Grease Fittings- 1977 620KC

[Randalla]

In the process of rebuilding my steering and front suspension.  Curious to know what the thread pitch is on the grease fittings, and how many there are. I quickly counted 7, but wondering if I may have missed a few.

Each knuckle has an upper and lower grease nipple. (4) The lower link fulcrum pin has plugs on each end that are removed and a grease fitting is installed for greasing, then the plug is put back on.(4) There are 6 steering ball joints that may have grease fittings. The good ones do. (6) So... 14 at least

Guess I better keep looking😁. My 7 were the tie rod ends (4), Center link (2), idler arm (1).

Forgot the top of the idler arm.

I run into this question a lot. Thread pitch? I have no freakin idea, but I do remove old zerk fittings from parts I replaced before I throw those old parts away, so I have a good stash.

 

Any auto parts store will have bubble wrap packages of zerks, and they're only a couple bucks, so buy a couple packs and get what you need. Put the rest in a bin for when you need them ten years from now.
