Since the dealer replaced the rear lower control arms due to a recall (after all these years), there was a clunking noise at the back. Due to the design of the new arms the stabilizer bar touches the control arm behind the rear stabilizer bolt. If you hit the bar it vibrates against the control arm. I used a 2.5 mm washer as a spacer on both sides at the rear bolt between the bar and the control arm. Problem sorted.

A few weeks ago, after picking up the new arms for the recall from the local FCA dealer, I was not at all impressed with the "new & improved" version of the rear lower control arms provided with the recall! :banghead:
I had all intentions of bringing them home and installing them myself. I had worked this out with a mechanic friend of mine who works there.
I actually had removed one of the OEM arms and then opened the Mopar box and laid one of the so called "new & improved" arms beside it, see picture below.
I quickly realised the OEM arms are constructed of a much heavier metal and a more robust design and they actually weigh more and appear to be overall better made arms. :shock: :shock:

Needless to say, I put the OEM arm back on my Jeep and declined to use the recall parts. I plan to hold on to the new arms just in case I ever need them.

Now the caveat: I don't live in a rust belt state where many of the suspension parts on vehicles can be exposed to the highly detrimental effects of road salt.
So if you live where salt and / or rust may be a real problem you may want to consider the recall performed???

I just was not impressed with the design or the quality of the replacement parts....
The new ones are made out of a thinner metal, kinda remind me of the POS stamped boomerang! :banghead:

Due to the size thinner material can be used to achieve greater strength.

Those updated LCA's are actually the '02 KJ's original LCA's and trust me can take a beating plus you never hear about the '02's rusting apart like the newer models.

Just got thru with myself today. After the recall there was a clunking noise. I took it back to the dealership and they had to re-torqued the bolts. The clunk is gone.

I agree with WWDiesel. Should have ignored the recall and kept the original arms (took a lot of blood, sweat and tears to replace the bushings a couple of years back). I live an a very dry region where rust is not an issue. The dealer insisted on doing the labor (understandable from a warranty perspective) and keeping the old arms. The shocking part is the fact that the left arm rear bolt and the stabilizer bar bolts were only hand tightened when I got the Jeep back. That was the first and last time they did any work on this Jeep.
