Well, after 221,000 the rear pinion seal is beginning to fail. I have a seal and need to know the rear pinion nut torque spec for the flange.

 

help

 

thanks,

Danny.

I don't have my manual at work to look it up. However I've done several of these types of seals on other vehicles like my Suburban, and FJ40 Toyota Landcruiser. Basically, you mark where the nut is now, count the number of exposed threads on the pinion before you remove the nut. Remove nut, replace seal and put it back on to the same place where you put your mark with the same number of exposed threads then it shouldn't be a problem.

The 87 EA82 shop manual says 123-145 ft-lb and to stake the nut after tightening.

for seal replacement this is the proper method.

 

if you actually retorque it you may overtighten the crush sleve and cause bearing failure.

 

I would recomend using loctite on the nut and lube the seal really good.
