Well we all assume it is a HMMWV, I am going to guess you have a M1097R1 with a GVWR of 10,000lb by the serial number, this makes a significant difference.
BTW your truck is really not a 2007, it was rebuilt to M1097R1 standards in 2007, most likely it started as a 1980s/early 1990s M998
SO assuming that here we go.
Download TM 9-2320-280-24p-1
A few pages under the table of contents you will find a page (5) with all the UOC (usable on code) table.
Most of the parts for the M1097R1 is the same as the M1097A1
The UOC for the M1097A1 is AVY, write this down as it is important.
Go to the TOC and scroll down to rear axle group 11
You will see Rear control arms, ball joints, and mounting hardware, click on that tab.
Then scroll up to figure 12. EDIT, sorry fig 152
You will see the control arm bushings are #7 and #21, scroll down to the parts numbers and you will see they are the same part number for all locations (7 and 21 are the same part number)
You will also notice there are no UOC numbers listed under the part descriptions, this means the same bushing are used on ALL vehicles this TM covers
Now lets look at the upper ball joint, it is listed as b which is part of #8
Then you scroll down to the parts list and you will see TWO listings for part number 8, one of which will have your UOC of AVY listed under it, this is the correct part number for your truck (now you know why the UOC is important)
Now you can search for ether the USN number or the manufacturers part number.
Now you know how to fish!!
