I didn't check on trailer arm bushings when doing strut rods. My mistake.  Just took a look and , I'm assuming there bad, as the shims are completely rusted and looks like never had been removed.  Going to order bushing kit , along with the tool to install. Also rear outer spring bushing kit. Looks like only thing I won't replace is the spring itself. Thanks for advice.  Sorry. I'm long winded

I purchased polyurethane bushings by "Energy Suspensions" which do not require a special tool for installation.  Not installed yet, but maybe others can comment on them.  Also, stainless steel shims are available to replace originals.  

Thanks, must appreciate it. Can you all the advice I can get.

So here is the Manufacturer's website to get more information:  Teamenergysuspension.com.   There are many sources that carry their bsuhings.

(There is also a similar-sounding site, Energysuspensionparts.com, a dealer which sells these, and other suspension parts)

Thanks Sasza79. I will check l it out. Its winter here, so trying to get the parts I need to install in March or maybe February.  

Question on the trailing arms bushings.  Once the trailing arms are out, are the bushings hard to remove and replace like the A arm bushings, or do they just come out and new ones put in?

Well, After doing a few, my own, and others, let's just say they are NOT a take and replace project. 

Thanks for the help. Just getting ducks in row so when I start this project In a month or when weather gets a bit warmer here.

I will be doing mine soon on my '79 C3.   I already have my trailing arms removed.  I will update and let you know how it works out.  I will be removing the original OEM rubber bushings, and  I will install the replacement red poly-bushings made by Energy Suspension.  

 I haven't pulled the trailer arms out yet. But found a video on you tube for taking out bushings , which looks simple enough. It doesn't have a title except for 002 under its video picture. its by Greg  Ballenger.  Came across it looking how to remove trailer arm bushings 69 corvette. If i can figure how to send the link i will.
