I know this isn't engine related but i always get the best help from this group. On my 99 f-150 the seal for the back window fell in. It isn't leaking water yet but i would like to put in a new seal. I have the manual sliding center window that has 3 sections. What all has to be done to install a new seal?

Also when driving down the road the drivers mirror shakes so you dont get a clear picture of what is behind you. It is just the glass that shakes in their. Is their something inside there that can be replaced becuase the passengers mirror doesnt shake at all? If there is something that can be replaced how do you dissassemble the mirror?

And finally the rubber boot around the shifter has torn. What parts of the dash and steering column need to be dissassembled to replace this boot?

Thanks in advance to anyone that can help me with these questions.
