I need to replace the bolt that is on the passenger side control arm. Is it the one that is right behind the lower motor mount and is pretty long. On the other side of the bolt there is some sort of nut that helps tighten the bolt down.

My issue is when the control arm was loosened at some point about 2 years ago it was never tightened all the way. I have brought it to several alignment places and nobody could figure out why my car would "clunk" every time the weight transferred. The other weekend I put it on jackstands and started torque specing everything myself. The last bolt I checked was this somewhat hidden bolt behind the lower motor mount(you have to take lowe motor mount off to get to it). Well since it was hand loose a couple of the threads were worn. I have since tightened the bolt up, but the car feels like it is getting loose again.

So I would like to just buy a whole new bolt if that is possible?

The dealer should be able to get you that bolt without any problems. 06506039AA for the vertical bolt, 06504742 for the horizontal bolt, 06505595AA for the nut for the horizontal bolt.

That nut has an "arm" on it so you don't have to put a wrench on it to hold it in place once it gets started on the threads.

Yea the nut on the back is there and secures it...have no clue as to how it came loose in the first place. Whatever the reason thats the one that has the worn down threads.

front lower control arm bolt = 120 ft/lb

That bolt threads into a nut that's welded to the inside of the chassis. Chances are yours was rusted in place and when you went to remove it you broke the welds holding the nut in place.

IIRC you can cut a small access hole in the floorpan to put a socket on the nut to remove it.

Hello can you explain a little more please. The bolt that runs horizontal on the drivers side - does it have a nut at the end with this “arm” mechanism also? Does the nut fall off or is fixed on the nut on the drivers side. Passenger side it falls off. Reason is..... my sub frame on the drivers side near this area was rotted and welded. The shop that did the weld - welded over this opening hole. So you can’t get the wrench in there or have access to the nut??? He needs to cut a hole now. Hopefully this is easy. His mistake. Thanks.

So true! This information is so important and informative! Your learn from others which is amazing and sharing what happened all unique things. My car is very rusty northern Canada car. But an amazing srt4 2004. I can already for see this happening. Please please. Does anyone here know how to 100% avoid this lol from happening. Heat in the right place. ? Certain other tip. Plus if it broke the weld and you cut inside and tightened ok and all is good. Shouldn’t you re weld the area of where it was secure again? I know this is gonna happen but my bushing must be replaced.
