I fitted new rear springs and shocks on my GTs. When it went in for the service tother week, it was marked as an advisory as the n/s rear was leaking.
I called into Euro car parts in town and got the bits. Along with an air filter as this wasn't changed during the service. Only cost £150 give or take a few pence, it only took about 4 hours on the drive with my new little trolley jack from that there halfords. Not a bad little jack for £25.
I'll give it a week and check the bolts again for tightness, as I didn't have my torque wrench to hand.
