Guys

I replaced the yoke seal on my Ford 9", I was told to torque the nut on the yoke to 35 inch pounds, did that now the ring and pinion are now not
in ajustment and are makeing noise. Will I have to remove the pig to fix the problem or Can I adjust the ring and pinion clearance through the right torque on the nut what ever that may be. I sure could use some help on what to do to fix it.

THANKS FAT40

I think you got something wrong, I think you were supposed to tighten the nut until there was 35 inch pounds of drag while trying to rotate the pinion. I could be wrong but I have done a few rear ends and dont ever remember anything in inch pounds for torque specs.

The below link has a good explanation of what you need to do. The average torque to tighten the pinion nut to is 250Ft LBS, hopefully you didnt damage anything buy having it that loose.

The way you describe is the way I did it.

fat40, you understand the inch pound preload torque is checked with the axles and carrier out, pinion gear only, after torquing to around 200 foot pounds on the pinion nut? If you used a new crush sleeve, they are extremely hard to initiate the crush! I used a solid shim pack vs. crush sleeve, found it more user friendly as I pull the differential periodically.

If you torqued the nut to 35 inch pounds it is going to destroy the rear end. A common way to check preload is to tighten teh nut to about 150 FT lbs and then check the rotational force with an inch pound torque wrench and as stated above this should be done with the axels pulled or the carrier on teh bench. You can destroy the bearings if it is too loose. If all you did was change the seal, as long as it is re-torqued properly you should not have any new noises.

Did you replace the crush collar ?

what we do in the shop is mark the yolk with a centerpunch. mark the pinion and mark the nut if your carefull you dont have to count turns but to be carefull you could.... you know your close when the nut gets tight it probably takes about 150 ft pounds to make the maks line up again

Did you use a new crush sleeve these should always be replaced as they are a one time use item.

I want to thank all that responded to the thread, I called a friend that I had

forgot about who knows about Ford 9" rear ends, he told me to torque the

yoke nut to 90 to 100 foot pounds. I did that and now the rear end is fine.

Only torqued to 100#'s? I'd check it frequently that's not enough to rely on it staying in place.
