Got the MC arms in the other day.
I was able to swap out the front 4 arms Wednesday. As the following pictures will show, the RC arms flex-joints and bushings gave out within the 3 years they were on, even with being greased.
It's hard to tell in this picture but this bushing is all cracked and ruined.
This is a video showing the play in the driver side upper flex-joint. Obviously this contributed to my rough ride.
My front driver side UCA bushing on the axle end isn't helping:
Front arms in:
I took it for a test drive Wednesday night with just the front set swapped. It was a dramatic difference in ride quality. The front end floated over bumps in the road, and the rear still took jarring hits.
Yesterday I was able to swap the rear arms out.
Here is a picture of the old, POS RC arms.
Also, an interesting difference between the arms. Look at the size of the shank for the RC UCA's vs. the MC. I always thought they looked small, but figured it may just be that way for all manufacturers. Obviously not..
After getting the rear arms in, I drove it again and the difference is amazing. I finally feel like I have a great ride and it just absorbs the bumps in the road. I don't receive jarring shocks each time I go over a pot hole. The Duroflex joints provide a much better ride than the RC poly bushings and X-Flex joints. Also, I probably won't have to worry about ripping a CA bracket off now because these are softer than the poly bushings in the RC arms. I can ride comfortable in the Jeep now.
