Ok cars fall into 3 categories for towing.
one: Can be towed 4 down with only a base plate Tow lights and aux brake install
one.five: as above but special procedure must be followed.
Two: Can be towed 4 down WITH MODIFICATION beyond the above. For Front wheel drive that is either an axel lock or a lube pump. I prefer the axel lock as it is a half-shaft (the drive shaft on one side) with a special clutch in it. like the old Locking hubs on JEEPS (Same techonology) it is 100% reliable provided you remember to UNLOCK it when you tow. Has a few other advantages too With this in the UNLOCKED position the wheel it is attached to spins freely like a rear tire.. The other one spins the differerntial but that' sonly a tiny bit of drag and runs in oil so no lube issues.
The LUBE pump pumps transmission fluid around using Motor home electricity to do the job.. Keeps the bearings lubed. Safely.
I used the first on a car that had the clearance for me to reach behind and lock/unlock the axle. the 2nd on one that does not have the clearance.
And then we have the 3rd type of car. Can not be towed 4 down no matter what.
