Re: gear lube
I think Royal Purple has the hypoid lube in it, read the side of the bottle. Remember it is something you can have too much of.Central TEXAS Sleeper

Re: gear lube
you can have too much? should i use the purple or regular fluid and just add the additive?Comment

Re: gear lube
Too much posi lube will cause the clutchs to do something bad. Look at the bottle, it should say. Regular and the additive is a garentee but I'd check.Central TEXAS Sleeper

Re: gear lube
thanks. i guess that trac-lock and limited-slip are the same?Comment

Re: gear lube
Is it clutched or gear drive? If its a clutch or cone style, you need the lube. Gear drives.... don't know.Central TEXAS Sleeper

Re: gear lube
A Trac Lock is a clutch-style limited-slip and does need friction modifier (I don't think "hypoid" is the answer here...that's for the r&p...all automotive gear lube is hypoid gear lube...correct me if I'm wrong).
A Detroit Truetrac is a gear style and should not require friction modifier.
Detroit is not the manufacturer of the Trac Lock...so which do you really have?Comment

Re: gear lube
I just recall that line from my '64 service manual, not sure if hypoid is right either. However yeah, you need the modifier for clutch or cone limited slips.Central TEXAS Sleeper
