What's so different between the two that warrants that increase per unit?
What torque setting should they be fastened to?
Talking of torque. When refitting the diff housing, what torque should the 11 and 16mm bolts be done to, and the 3 speedo drive housing ones? Haynes lists various torques but none of those. When it comes to sealing, I didn't notice any sealent upon removal. Is that correct? If not, what should be used?
