power steering swappable from 87 to 91?

[Micha]

hi guys,

my power steering (91 xj) has some hard spots - it is harder to turn the wheel when i come back from a left turn slightly before it centers...
no binding though, the jeep is not modified in any way.

will the 87 xj components fit? can have those parts for free...
