Can anyone tell me how or is it not adjustable? Mine vibrates too much so I need to tighten it down a bit. Not sure why it's vibrating ALOT hehehe lol -K
To Adjust it left/right or front/back, loosen the bolts and move it around. To adjust up/down use shims. Your locking mechanism may need to be adjusted also after this. Same thing, loosen bolts and move it around and add shims if you need to. Since it vibrates, you may want to look for bad hinges first. Maybe worn rubber stops or loose trim are what are causing it also.
I think the stoppers are worn. Doesn't seem to be any adjustment screw with them, just need new ones or slightly bigger ones. -K
