What is the torque specs for differential cover?
Torque specifications vary depending on the material and grade of fastener, and the material of the diff cover itself. Follow the instructions that came with your cover, they will usually fall between 20-30 ft/lbs. ARB for example, recommends right around 25 ft/lbs for most applications.
What is the torque for rear axle U bolts?

How much backlash should a differential have?
Keep the backlash variation under 0.005″ if possible. In a perfect world no variation would be the goal. However, even with a straight case the backlash can vary 0.005″ without any negative consequences, so this is an area where each assembler will have to decide how much they are willing to allow.
How do you tighten a differential cover?
Use medium strength thread locker (such as Loctite 242) on the bolts to prevent them from loosening. 6. Carefully place your new cover with gasket on the differential housing and install the cover bolts. Tighten bolts in a criss cross pattern, a little at a time.

Is it OK to reuse leaf spring u-bolts?
This is one of the single most commonly asked questions out there when discussing leaf springs and related components. We get a variety of reactions when we advise our customers that reusing U-bolts is never a good idea.
Do axle u-bolts stretch?
Reason 1: U-bolts are often a torque to yield bolt. This means when you tighten a U-bolt to its correct torque spec, the bolt stretches to achieve that level of tightness. However, the U-bolt can only stretch so far, each time the U-bolt is tightened, it is closer to failure. To us, it’s not worth the risk.
