Looking at swapping all the badges on my GTC to Opel badges (cleaner look imo) Im guessing the 2 badges on the bodywork are gonna be a pretty straight forward swap, havn't had a proper look yet, but for the steering wheel am I going to need a new wheel or airbag? 

Looking at the way the badge is set in wheel i'm assuming this is the only way round it, any of you guys swapped the badges over and have any info for me? Cheers

Going To attempt this on the weekend, I've neglected my rear brakes to the point I have no material left (approx 2-3mm I think) and my brakes are making one hell of a noise when braking hard.
I'll follow the how to that's on here (great guide, I did the front ones following it) do I need a winding tool? As I've not got one ☹️

Has anybody with a 14 plate J ever changed the daytime running lights to a better LED before?

But i want to do a few upgrades on it if i can, and this forum seems to have the best people who change things about and generally make things work where others say it can't be done.

I'd really like to upgrade the CD400 radio unit i have to one of the sat nav units with bluetooth etc, the ones with the colour screen in the top of

Hi is it possible to put half leather Sri gtc seats in the Astra gtc sports as the only have cloth ones or will it bring on airbag lights 

Hi folks,

I'm about to change the rear shocks on my car, and according to the info on the Vauxhall workshop manuals website the bottom bolt that connects the shock to the suspension arm should not be reused, but a new one fitted.

The torque settings given are to tighten initially to 150 Nm, and then tighten a further 65 degrees. This suggests to me that it's a stretch bolt. Am I correct?

In all the years I've replaced shock absorbers on various Vauxhall cars, this is the first time I've

Hi,

I've already found the how2 for changing the front and rear pads, but no mention (that I can find) of also changing the rear discs on a 2.0 CDti with 292mm discs.

Anyone know the socket sizes I need, and what the torque settings are?

I have a rewind tool, and it was previously mentioned to me that both pistons need rotating back in clockwise. Is that correct?

Also, I have a traditional handbrake that is operated via a lever. Anything I need to know about before attempting to change the d
