What exactly is pinion preload?

Nov 02, 2003 3 Replies

So I'm thinking of installing different gears. I'm doing some research as to what is involved in setting up the gears and I've come along "preload". As far as I understand it's the torque required to turn the pinion but the whole thing is still unclear. Can anyone explain? I understand that it's measured in units on the order of in/lbs. For a f-body 7.625" 10 bolt the spec is 25in/lbs which doesn't seem like much at all..

You really should try Google first next time. These two came up on the first page when " pinion preload" was entered.

Damn, that's a nice site. It is so book marked and e-mailed to myself just in case. And a very clear explaination of all the set up involved. I was kind of foggy on that all myself, but not any more. Guess I can do my own, after all.

didn't even bother to go to this one...

Ok. Second one *was* very useful for detail of the procedure involved... Very good ideas I hadn't thought of from reading the first one.

Thanks muchly for that post.
