Rear trailing arm bolts.

The ones Thad has been supplied to me are of the 8.8 grade ...  Shouldn't they be 10.9  when we are talking suspension bolts ?

I would not rely on 8.8 strength bolts. From what I can find you should use 10.9 in suspension applications.

Guess who sold me the 8.8 bolts Jon ?

[Oetker]

Just had a look in the shed.
I have several trailing-arms with bolts.
They are all 8.8 .

[krede]

We'll... That solves the issue

Came to think about it..... guess they had to make them 8.8 quality in order to allow people to better cut them when they seize
