There are 10 bolts holding the ring gear on. At least, they should all be
retorqued using a crowfoot adapter, then chain-wired. But replacing them and
torquing & wiring new bolts is best. Stock bolts are over-hardened and
sometimes break in use, plus under each bolthead is a serration designed to dig
in and help lock the bolt. But the carrier surface the boltheads contact is
too hard to allow 'digging in' so the effect is lost. Also, the hardened
stock heads are not drilled while U.S-made replacements from the vendors are
pre-drilled. Altogether, not an easy task if you include R & R-ing the ZF to
access the bolts. Even inspecting for the possible presence of safety wire
already there is complex; they are not visible from the drain plug area except
with a flexible fiber-optic tool.
For extreme competition, the ZF drain AND fill plugs should also be safety
wired; some race orgs require this. FWIW- J Deryke
