How hard is it to remove or replace the gears and rear-end bearings on a '94 Aerostar?
It is hard if u don't know how or where to start,u will need the
rite tools for the job.The rite tools make it real easy!!! The
bearings r pressed on,u will need a 10 ton press,...gears , well
they have to be set up so they won't howl or grind while,the rite
shims need to be used.If ur good at turning wrenches it will take
about 4 hrs,butif u have no clue what u r doing ,well good luck.U
might try to find a ASE cert. tech.to service ur rearend.
