All 9c1 cars had a recall notice due to a problem with the rear trailer arms to the rear axel. Seems that the sway bar may tear at the point of conection to the trailer arms and thus making it possible to loose the entire rearend of the car. Now they only recalled the cop cars becuase they use their cars for "severe duty" Now you Impala owners would never be severe on your cars would you? Well since you are running the same rear set up you may wish to check the rear ends out where the sway bar meets the trailer arms.

Mine just got fixed toady under the recall notice and yes there was a 1/4" tear started on the passenger side.

Just a thought for you all with stock rear stuff.

Is there a recall or TSB # on this? Tell me tell me tell me!

This is of concern since my 9C1 sees newfound severe duty.

I've already had campaigns 96005 and 96010 addressed, but tell me if there's something new.

Replace the arms with aftermarket. The GM Recall just takes REALLY REALLY crappy arms and replaces them with a set that is only REALLY crappy (one REALLY, not 2 [img]smile.gif[/img]).

If you want to do it yourself anyways (about 2 hours work, fairly simple) and would rather spend $40 for REALLY crappy arms instead of $160 for (about a thousand times better) BMR or other aftermarket arms, then the parts are available from Dal.

Obviously, I would recommend just going aftermarket on this one.

Well they did mine for free book said half hour for one guy took hour and half and three guys. Looks like all they did is put the same arms in, added some metal sleeves around the blots and some bracket plates that spread the effects over a larger area. I am trying to find a set of arms that will center the rear wheels in the wheel well, any cluse as my bolts are all fresh, shinny and easy to remove now?

The information is aftey campain #96005 and or V9887 its the rear lower control arms and its part#10289786 they put in.

If you are retaining the Factory Rear Sway bar the Stock LCA's "should" be OK. Provided they are the upgraded sesign with the sway bar attach bolts running vertically through the arms. I would still inspect for cracks whenever you rotate the tires.
If you are running ANY aftermarket bar you CAN run the stock lowers... but You should use larger bolts(I use 12mm X 120mm) as well as hardened washers on both nut and bolt sides of the mount.
My stock LCA's were removed after approx 70K of street, drag and autocross use. They were both cracked from the lower (rolled) egde around the front sway bar mount plate. The drives side was also cracked on the top forward bolt hole. (Bar trying to pull it down through the arm.)

For those of you racing I think an aftermarket LCA is a worthwhile upgrade both in performance and safety. Folks working around "Race Class" or budget issues can certainly utilize the factory arms just inspect regularly and ensure everything stays torqued! Repair or replace whenever you find a cracked or broken part.
