Hi All,
I'm new here and got a bit of a problem and hopefully someone can help me!
Ok, I Have a 1991 BMW 318i Manual, Last couple of days its been making a knocking sound from the rear this happens every time I am letting my foot of the accelerator. I assumed it was either the C.V's or Diff.
So we jacked up the car a and let it run then the knocking was coming from the centre Diff so i'm going to replace the diff, but I don't know what the diff ratio is for my car and does it makes a difference on what the diff ratio is, like if I use a diff out of the same model but auto.
Any help would be appreciated!
Thanks
