FWIW,
You will probably have to go to a specialty fastener store to get the grade-8 stud.
Don't be tempted to use a piece of all thread, it may strech or snap off inside the gear and cause more problems.
Lube the stud where the nut contacts the washer.

I found a pretty informative vid on you tube detailing testing your vac system and brake booster

I still have cruise so it might be my booster.
Thanks for the video Nonrev, I'll have to dig out my vacuum gauge and check my booster now. Pretty cool to find a video specifically for our trucks. I also noticed he has one on the rotors & king pins which I'll watch. I did the passenger side king pin already (about a year ago) and need to do the drivers side plus rotors now.

89-91 Dodge Diesel vacume pump
Do you have the 2 diaphragm type vacuum pumps or the vein type vacuum pump? Being that your sig only shows '92 model trucks/vehicles, you should have the vein type pump. However, you mention a diaphragm is why I'm asking.
The diaphragm vacuum pumps can't be resealed, only replaced at the cost of about $160 each. The vein type pumps can be resealed. The reseal kit for the vein type pumps is Cummins P/N 4089742.
