was wanting to know if it is bad to spray the u-joints on the drive
shaft with wd-40 or with other lube sprays?

i have a 99 S-10 ext cab with 32,000 miles and i spray things down to
keep things from rusting and i even sprayed the parts outside the
transmision including the u-joints.

is this not a good thing to do?
my truck looks like it did when i bought it new and it's only seen snow
the first year and a half since i've had it...............i have a work
car for the winter times now.

thanks alot.

WD-40 is NOT a lubricant.  The WD means "Water Displacement."  It is plain
bad for anything that needs lubrication or long-term protection.  If your
goal is to remove rust or grime without water then it's fine.

Not sure with regard to the main intent of your question though.

PLus it may was the grease out of the joints.  If you want the truck to stay
un-rusty then spray it with rust-o-leum, its about the same price too.

If you are just applying a light coat to the outside I don't see a problem.
If you spray enough to wash out any of the grease from the bearings, that
would be bad. Regreasing the joints, if they aren't sealed, would be a good
idea.

I had a motorcycle sprayed all over with WD-40 (including brake disks)
standing outside for >2 years.
2 Months ago I started to clean it, put the new engine in and went riding.
No rust, brakes doing fine after 500meters (no, no play bike, this one has
260km/h topspeed and I've no suicidal tendencies).

Good protection, this is.

That is good. I would have thought it would need reapplied. Always liked it
myself. We call it "Debbie D" here, after my now grown nephew who pronounced
it Debbie D when he was a tot. ;-)

It wasn't WD-40.  The WD-40 either dried up to gummy little balls within
weeks or washed off.  There's a recurring discussion of WD-40 in rec.guns
(where rust is a real concern for safety).  Some manufacturers explicitly
warn against it (e.g. Ruger).

It's a fine non-water wash and a decent solvent.  Nothing more.

WD-40 was was designed to protect metal from condensation and the
resulting oxidation, it works great for that.  Obviously it won't work
if exposed to weather.

Well, he doesn't state where he lives. Obviously the Pacific Northwest of
the US would wash it off much faster than the arid Southwest.

There are so many new products that are much better and last much
longer, why use one of the oldest  ones thats not very good at
anything and dosen?t last. ...My 2 cents...

WD40 is a pretty good cleaner.  It will melt away grease so if there is
even the slightest crack at the grease seal for the u-joint caps, it
will get in and eventually dry out the u-joint.  This is not a good
thing.  Now if you can pump in new grease after cleaning it so you force
out any WD40, then go for it.
