whats the preload supposed to be? and is the preload directly effected by how tight the carrier is in?

i know i had to about kill the old carrier to get it out, it was in so tight......CAN it be in too tight? i know it can be in too loose.

 

I'm fuzzy on this; haven't set one up in a while, but I think pinion preload is to measure the bearing preload, i.e. no carrier / ring installed.

tightness on the carrier is fairly normal; can't have any slack there, if you drove on it that way a long time, it was probably right when tight.

 

i assume you are talking about the preload on the crush sleve? if so it is very small, i don't remeber off the top of my head, but it is in the In./Lbs. range not much at all. it is just a way to make sure the crush sleve is, well, crushed properly. you CAN overtighten, and if you do you crush the sleve to much, and have to get another crush sleve, and try again.

 

No carrier installed, jut the pinion assembly.

6-7 pounds/inch for used bearings

12-15 pounds/inch for new ones.

If you overcrush the sleeve you have to start over, or use a shim under the sleeve, but I'm still not sure where to get these.

 

i'd have to look but i was thinking more like 15 in/lbs used and 25 in/lbs new

 

Specs came from my Randy's Ring & Pinion setup book, FYI. I've done several rears for avarious makes and models using this book and so far zero problems.

 

i read 20 to 25 somewhere as well, however i dont know where....ill look around...lets decide on one or the other though

yeah i saw that, that makes me happy....i CANT find a torque wrench that reads 15 in lbs....but i CAN find one that reads 20....BOOYAH --he exclaimed with great relish--
