What we found:
- Front u joint to flange bolts were loose (all - of - them)
- Back u joint to flange bolts were rusted on tight; had to cut off with grinder
- Back u joint assembly had no grease zerk fitting, was old sealed type; front had zerk!
- Both u joint assemblies were in dire need replacement; loose, grind-y, gritty, nasty.
- Some bolts were self locking nyloc and some were nut plus lock washer and at least one was just nut without lock washer.

| Grind baby grind! |
Some notes from the [MG-MGB] yahoo group:
- heat to free rusty nuts, or use torch plus birthday candle trick
- remove zerks and plug with bolt if worried about loosing one on road; however this may unbalance shaft a bit
- manuals call for self locking (Nyloc) nuts, but lock washers ok; suggest a drop of blue loctite as well
- ordered all new driveshaft bolt sets when we ordered new u joints
- marked up the shaft in two diff ways (paint, dremel engraver) which was good because paint came off at one location
What we will do better next time:
- add some extra grease in the u joint bearing cap ends before reassembly; after installing the zerks and using grease gun, extra grease only came out of 1 of the 4 bearing cups - I couldn't tell if grease even made it into the other 3 (all 4 come with some grease, but more is more better)

| Can't get the u joint bearings out of the u joint assembly? Cut it to pieces and weld bits to underside of car as a warning to others. |
 |
| We will not be satisfied until complete destruction is assured. |
