rear upper control arm

I've been hearing some clicking/clunking lately in the rear of my Liberty and noticed that the body mounts of the rear upper control arm are loose. I think the rubber bushings inside gave out. I can easily move them up and down with my hand. These shouldn't move loosely correct?

Has anyone replaced this yet? Easy/hard job?

Thanks

Yea, if you can move it like that most likely that's the source of the clunking. The ball joint that attaches to the top of the differential is probably shot too.

Pretty easy to replace - hardest part is usually getting the ball joint to separate from the diff. You can work to remove the joint from the clamp-like component attached to the diff or remove the clamp from the diff when you loosen the tri-link (upper arm) and remove it. Then separate the joint from the clamp when it's more accessible.

Purchase a Mopar tri-link. Yes, there is a big price difference between the factory and aftermarket pieces but this is a "get what you pay for" situation. The factory unit will last much longer than aftermarket so you don't have to do this replacement again for a long time.
