Can anyone help me? I have got a replacement, diff for the 2ltr Omega. It didn't come with the front bracket. So I was going to use the bracket off the old diff I am taking off. I have read that the 3 bolts have to be replaced? I have looked everywhere for new ones, but can only find, ones removed from diffs in Russia. Can these bolts be reused, as from what I have read they are torqued and angle tightened? Or could a normal High tensile bolt, be used instead with some blue thread loc?
I have attached a picture to show the bolts I mean. Number 8 arrowed.

Thanks in advance for any help.

Clean and reuse the old ones.

Thanks biggriffin, for the quick reply. Will some blue thread loc, be needed or just fit dry?
I thought I would ask as the Haynes manual, says renew bolts because of the angle settings.
Stage 1 90Nm
Stage 2 Tighten 45 degrees
Stage 3 Tighten 15 degrees

If you follow all of that, I suspect you'll be the first person ever to do it 8)
If I was paranoid about them, I'd use a torque wrench for the 90Nm before adding a bit more :y

Thanks both. Knew I would get a decent answer from this forum. :y

Yup, just did mine FT.

Personally I'd just put them back in and do them up tight.

Hi
Hope everyone had a good Christmas.
Hoping to get the diff replaced on the 2ltr, in the next week. But have another question, before starting it. Can the retaining clips, on the diff side of the drive shafts be reused aswell? I have the proper tool, to remove the drive shaft, from the old diff so I can fit them in the replacement diff.
Thanks again for any help.
All the best for Next year.

They pop out and back in without a second thought ;)

Thanks DG for the quick reply. Hopefully this will be the last big job before it goes for MOT.
Thought it might of been rear wheel bearings, but the noise is a high pitch wine, from the back that gets unbearable. It doesn't change pitch on a straight or turning in any direction. So going to change the diff and hopefully the noise will go. :)
Fitted new exhaust manifold without the EGR and SAI. New downpipe off a 2.2 and O2 sensor fitted. All welding been done. New brake calipers, discs and pads done front and back, including the handbrake system. All front suspension done. New back springs and shocks. So should be ok with all that. So hopefully will pass.
Only problem then is will have my 2.6 saloon, which has had loads of work done to it. The wifes 2 ltr estate and a Astra G, with the 1.6 8v engine in, that she got to use while the estate has been worked on. But she likes the Astra so much, that I have been told the saloon has to go.
All the best to you for next year.
