1986 'Burb Lower A-Arms
 

Well, horror story from getting the shocks done.. they tore up my control arm (said something about breaking two wrenches... I don't know what that could have been about ;) )

Now I need a lower control arm before \the local alignment shop will even touch it...

So I'm searching, and I find that LMC has a Lower A-Arm assembly for $99... but it's for 3/4 ton only...

I'm in search of both a left and right Lower A-Arm for an 86 1/2 ton suburban...

Anyone who can help??

Here is what Hollander says will work for an 86 1/2ton Suburban lower control arms:

I am sure someone has a set in your neck of the woods. Junkyards would probably get around $50-60 each for them or if you have a U-Pull-It type place you can get them for $15-20 each. Hope you get a set.

My back has been doing evil things of late, and today was the first time I got a chance to get under the frame.

I did not observe any cracks, bulges, or any other sign that my A-Arms were bad... what am I looking for to indicate that I really need a new one?

Has anyone used one of the PST or other brand front end rebuild kits that include all the bushings and rod ends? Any opinions?

I used a front end rebuild kit from http://www.performancesuspension.com/ Nothing short of a top notch company and parts. I highly recommend them. Others swear by PST. I'm thinking you may need new bushings instead of the control arm.
