Another pair of handy hints:
*If* you break a leaf (for whatever reason) - at minimum replace *both* springs on that side.
If you're doing the work, be sure to check the location of the centering pin on a new spring pack you may have purchased from a "generic" supplier (or before you have a new set made up).
Some OEM spring packs have the pin "off center" of the spring length.
Ex: a 30" long pack with the pin at 16" rather than 15"..
Learned that one the hard way on a TT many years ago.
The (incorrect) replacement "pin on center" spring -from a trailer supply- went about 5K miles before it also broke.....and I did a lot of head scratching until the light went on..:h
