I know this has been discussed, including in my last thread on my collapsed jackpoint, but I wanted to collect opinions on proper jacking of the 124's rear. In my case, at the moment, I cannot use the driver's side jackpoint because of rust damage. I have done a search, and have heard a lot of people suggest jacking it up by the car by the diff, then putting stands under the subframe mounts ... but I also saw a couple of caveats that lifting by the diff should not be done on a 124. I know what's OK on a 123 is not always OK on a 124, so I wanted to be clear.
Bottom line: I can easily and safely jack up the front of this car, but for some reason, that particular rear jackpoint is a disaster. I need to do the driveshaft flex discs and center bearing, and at some point soon I need to do the diff bushings. Is it OK to lift the butt of this car by the diff or is that a no-no? What else can I lift it by? And where should I put the supports?
Or do I have to learn how to weld really, really soon?
I know some of this is running over what people have already said or suggested, but I just wanted a 124-specific rundown of safe lifting points. Thanks.
