The bolts are TTY(Torque to Yield). If you over torque them, new ones are needed.

 

Torque All 11mm bolts torque to 22ft/lbs

All 11mm bolts turn and additional 90 degrees

 

Depending on year and bolt, measure the old bolts to see what size you need.

If you have 2 different length 11mm bolts 3.94" and 6.1"

Tighten 1-8 in sequence an additional 90 degrees

Tighten 9 and 10 an additional 50 degrees.

 

If you have all same length 11mm bolts 3.94"

Tighten 1-10 in sequence an additional 70 degrees.

 

 

Tighten all 8mm bolts #11-15 to 22ft/lbs.
