I took my Astra to the garage today for the LSD and the Paddle clutch fitting, I had big problems with both,
The problem with the LSD lies with the speedo drive that covers the differential, it's like a worm gear
It is made of plastic and slots snuggly into a recess on the diff, easy to get on but the guy is having trouble getting it back off to put onto the LSD.
Is their a way of doing it without breaking it, I tried to buy a new one from Vauxhall and they told me its not a part they sell.
If i leave it off i'll never know how fast ( or slow ) i'm going.
If it breaks am I up **** creak?. If their's no alternative I suggested grinding the lip of my old diff down until the plastic worm gear just slides off, but that will leave me with a knackered diff in case I need to put it back on.
