One of the rear wheel bearings had excess play, the brake pipe across the rear of the chassis had signs of corrosion and there were 3 areas of corrosion underneath. The most serious being a hole about 1 inch x 1/2 inch that the tester managed to poke in a front out rigger. The other two are pretty minor a very small split in the passenger floor pan near a seat mounting and a small split at the edge of the boot floor. The last two are not in a particularly structural position but were within 30cm of a load bearing area so are a failure under the MOT regulations.
I'll get the corrosion plated by the MOT place just to get a quick pass.
I took the halfshaft out last night and rebuilt it tonight with a new bearing and a new genuine metalastik rotoflex coupling that I was lucky to pick up cheap on ebay. It's been a long time since I've done a wheel bearing on the GT6, I did have a stock of shims and spacers for setting up the end float but I can't find them anywhere in my Aladdin’s Cave of a Garage. Luckily though the existing spacer was the right size to give about 1 thou of end float which is within tolerance. I remember last time I replaced a bearing I had trouble getting the outer bearing off the hub as it disintegrated leaving the inner race in place. So this time around I treated myself to a bearing splitter tool, that certainly makes the job nice and easy.
So just need to change the brake pipe and put the halfshaft back in, I can then book the car in to get the corrosion plated and the car retested. I always take my car to a place that does free retests on principle, however they have now reduced their free retest time limit from 14 to 7 days and I'll probably miss the 7 day cut off which means I'll have to pay for the retest which is a pain....
