Cherokee Fixin' - U joints

Vehicle in question is my 89 Cherokee Pioneer 4.0 5spd manual.

While greasing the front u-joint on the front driveshaft, I managed to break
the grease nipple out of the joint. It's been this way for about a month. I
want to replace the joint. I have heard that I should replace all(3?) the
joints on the front driveshaft.

I've never done u-joints before but I'd like to learn. I have a 4" vice and
air tools. What steps do I need to take to replace all three joints? (Hoping
for a detailed step by step! [Bill!]). Will I need a shop to press parts in
and out?

Can I remove the front driveshaft, drive to work w/the front driveshaft
disconnected, have the pressing done after work and then re-install? (I'm
planning to do this on Sunday, no one is open on Sunday with a press that I
know of).

Does it matter which brand of joint I buy?

Anything else I should be doing while I've got the driveshaft off?

Any other tips?


Thanks,

Carl

Hi Carl,
Take a chalk and/or center punch to mark their alignment to insure
you retain the driveshaft's balance and timing. I remove the zerk for
clearance and to allow grease to escape as I put a dab of grease in each
cup on assembly, so as not to pump air into the star:
http://www.stu-offroad.com/otherwrit...t/ujoint-1.htm Just add a
dab of grease to the constant velocity Universal Joint's centering
bearing, as it apart of the yoke and can not be disassembled:

Bill-
Thanks for the links. I'm not sure I understand what zerk to remove, and
what "cups" you mean, or the centering bearing thing. Can you be more
elaborate for a first-timer?

Thanks,

Carl

Sorry Carl, that was the best I could articulate.

Take a look at the link from Bill. The complete U-joint has an 'X' in
the center with 4 bearing assemblies on the ends. #4 shows the old 'U'
joint with the cup on (left side), #5 with it off. Complete new assembly
is on the right. The 4 bearing assemblies are usually referred to as
'Cups", the 'X' piece as the 'cross'. Picture #5 clearly shows the zerk
fitting screwed into the cross piece on both old and new.

Thanks Roy and Bill!
