Here are the parts you're needing, most likely. Mevotech lower control arms?
So, this thread is really about replacement parts for the AWD front end suspension, which is a PITA to deal with. There's not a lot of information. I went through this same gauntlet several weeks back, and even posted a thread as well. In short, I found a manufacturer who supplies both the compression rods and the lower control arm (forward) for the 03-06 G35X, with all OEM-style bushings and joints in place. Best part is that all four items only cost a little over $300.
Us AWD drivers need to help each other out. For anyone here looking for the answer, check my first post in this thread (Mevotech lower control arms?
) from a few months ago. The four parts linked in my OP were ordered, installed by me (in addition to new struts), and work flawlessy. My 183K mile 2006 X is now very smooth and quiet up to at least 100 mph.
EDIT: The link provided in my post from the other thread will likely lead you to CARID.COM, and to a page which says "out of stock". Just copy the part number and do a Google on those part numbers, and somebody else will have them. Also, O'Reilly's now sells parts for the AWD suspension, at a a 50% premium to the CARID.COM prices you'll see on those links form the other post. I think their part numbers even align with Mevotech's, although O'Reilly's has branded them "Import Direct" or some crap like that. I think they're identical to the Mevotech parts, anyway.
