Looks like a good oil leak from my left output shaft, right at the union
with the case, although I must clean it up a little better and get a really
good look as it is throwing oil everywhere. I am 90% sure this is where the
leak is as I had to put 1 qt fluid in the front case. Can anyone tell my how
tough a job this is? Will I have to pull the front case to replace this seal
or can the output shaft be removed by disconnecting the outer shaft?
Clearance? Tools? I do not own a compressor unfortunately.
Or should I just let it leak and refill in the winter??
If you're talking about the front axle leaking, this is what I'e
they all do it...
it's not worth fixing..
just keep topping it off.
if you're dead set on fixing it... getting the axle out of the truck
isn't that bad ( or it wasn't that bad when I did it a couple of weeks
ago, but I had a lift and air tools)... I'd not attempt it lying on
my back in the driveway. my seals weep a little on my '88 K2500 and I
just pull the fill plug at every oil change.
If you want to do the job, it's not that difficult. You can
do the left side without removing the entire axle. The
trick is to move the wheels all the way to the left
position, remove the four bolts that hold the sway bar
to the frame (not the link that holds it to the lower
control arm), remove your 6 bolts that hold the outer
axle shaft to the inner axle shaft....then, you can
pry the sway bar forward just enough to get the
outer axle shaft around the inner axle shaft. At this
point, you can just smack the inner shaft and it will
pop out (maybe, I'll discuss that in a bit). Sometimes,
it will interfere on the frame, you then remove the
top bolt that holds the front diff up in the frame,
and loosen the bottom left side bolt. This allows
the front diff to drop just enough to get the shaft
On an older vehicle like yours...often, the retaining
clip on the left side shaft gets all buggered up inside,
and you can bang away on that shaft all day long
and it won't come out. If you cannot get the
shaft out with a few good smacks with a good
size hammer, forget about fixing the leak that
day. The only way to get the shaft out at this
point is to cut the flange off so that you can
separate the case halves and pull the stub
out. Pretty nasty job. And it will cost you
a few dollars.
Sounds good until you get to the last little "buggered" up part, hehe.
I just might attempt it as you say when I get a chance. I Topped it off
about a month ago it was down over a quart, and seem to be leaking at a good
rate by the mess it makes in my driveway.
Should I worry about the case running dry during the summer months when I am
not using the 4 Wheel drive?
Thanks I will post back the results when I attempt it.
