I've used this adapter lots of times and normally it's a pretty good fit, perhaps as you say this plug perhaps is a little different. Should have actually paid attention to it's recess once removed, but here's it's "Hedgehog"
- Magnetic 'hog
Gearbox oil wasn't completely grim, but will change regardless. I managed to pick up a 20 litre drum of fully synthetic 75W80 for an excellent cheap price, so I am not planning to reuse gearbox oil for the foreseeable! Plenty of changes before 20 litres is consumed
Wishbone replacement went ok, other than I did the rearmost bush's bolt last and it massively fights you to get the bolt aligned with the subframe!! Will do that one first on the other side.
- Rusty old, alloy new
Interestingly, the new SKF driveshaft for passenger side has a nut which matches that taken off.
Not so much interesting, more "annoyingly" the other new driveshaft, also SKF, doesn't include a new nut.
I've decided to get my eBay driveshaft nuts on the go instead - again "self locking" but with huge integral free spinning washer.
- Nuts, nuts glorious nuts!
Final image, the finished side:
- New 'shaft and new 'bone
I'm well impressed
