Hi I have a Lincoln Navigator 1999 and I was
wondering can I reuse the main bearing
bolts/studs?

Thanks a lot, I was also wondering do I need to use some specific torque lube to get the right torque? ;)

Actually lube will cause the bolt to be over torqued which can lead to bolt failure.

So if I am reusing old bolts I should not use lube but if I am changing them like the head bolts I should use torque lube?

One should refer to a shop manual to see if a bolt should be lubed or not. On some headbolts they should be oiled and others not. I will see if I have access to the Lincoln Navigator shop manual here at home. I'll let you know in a few minutes.

According to Ford you need to use new bolts. My detailed post is held up by security here.

According to the Ford shop manual it doesn't specify whether the crank shaft main bearing and side bolts need to be replaced, but in the Ford parts catalogue, the main bearing bolts and the side cap bolts must be replaced after being removed. Also the workshop manual said to lightly oil the head bolts with a rag using plain motor oil. In addition it said to install head gaskets dry and do NOT use any copper seal or other products. Also I work at a local Ford dealership in the parts department and have access to this information.
