I'm going to fix the leak (driver side cover) differential I know there is stud need to take off but my question is I jack the car from (crossmember) under differential is that will be affect the stud ? I mean it's going to apply pressure to the stud or change the balance or it's wrong to jack the car from there ? I need to make sure before I took the stud off ? I don't know if I am supposed to jack the car from there or from the side ? This is how I jack the car Do I am ready to take the stud off yes or no?
I don't want to take the stud off then I can't put it back because the way I jack the car ...?
You're not getting the diff out without dropping that cradle. You need to move the rear jackstands to under the frame rails are the factory tie down points. Unless you're pulling that side cover with the diff in the car. Remember, there's a rubber mount between the cradle and any tension on the driveline so yank that stud, the other 4 fasteners will keep everything from shifting.

. So it's okay to take that stud off with the way l put the jack ? lam only going to take off the driver side cover ...even that l can't move the jack now because l took off the CV axle already
By the way ldon't have leak there but this one happens after I change the CV axle with the gasket .. then suddenly the leak start from there I mean we're the (cover) and I noticed this is very common to have a leak in the driver side cover ...
Mine persistently leaked on the passenger side even after new output shaft seals (2x GM), and all new O-rings, and new axle. The only fix for me was to replace the diff's pressure vent valve with an open vent line. And yes I tried a new GM vent valve...
I can't take the stud out there's no space and impossible to find the net that will be work and fit with the stud so I end up to weld the net to the stud and this time they come off easy .what you think guys do l can use the stud again or no ?
If you jam 2 nuts together you can then spin the stud out as well. Grind the weld off and see what's left of the stud.
Believing men the mechanic guy he's my friend he come from the shop to my home to try to take it out the stud it's only enough for the OEM nut l took it out I can't find any two-nut thinner to go together there I cut two nuts the both to make it fit there no luck they get spin together and no space even for the winch to hold it ..the nut inside start to spin destroyed the thread so doesn't work .. once l weld the nut they come off very easy. So ldon't know if l can add a washer to same stud to make it work
Is there any aftermarket stud to replace the OEM ?
... I ordered the stud and lwill take a while to get it my question is do l can install the cover back and finish everything and add the differential oil and I'm not going to drive the car until l get the stud to install ..is that okay or no ? or l just wait for the stud to install the cover same time ?
By the way do I need to torque the bolts for the cover than after that install the stud or no ?

My recommendation is to wait until you get the stud in your hand and confirm that the stud will thread nicely into the cover…You don’t want to find out the stud thread pitch is wrong after you gone through all that work with sealing the side cover…
From someone that has been there, here are a few assembly tips for you to get a fix the first time
Assembly aid to ensure you do not shave or damage the side cover “O” ring during cover install Assembly Aid> Side Cover Dowels Pins
To reduce the risk of side cover “O” damage (pinching/cutting the “O” ring) and/or bolt hole to cover misalignment during installation of the side cover;
Make from bolts M8X1.25 X 80mm or equivalent. Cut the heads off the bolts, thread into the case “by HAND ONLY” slide cover on to the dowels and install the cover on the case.

Keep sealant away from the 0-ring.
28. Install the differential cover to the differential.
