How To Fix Volvo Trunk latch
Primary problem with this trunk latch mechanism is cheapness. Secondary problem is a broken axle which operates latch release lever.
It should have never happened if axle was built of solid plastic instead of hollow.
You can try to glue it, using J-B plastic Weld and superglue. You can buy J-P weld from Home Depot for about $10.
Axle is hollow on inside. Something will be needed inside the axle to help bond it, otherwise will break again. Find a nail of same length and as close to diameter of axle hole as possible. Insert nail inside the axle and cut it to size if long.
Fill up axle hole with J-B Weld Plastic putty glue, you won’t be able to get much in there but try your best. Insert nail inside the axle after filling it up with putty glue.
Use superglue to instantly bond the axle making sure it lines up properly. Leave it dry for few hours and will create a strong bond. Do not leave any glue residue on outer part.
Installation reversal of removal.
