Update on proceedings.
You can all now sleep well at night (I think).
Stainless replaced one at a time with HT.
I got some new HT bolts rated R and have tightened them to 18ftlb. (still can't find a table showing yield and proof loads for R.) Bolts are new not plated and I coated with copper slip. I will be checking for tightness once car in use.
using % accuracy for a given method of tightening a bolt (found in a table by one manufacturer)
Feel or operator judgement +/- 35% = 11.7 to 24.3 ftlb
Torque wrench +/- 25% = 13.5 to 22.5 ftlb (LASER tools 5 - 25Nm torque wrench)
Can anyone with an original untouched axle look and see/confirm R grade HT bolts were originally used.....there is an R on the head.
