RC 2-inch, Lower Control Arm Bolt defeated me; Video of Half Axle issues

So I finally decided to put the RC 664 2-inch lift on my commander. 2006, Hemi, 80k miles.

Tried to get it done with my fellow gear head friend and the lower control arm bolts were seized. After about 3 hours of work we got the drivers side out and after another 3 hours we hadn't got the passengers to move in any semblance of a direction that would lead to success. We ended up putting it all back together and in defeat I called the local off road shop for backup.

Knowing that the bolts were probably goners I ordered some new LCA bolts from the dealership and handed over the lift kit and new bolts to the pro's who put my lift on for $200. Money well spent in my book.

The bad thing is that while we were dorking about we cracked a boot on the passenger side so that ended up with a new half axle.

After a few hundred miles I've noticed a good clank on the driver side when I first accelerate and when I let off and then accelerate again. I slapped a GoPro on it and that didn't really show me much. I'm trying to decide if it is a half axle on the driver side issue or not. I'm tempted to just replace it and see if that solves the problem. For the curious here is the GoPro vid on facebook: GoPro of Fwd to Rev and back

Bottom line is that the 2-inch lift looks awesome but it seems like I am shaking all the gremlins out of this thing as a result. Any input as to the half axle is appreciated.

i'm guessing you might just have loose bolts...are you sure the shop torqued the strut nut back down, sway bar links, etc... they can def cause clunking when shifting

That strut nut is a common one

That'd be where I start, since you had them work on it take it back and have them check to see if everything is still tight.

I would have thought that but with the GoPro I can see the inner portion of the drive shaft move up and down when shifting from Fwd to Rev.

It never hurts to pull the tires off and hit everything with the torque wrench to make sure of that it is all snug.

Dude, I hear you on the lower strut bolt... mine were a son of gun. Brute force eventually won on both sides:



As for the clank issue, sway bar end links are a common cause and a cheap fix, being yours have 80k it wouldn't hurt to replace them regardless.

I had to replace the front diff mount bushings on mine at about 60k. They will cause a heck of a "clunk".
