Re-gearing my 92 f150 sas to 4.56, these are the final patterns.
Ill have to find my spec sheet but im .002 off on pinion depth and back lash is .006 and my pinion nut torque to around 200 ft lbs with 20 in lbs of preload.
How did I do?

 

I'd run the pattern,but would open the BL. Spec is .008 - .015

 

Where did you get those specs?
Everything I read either said .006 to .010 bl and one said .007 to .009 bl.
Axle is out of a 79 f150 dana 44.

 

I assumed an 8.8.
