuts that pull the extruder down to the carriage. If the nuts have stripped out, you will either need to re-print the extruder base or shim them.
