Karen, I will change what I tell people with regards to torque values on
the bolts on the cv flanges. GO with Karen's Recommendations.

A little history on why I changed the one ton instruction torque for the
inner cv bolts.

Yes, the manual says 75 ft-lbs, which is a lot. It also says you can't
re-use the bolts, which makes sense
given this very high torque. I installed ours to 75 ft-lbs originally, and
had that torque in the instructions.
Then, when we had to replace the engine at Manny's house, he complained
they were torqued too tight (we had to
undo the axle to clear the oil pan to get the engine out...) So, I started
double-checking,
talked to KenH, did a little research. Both Manny and Ken said 75 ft-lbs
is too high and they never do them that tight.
The various technical docs I found backed them up.

As a result, the one-ton kit instruction now says the following:
"Apply loctite to the inner CV joint bolts and torque them to 55-58 ft lbs.
(The manual states these should be torqued to 75 ft-lbs and replaced with
new ones
if they are removed. However, that exceeds the recommended torque for ASTM
Grade A574 bolts,
which are stronger than Grade 8.)"
