I am new to the site and love the forum. I am having a problem finding lower control arms for the front. The car is a 2009 g37x coupe with 114k miles. I have looked all over the Internet for the front lower control arms for the car and the only place I can find is the infiniti parts website. I called my local nissan dealership to get a price and part number to confirm what I had found. The dealership told me that all the coupes (at least) have the same part number lca 545001, and545000 for right and left. However the infiniti website on the parts list (not the diagram ) there are exclusive part numbers for rwd and awd. Needless to say I am a little confused. Have any of you run into this problem before or have any insight into this it would be greatly appreciated feel like I am

Thanks
Brock

 

Hi Brock, welcome to the site. I would go by the Infinti parts listings, if it lists unique part numbers for your AWD coupe vs. the RWD model that's what would be req'd. They will list the same part # if it's used for other models.
Are you needing these because the bushings are shot or was there damage?

 

The lower ball joint on the front left side is bad and has slack. We are also replacing the upper control arms with z1 and replacing the inner and outer tie rods at the same time. I very picky about when I replace something on a suspension I typically replace as much as I can afford or at least the more difficult parts to replace at once so I don't have to work on the same area again.

 

Also thanks for the welcome!!!

 

It lists part # 545001BA8A for Right LCA ($241.41) and 545011BA8A for left LCA
($259.09) for AWD Coupes

FWIW the RWD coupe LCAs are 54500JL02B Right, 54501JL04B Left, both sell for $259.09

 

So is infiniti the only source for these lowers? Because that is the only website I have found. But I can not find any reference to two different arms except the infiniti website. My question is is there any actual difference in the parts? According to what my local dealership and the Dallas infiniti dealer there is no difference and I can get the the moog arms for the price of one from infiniti. Hence my confusion. I don't doubt what you guys are saying. Thing that throws me off is the nissan and infiniti dealer say that the rwd and the awd arms are the same.

On a side note as soon as these original arms are out I am cutting the ball joint off and putting heim joints on and replacing the bushings with delrin. Screw the bs nissan design

 

I found the best price on the awd LCAs (for my sedan, which should be the same parts) was from a NY State dealer via ebay...under 200.00 each including shipping...but it was a while ago...i think there are some aftermarket oem type options...maybe check rock auto and use a coupon

 

I'd call discountinfinitiparts and see what they say, they are a Infiniti dealer that just uses that website to sell their OEM parts, but they are one of the largest and best. They may be able to confirm if indeed they are different parts. Like I mentioned prior they should be since they have dedicated part #s and also different pricing, at least for that right side.

 

If it helps; the parts Blnewt linked to are the right part number, but (and this may be the source of consfusion) the picture is of the 2wd front lca. The awd LCAs look distinctly different in person and have completely different mounting points from the 2wd parts pictured

 

Thank you guys I did order from discount infiniti parts and ordered the ones recommend by you guys. I don't feel too bad even the nissan guy thought they were the same. Looking forward to getting this girl back on the road
