Snowdrop had developed a problem. The back end was twitching and there was a knock. I got the back end on axles stands and as soon as I took the wheels off I noticed the problem.
One of the tie bar brackets had sheared at the axle. I can do one of two things:
1. Replace the axle.
2. Get the bracket welded back on.
Since either option invloves dropping the axle (2 hour job) I decided to remove the axle and try option 2 first. I'll also see if I can clean and paint the axle while it is off the car. A tin of black Hammerite & a paintbrush beckons...
