help removing old rear shock perches

i'll be changing out my coil-overs in a week or so, i have tried getting my rear perches out before, they just spin with the bolt holding them in. is there anything i can do to get them out without removing the entire rear arm?

help removing old rear shock perches

Need to hold the shock rod still while loosening the nut with a wrench. Hopefully your shocks have a flat section on the end so you can grab on with a pair of vise grips.

In that case, I suggest vise grips on the shock rod in the wheel well. I would never recommend a freakin blow torch for this job.

Unless you have some big ****ing vice grips it will spin as you are locking it onto a polished round object....Im not saying to melt the mother ****er, but heat up the top bolt on the shock tower, let it expand while gripping the shock rod in the wheel well and crank it off.

the perches, the part that hold the rear springs in. They sit on top of the rear control arms.

You can typically knock the nuts off with a quick blip from an impact. If not you can get a cut out socket, or reach threw socket and place an allen key in the top of the shock while turning the bolt.

MY h&r comes with a square tip, use a socket or adjustable wrench to lock the shock rod, Bilstein shocks needs allen wrench tool

ok guys, i'm pretty sure this part is the prech, not the shock. i got the shock and springs off fine. This piece sits on top of the rear control arm with the spring, a bolt holds it to the control arm. When i try to loosten the bolt, it just spins, there's nothing to hold it in place. I can't fit an air tool under there because the axle is a couple inches just under it, blocking.


in this photo, they are the gold portion between the control arm and the spring.


here is another pic showint an example of perches that i am trying to remove. They are the small circular pieces pictured in the lower left and right hand corners.

I'd look up install instructions on the manufacturers website, or on other DIY guides.
