351m water pump
With today's crappy parts from mcparts stores, am I crazy to think about rebuilding my water pump? What goes bad on the water pump to make it sloooowly weep out the weep hole? Has anyone on here ever rebuilt their pump? Where would I find these parts? What are the parts called?
Thanks for any help. Chris

I always just went to the parts store and bought one. I expect it takes a press at least to reassemble after you find a way to pull it apart to put in seals ... that I've never known to be readily available to a DIYer.

I believe internal seals go bad and then the sadness starts with the weep hole drip. X2 not sure it you can even get the stand alone parts to rebuild it. Good luck.

As others have stated the seal usually starts to leak sometimes followed or caused by worn bearings.
Rebuild kits are available for some agriculture applications and I also believe the heavy truck industry. I did get a small farm tractor pump kit for a farm tractor years ago when a new pump itself was not available.
I quick google brought me to this site Dead Nuts On, unfortunately I didn't see anything for 351M/400 applications. The other Ford applications shown may use the same parts.
The world seems to have accepted that water pumps are a replacement item and are not rebuildable. I have started keeping the original Ford water pumps, alternators, & starters a few years ago instead of returning them as cores. I much prefer the quality of the Ford parts. I haven't had to rebuild a water pump yet, so I will be watching this thread to see what the responses are.

There are people that will restore the pumps, check ads in Hemmings. Those guys restoring Mustangs don't give up on date coded parts. Only downside is sending in yours. Get a crap replacement and send your old one to a rebuilder while you wait for crap one to let go.

I've found water pumps to be one of the better aftermarket parts as long as you pay up a little buy a higher quality unit. I'd just buy one and move on.
Master cylinders, starters, alternators are a different story.
