Default Rear sway bar question.

While I am replacing my rear struts and mounts I am replacing the rear sway bar bushings, endlinks and exhaust hangers.

At 92k I was ridding around on springs in the rear, both shocks can be compressed with little effort (I'm talking my thumb and the ground) and one barely rebounded while the other had to be pulled apart. I imagine my struts are in the same shape. Those will be next on the list... Bump stops were also busted in half on both sides. The shock mounts just went out so there was a symphony of racket going on back there. I figured while I was in there I would replace the endlinks and swaybar bushings since those parts are really cheap.

*edit... Figured out the bumpstops...

My second question is regarding the swaybar. What is the proper procedure for removing it and installing it with the proper load? I have read about jacking up the trailing arms for removal but I have also read that people have removed the bar without lifting the trailing arms. Clearance seems tight between the control arms and the endlinks... Anyone here do this recently? Any tips for correct installation? Thanks in advance...

Theres no adjustability with the stock rear sway bar setup. Its simply a bolt in affair, remove and reinstall whatever way is easiest for you.

Thanks, just got it out a moment ago.

Do you know how to remove the exhaust hanger support bracket from an existing mount?

If its the part I think you're talking about you'll have to slightly bend the metal to remove the old mount. Just use vise grips or channel locks to rebend the metal once you have the new mount in place.

You're talking about these right?

You can simply pull the rear sway out, its a bit of a tight fit, but definitely doable without removing anything else.

On reinstall, I like to tighten upper endlink pinch bolts with the suspension loaded - IE, the car on the ground. It's good practice to fully tighten many suspension bolts only when the suspension is loaded - but especially ones that involve bushings like this (same principle with control-arm bushing bolts) whose components rotate.

Yeah those buggers, metal reinforcement seems to be bonded to the rubber. I was thinking about hack sawing the rubber. I'll figure it out, thanks for the suggestions.

Is there enough room to tighten all those bolts with the car on the ground? Don't think I'm small enough...

You sir need to invest in some ramps, I can drive up onto mine but if I lower the car onto them I can do work with the weight on the wheels. It creates the space you'll need in a safe fashion
