Hello –
Recently I changed the oil, and lubed the chassis of my ’89 (4wd, Xtra
Cab).. I greased all the points per the manual. Ever since then, I
can hear a faint ‘whining’ sound coming from [I believe] the transfer
case. It’s consistant with the motion of the truck. (Doesn’t matter
what gear it’s in, or what 4wd mode is selected)
The only thing I can think of is that I overfilled the slide yoke for
the front diff / transfer case. (I could see the shaft extend as I
filled it) Maybe it’s putting forward pressure on a bearing, and
that’s making the noise?
If this is the case, what can I do to ‘deflate’ the yoke so I can make
the noise go away?
Otherwise, any other ideas?
TIA –

There is usually a hole in the end of the shaft, that lets excess grease
out. You might pull the shaft off (a pair of 14mm long handled
wrenches) and try compressing it by hand. If it won’t compress that
way, see if there is a hole that is plugged, if not, pull the grease
fitting and see if you can get the excess grease out that way. Only
takes a pump or two of grease on the slip yokes, or what I sometimes do
is pull the shaft and just paint some grease on the splines and put it
back together.

Yeah, I was looking for the exit hole too… Thanks for the suggestion,
I’ll drop it out of there and see what I find.

Remove the zerk and drive it for a while.
