Is there a 'degree' mark after the 90s?

It is not a misprint....it means you have to torque all the bolts to proper torque specifications, then an additional ninety degrees on each of all the bolts then an additional ninety degrees again on each of all the bolts.

Yes, I understand that. I just don't understand starting at 108 ftlbs ,then turn 90 then turn 90. The 108 has to be a misprint...

3 steps. 26 ft. lbs. Then-90° + 90° In proper sequence, that is what i got!

With a new bolt kit! These bolts stretch to yield the final torque. That is first step 26 ft. lbs. all bolts, then + 1/4 turn all bolts, final step + 1/4
turn all bolts in prprer order.
