Wouldn't locking the axle solve the problem?
That sounds right but how would you do it? Couple of big vice grips?
sleeving it and drilling holes to put bolts through both parts may work.
Good idea but set screws would be easier than drilling the axle under the car. So all OP has to do is turn a sleeve on his home lathe and drill and tap enough set screw holes to keep it together to the dealer. Piece of cake.
How far is the car from the dealer? Could you go old school and have someone tow you slowly with a tow strap? Under the present conditions nobody would probably notice.
