Well update on this.
I went this morning and got under the car and to my surprise 1 of the bolts were completely sheared/snapped in half other one was missing a lock nut.
Then i decided to remove all of the bolts and nuts.
Inspected the Guibo and it still looks in good condition.
Went to Bolt It with a sample and after a discussion i decided to replace the old bolts and nuts with Allan cap bolts of same length but stronger grade 12.9 M10 x 1.5 and new lock nuts. See attached pic.
The old ones were grade 10.9 M10 x1.5.
Tightened everything back up and torqued it down.
Took the car for a test up to 120km/h and all was well, previously since i bought the car it had a vibration so i thought it was the propshaft but didnt have funds to buy a new one but now it seems to be remedied.
So when i finally got my @$$ in gear and tackled this issue.
I was very lucky just the thought of having to break down on a long journey would have been a pain in the but.
Now the durability test of this repair and will update.:fencelook:
Costed me R60 and some of my time.
Thanks all for all the input.:thumbs:
