Failed and had to be towed home!!!!

1. Cut out and replace o/s and n/s rear chassis members where corrosion has holed around spring hanger.
2. Replace worn spring bushes
3. Cut out and replace corroded pannel around the front of the n/s rear suspension spring.
4. Repair oil leak from diff
5. Replace rear flexible break hose, contaminated and perished.
6. Clean off all underseal so that all patches can be inspected.
The thing is really solid. They just laughed when I said it had a MOT.
Well some upside down welding great

Btw the diff is leaking from where it meets the propshaft, is this seal easy to do?
Thanks
