My wishbone to tie bush is gone (marked in red) as far as i see, replacement involves removal of the tie, so i have few questions and please contest my assumptions
my rear have no sway bar, image is not mine, it is for the purpose of visualization only
In order to remove the tie i gonna have to remove springs and undo bolts in yellow then it should be off
will differential hang on pendulum (front hanger) and subframe or i need to support it underneath?
do i have to undo anything else, anything else to have in mind before attempting the job?
anything else worth replacing while there?
can anyone confirm that tie bush is the same as lower pendulum bush?
I swapped my differential last August and replaced a number of bushings while I was at it, but I don't remember which bushings were the same. Here's the website that I used to get part numbers to order what I needed. You can use it to see which bushings are the same.
I had to drop the whole subframe for the differential swap, but I think you can accomplish what you need to do without dropping the subframe. You'd have to compress/remove the springs, and you would need to support the subframe because it won't hang there without the rear hanger. Not sure how safe it would be, I guess it would depend on what you used to support the subframe while you remove the hanger and the other pieces.
If you have access to a car lift and a hydraulic lift cart, it's actually not too hard to get the whole subframe out which would make everything easier and safer. Then you could get a good look at all the bushings and see what needs to be replaced. If you leave it up in there, just be sure your support is stable and somewhat heavy duty. I would guess the whole subframe weighs 400 pounds or more, but I don't actually know. It's heavy though.
I think you should plan on replacing the upper spring pads while you're at it. Might not be a bad time to suck out the diff fluid and refill with fresh since the hanger will be out of the way. There's no drain plug, and you can't take the cover off without removing the huge hanger bolts, so a hand operated or electric transfer pump is needed to suck out the oil.
