P30 Disc brake vs drum brake ball joints
https://ibb.co/hmHLG0S Ive had issues with the ball joints on my p30 since ive owned it. Ive had shops replace them twice in my ownership, and the rest of the time they told me the ball joint...

It seems that theres often 4 options for lower ball joints when you look for them;
Motorhome/stripped chassis with rear disc (part number 6511) *this is the correct one*
P30 standard van with rear disc (part number 6175)
P30 with rear drum (part number 6129)
F44 heavy duty chassis (part number 6117) *im not sure what truck these are for*
OK what would be the difference between the stripped chassis and the P-30 with rear disc?
Im not sure, its different part numbers so id have to assume chevy did something to change the front end for each application.
I assume the p30 with rear disc means a regular bread truck, and the stripped chassis got some minor change when they built them for rv manufacturers.
To be clear i only did this research as it applies to my 1993 model year, however it seems to be the same confusion for most of the 90’s
