I read on one of these newsgroups about someone who had a minor problem with
feeling a "bump" either on coming to a complete stop or just taking off from
a stop. They claimed the problem was in the driveline and not the brakes,

would like to know if anyone can tell me what to check or how to grease this
yoke (and which one it is) so I can do it myself. I don't always have the
ability to send my truck to the dealer because I'm currently working 8-5 and
can't be without it.

and get all the 4x4 items 'spruced up'.
