Does anyone know how hard it is to repair the ignition linkage in the steering collum of a 1990 F-150? How about the rear end seal? Thanks.

 

Which seal on the rear end? I can think of at least three unique ones.

 

Honestly, its a royal pain in the *** because you have to tear the column all apart to do it but it can be done.

 

So it's an eight-hour job? Other than a wheel puller are there any special tools required?

 

Where the drive shaft enters the diff.

 

depends on what is broken in the ignition switch components.
if it is just the key cylinder, that is about a 2 minute job. if it is the ignition actuator that is broke, that is roughly a 1.5 to 2 hour job. if it is a bad ignition switch, that is about 1/2 hour to swap.

a pinion seal replacement is not that bad. remove drive shaft, remove pinion yoke, remove seal, and drive new seal in. anywhere from 1/2 hour to 3 hours, depending on whether it wants to fight you or not.
